Spring Cloud Skipper Overview
Skipper is a lightweight tool that lets you discover Spring Boot applications and manage their lifecycle on multiple Cloud Platforms. You can use Skipper standalone or integrate it with Continuous Integration pipelines to help implement the practice of Continuous Deployment.
Skipper consists of a server application that exposes an HTTP API. A shell application provides easy-to-use commands to interact with the server. The server uses a relational database to store state. Documentation to call the HTTP API is available in the REST API Guide.
Applications in Skipper are bundled as packages that contain a templated configuration file and a default set of values that are used to fill in the template. You can override these defaults when installing or upgrading a package. Skipper provides a means to orchestrate the upgrade/rollback procedure of applications between different versions, taking the minimal set of actions to bring the system to the desired state.
Skipper’s design is influenced by a large number of projects in the Kubernetes ecosystem that perform resource templating and/or orchestration, hence the nautically inspired project name Skipper.
In particular, Helm's approach to present the user with a familiar apt-get or brew like installation experience was a big influence.
3. Features
The main features are:
-
Define multiple platform accounts where Spring Boot applications can be deployed. Supported platforms are Local, Cloud Foundry, and Kubernetes.
-
Substitute variables in Mustache-templated files that describe how to deploy applications to a platform.
-
Search Package Repositories for existing applications.
-
Upgrade/Rollback a package based on a simple workflow.
-
Store the history of resolved template files (AKA 'application manifests') that represent the final description of what has been deployed to a platform for a specific release.
-
Use a standalone interactive shell or an HTTP API.
4. Concepts
The main concepts are Platforms, Packages, Repositories, Releases, and Release Workflows.
Platforms are where your apps run. Skipper 1.0 supports deploying applications to platforms by using the Spring Cloud Deployer family of libraries. Doing so lets Skipper deploy Spring Boot applications to Cloud Foundry, Kubernetes, and your local machine. You can configure a single Skipper server to deploy to multiple platforms, with each platform identified by a unique name.
| The Spring Cloud Deployer libraries for Apache YARN, Apache Mesos, Redhat Openshift, and Hashicorp Nomad were not bundled with Skipper in 1.0. Donovan Muller has provided support for Redhat Openshift. |
Packages define the basic recipe for describing what to install on a platform.
A package can define a single application or it can define a group of applications.
It contains descriptive metadata, the location of the Spring Boot uber jar, and default application or deployment
properties.
The location of the uber jar can be a Maven repository, docker registry, file location, or HTTP location.
A package is a collection of YAML files that are zipped up into a file with a naming convention of name-version.zip (for example: myapp-1.0.3.zip).
Repositories are where package metadata and zip files are hosted. Repositories can either be 'local' or 'remote'. A remote repository is one that is only accessible over HTTP. Any arbitrary web app that serves up files off a file system can be used to host a remote repository as long as certain directory and file naming conventions are followed. A local repository is managed by the Skipper server and backed by a relational database. Skipper lets you search for packages that are hosted in repositories.
Releases are created in Skipper after you install, upgrade, or rollback a package. A release has a unique name that you provide to perform release operations such as upgrading, rolling back, and deleting. The release contains the fully resolved template files, also known as application manifests, that represent the final description of what has been deployed to the platform. You can also get the status and application manifest for a specific release.
Release Workflows are the steps taken to upgrade or rollback an application from one version to another. In Skipper terms, it is how we go from one Release to another on a Platform.
| An upgrade may keep the same version but update application properties. |
Getting Started
5. System Requirements
The Skipper server is a Spring Boot application. Both the server and the shell are based on Java 8. The server uses an RDBMS to store state. An embedded H2 database is used if you do not provide a Data Source configuration through Spring Boot configuration properties. Supported databases are H2, HSQLDB, MySQL, Oracle, Postgresql, DB2, and SqlServer. Schemas are created on server startup
6. Installing Skipper
This section covers installing Skipper on your local machine, as it is the easiest way to get started. The section Installation discusses installing on Cloud Foundry and Kubernetes. It also shows additional options for installing on your local machine.
-
Download the Skipper server and shell apps by using the following commands in a terminal session:
wget http://repo.spring.io/milestone/org/springframework/cloud/spring-cloud-skipper-server/2.0.0.M2/spring-cloud-skipper-server-2.0.0.M2.jar
wget http://repo.spring.io/milestone/org/springframework/cloud/spring-cloud-skipper-shell/2.0.0.M2/spring-cloud-skipper-shell-2.0.0.M2.jar-
Launch the server and shell apps by using the following commands in a terminal session:
java -jar spring-cloud-skipper-server-2.0.0.M2.jar
java -jar spring-cloud-skipper-shell-2.0.0.M2.jarThe default port that the server listens on is 7577. That is SKPR on a telephone keypad. :)
There is also a docker image hosted on dockerhub
Now install some apps!
7. A Three-second Tour
The default configuration of Skipper deploys apps to the local machine.
The default configuration also has one local repository, named local, where you can upload packages.
You can get a list of the package repositories by using the command repo list, as shown (with its output) in the following example:
skipper:>repo list
╔════════════╤═══════════════════════════════════════════════════════════╤═════╤═════╗
║ Name │ URL │Local│Order║
╠════════════╪═══════════════════════════════════════════════════════════╪═════╪═════╣
║local │http://10.55.13.45:7577 │true │1 ║
╚════════════╧═══════════════════════════════════════════════════════════╧═════╧═════╝Search for the available packages using the package search or its alias package list command.
The following example shows the package search command and typical output for it:
skipper:>package search
╔═════════════════╤═══════╤════════════════════════════════════════════════════════════════════════════════╗
║ Name │Version│ Description ║
╠═════════════════╪═══════╪════════════════════════════════════════════════════════════════════════════════╣
║helloworld │1.0.1 │The app has two endpoints, /about and /greeting in Portuguese. Maven resource. ║
║helloworld │1.0.0 │The app has two endpoints, /about and /greeting in English. Maven resource. ║
║helloworld-docker│1.0.1 │The app has two endpoints, /about and /greeting in Portuguese. Docker resource.║
║helloworld-docker│1.0.0 │The app has two endpoints, /about and /greeting in English. Docker resource. ║
╚═════════════════╧═══════╧════════════════════════════════════════════════════════════════════════════════╝Install the Maven-based Hello World application by using the package install command.
Since this application picks a random port for the HTTP server by default, we specify the Spring Boot property server.port, prefixed with spec.applicationProperties.
The prefix is due to the internal format of the template file.
The following example shows the whole command with its output:
skipper:>package install --release-name helloworld-local --package-name helloworld --package-version 1.0.0 --properties spec.applicationProperties.server.port=8099
Released helloworld-local. Now at version v1.You can now curl the greeting endpoint, as follows:
$ curl http://localhost:8099/greeting
Hello World!The release name, helloworld-local, is used for subsequent commands, such as release status, release upgrade or release delete.
To see the status of the release, use the release status command, as shown (with its output) in the following example:
skipper:>release status --release-name helloworld-local
╔═══════════════╤═════════════════════════════════════════════════════════════════════════════════════╗
║Last Deployed │Fri Oct 27 16:17:53 IST 2017 ║
║Status │DEPLOYED ║
║Platform Status│All applications have been successfully deployed. ║
║ │[helloworld-local.helloworld-v1], State = [helloworld-local.helloworld-v1-0=deployed]║
╚═══════════════╧═════════════════════════════════════════════════════════════════════════════════════╝Now we can upgrade the release.
The 1.0.1 package refers to a newly released application that changed the default value of the greeting to be in Portuguese.
The following example shows a typical release upgrade command with its output:
skipper:>release upgrade --release-name helloworld-local --package-name helloworld --package-version 1.0.1 --properties spec.applicationProperties.server.port=8100
helloworld-local has been upgraded. Now at version v2.The preceding example command deploys the new version of the application, waits until it is healthy, and then destroys the old version of the application.
You can then see the status of the application by using the release status command, as follows:
skipper:>release status --release-name helloworld-local
╔═══════════════╤═════════════════════════════════════════════════════════════════════════════════════╗
║Last Deployed │Fri Oct 27 16:20:07 IST 2017 ║
║Status │DEPLOYED ║
║Platform Status│All applications have been successfully deployed. ║
║ │[helloworld-local.helloworld-v2], State = [helloworld-local.helloworld-v2-0=deployed]║
╚═══════════════╧═════════════════════════════════════════════════════════════════════════════════════╝You can now curl the greeting endpoint at the new port and see that the application has been updated, as follows:
$ curl http://localhost:8100/greeting
Olá Mundo!To delete the release, use the delete command, as shown (with its output) in the following example:
skipper:>release delete --release-name helloworld-local
helloworld-local has been deleted.| This example, where the upgrade changed only a property of the application, is not realistic. A more realistic example is the case where code has changed so that the updated application behaves differently. |
You can also deploy the other packages named helloworld-docker to the local machine.
The examples in this section have shown the most basic operations.
Other interesting commands such as manifest get, release rollback, release list, and release history are covered in the Three minute Tour.
Three minute Tour
Picking up from where the A Three-second Tour left off, this section walks through the additional commands and other features of Skipper. Each section walks through the same set of operations, but for a different platform:
8. Local Machine
Start up the server and shell as in the three-second tour.
Now you can install and then update the Hello World application.
Start by running the package install command, as shown (with its output) in the following example:
skipper:>package install --release-name helloworldlocal --package-name helloworld --package-version 1.0.0 --properties spec.applicationProperties.server.port=8099
Released helloworldlocal. Now at version v1.You can now curl the greeting endpoint, as shown (with its output) in the following example:
$ curl http://localhost:8099/greeting
Hello World!
$ curl http://localhost:8099/about
Hello World v1.0.0.RELEASEWe use a YAML file to update the release.
This application contains a Spring Boot @ConfigurationProperty, named helloworld.greeting, so we set that along with a standard Spring Boot property: endpoints.sensitive=false.
We also bump the memory up to 2G, make the Boot actuator endpoint not sensitive, and set the port to 8100.
The helloworld-upgrade-local.yml file contains the following code:
spec:
applicationProperties:
server.port: 8100
endpoints.sensitive: false
helloworld.greeting: yo
deploymentProperties:
spring.cloud.deployer.memory: 2048m
The following example shows the release upgrade command, with its output:
skipper:>release upgrade --release-name helloworldlocal --package-name helloworld --package-version 1.0.1 --file /home/mpollack/helloworld-upgrade-local.yml
helloworldlocal has been upgraded. Now at version v2.The --package-version 1.0.1 command line option is also used to upgrade to a newer version of the package.
The current upgrade strategy is simple: If the new app is healthy, the old app is removed. There is no rolling upgrade option. All new apps are deployed and checked for health. Then any previous versions are removed. More flexible upgrade strategies are planned in a future release of Skipper.
You can now curl the greeting endpoint and the about endpoint, as shown (with its output) in the following example:
$ curl http://localhost:8100/greeting
yo
$ curl http://localhost:8100/about
Hello World v1.0.1.RELEASEYou can also view the endpoints in your browser.
The list command shows you the current DEPLOYED and DELETED releases for every release name.
In this case there, is just one entry, as you can see with the release list command, as follows:
skipper:>release list

╚═══════════════╧═══════╧═════════════╧════════╧══════════╧═════════╧═════════╧════════════════════════════════════════════════════╝You can get the full history of the release by using the history command, as shown (with its output) in the following example:
skipper:>release history --release-name helloworldlocal
╔═══════╤════════════════════════════╤════════╤════════════╤═══════════════╤════════════════╗

╚═══════╧════════════════════════════╧════════╧════════════╧═══════════════╧════════════════╝To see what changed, you can look at the Skipper manifest for each release by using the manifest get command, as shown (with its output) in the following example:
skipper:>manifest get --release-name helloworldlocal --release-version 2
---
# Source: helloworld.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: helloworld
type: demo
spec:

applicationProperties:
server.port: 8100
endpoints.sensitive: false
helloworld.greeting: yo
deploymentProperties:
spring.cloud.deployer.memory: 2048m
spring.cloud.deployer.count: 1The following example shows the manifest get command and its output for version 1:
skipper:>manifest get --release-name helloworldlocal --release-version 1
---
# Source: helloworld.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: helloworld

resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE
applicationProperties:
server.port: 8099
deploymentProperties:(A manifest diff command is coming in a future release.)
Now we can use the rollback command to deploy an older version of the application.
Since we have the manifest for that version, we have all we need to redeploy an earlier release, as shown (with its output) in the following example:
skipper:>release rollback --release-name helloworldlocal --release-version 1
helloworldlocal has been rolled back. Now at version v3.
The history now shows a new v3 version, even though it is identical in terms of app behavior to the v1 version.
|
The release history command shows all the versions that have been deployed, as shown (with its output) in the following example:
skipper:>release history --release-name helloworldlocal
╔═══════╤════════════════════════════╤════════╤════════════╤═══════════════╤════════════════╗

╚═══════╧════════════════════════════╧════════╧════════════╧═══════════════╧════════════════╝You can now curl the greeting endpoint and see the output of each endpoint, as follows:
$ curl http://localhost:8099/greeting
Hello World!
$ curl http://localhost:8099/about
Hello World v1.0.0.RELEASE9. Cloud Foundry
First, follow the instructions in the section Installing on Cloud Foundry to deploy the Skipper Server to Cloud Foundry.
When you start the Skipper shell, by default, it tries to look for the Skipper server on the same (local) machine.
To specify the Skipper server that is running on Cloud Foundry, provide the serverUrl when launching the shell or use the config command after the shell has started.
The following example provides the serverUrl:
java -jar spring-cloud-skipper-shell-2.0.0.M2.jar --spring.cloud.skipper.client.serverUri=https://mlp-skipper.cfapps.io/apiThe following example uses config:
skipper:>skipper config --uri https://mlp-skipper.cfapps.io/api
Successfully targeted https://mlp-skipper.cfapps.io/apiThe repo list command shows the experimental and local repositories, since they are configured by default.
The local repository is where you can upload new packages.
The experimental repository has a few "hello world" applications to help get you started.
The following example shows the repo list command and the output of our example:
skipper:>repo list
╔════════════╤═══════════════════════════════════════════════════════════╤═════╤═════╗
║ Name │ URL │Local│Order║
╠════════════╪═══════════════════════════════════════════════════════════╪═════╪═════╣

╚════════════╧═══════════════════════════════════════════════════════════╧═════╧═════╝
Above example assumes that experimental repository has been added to the server configuration. More about
working with repositories can be found from Repositories.
|
The following example shows the package search command and the output of our example:
skipper:>package search
╔═════════════════╤═══════╤════════════════════════════════════════════════════════════════════════════════╗
║ Name │Version│ Description ║
╠═════════════════╪═══════╪════════════════════════════════════════════════════════════════════════════════╣

║helloworld-docker│1.0.1 │The app has two endpoints, /about and /greeting in Portuguese. Docker resource.║
║helloworld-docker│1.0.0 │The app has two endpoints, /about and /greeting in English. Docker resource. ║
╚═════════════════╧═══════╧════════════════════════════════════════════════════════════════════════════════╝The command platform list shows the platforms with which the server has been configured, as shown (with its output) in the following example:
╔════╤════════════╤═════════════════════════════════════════════════════════════════════════╗
║Name│ Type │ Description ║
╠════╪════════════╪═════════════════════════════════════════════════════════════════════════╣
║pws │cloudfoundry│org = [scdf-ci], space = [space-mark], url = [https://api.run.pivotal.io]║
╚════╧════════════╧═════════════════════════════════════════════════════════════════════════╝In the preceding example, there is only one Cloud Foundry platform.
Disabling the local platform during the installation process (by setting the enableLocalPlatform property to false) caused the default local platform to not appear.
Now we can install the Hello World app (specifically, the maven based artifact).
The following example shows the package install command (with its output) that we use to install the Hello World application:
skipper:>package install --release-name helloworldpcf --package-name helloworld --package-version 1.0.0 --platform-name pws --properties spec.deploymentProperties.spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.io
Released helloworldpcf. Now at version v1.The spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.io deployment property is set so that, when different versions of this application are deployed, they have the same HTTP route.
Because the default value of that shell option is default`he `--platform-name pws, we used the command option.
When installing Skipper, you can register a platform under the name default, but it is a best practice to specify the target platform name.
You can monitor the progress of the deployment by using the release status command, as shown (with its output) in the following example:
skipper:>release status --release-name helloworldpcf
╔═══════════════╤════════════════════════════════════════════════╗
║Last Deployed │Thu Jan 18 13:18:44 EST 2018 ║
║Status │DEPLOYED ║
║Platform Status│The applications are being deployed. ║
║ │[helloworldpcf-helloworld-v1], State = [partial]║
╚═══════════════╧════════════════════════════════════════════════╝Eventually, the Platform Status says, All applications have been successfully deployed.
The DEPLOYED status in the preceding example indicates that Skipper has told the platform to deploy.
Skipper does not keep track of the intermediate states 'deploying' or 'deleting'.
The platform status provides finer-grained status information.
|
The cf apps command now has a new listing for this deployed application, as shown (with its output) in the following example:
$ cf apps
Getting apps in org scdf-ci / space space-mark as [email protected]...
OK
name requested state instances memory disk urls
helloworldpcf-helloworld-v1 started 1/1 1G 1G helloworldpcf.cfapps.ioYou can now curl the greeting endpoint and the about endpoint, as shown in the following example:
$ curl http://helloworldpcf.cfapps.io/greeting
Hello World!
$ curl http://helloworldpcf.cfapps.io/about
Hello World v1.0.0.RELEASEThe name of the application is based on the <release-name>-<package-name>-v<incrementing-counter> convention.
Also note that we specified a route for this application that is different than the application’s name.
The deployment property spring.cloud.deployer.cloudfoundry.route is set to something that does not change across the deployment of different versions of this application — in this case, helloworldpcf.cfapps.io.
The package provides a means to template the application version, application properties, and deployment properties that are used to deploy the application to Cloud Foundry.
The manifest get command shows the final YAML file which is passed off to the Spring Cloud Deployer Library, as shown (with its output) in the following example:
skipper:>manifest get --release-name helloworldpcf
---
# Source: helloworld.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: helloworld
type: demo
spec:
resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE
applicationProperties:
deploymentProperties:
spring.cloud.deployer.cloudfoundry.route: helloworldpcf.cfapps.ioThe manifest format is inspired by the Kubernetes Resource file format. By looking at the manifest, you can see which Maven artifact was used and which properties were set before the final push to Cloud Foundry. A future release of Skipper will use the metadata values to support searching for releases based on those values.
Since it is somewhat awkward to specify multiple flattened-out YAML values for the --properties argument in the shell, you can also specify the location of a YAML file when installing or upgrading.
In the next example, we use a YAML file, named helloworld-upgrade.yml, to update the release.
This application contains a Spring Boot @ConfigurationProperty named helloworld.greeting, so we set that, along with a standard Spring Boot property: endpoints.sensitive=false.
We also bump the memory up to 2G from the default 1G.
The contents of the helloworld-upgrade.yml file follows:
spec:
applicationProperties:
endpoints.sensitive: false
helloworld.greeting: yo
deploymentProperties:
spring.cloud.deployer.cloudfoundry.route: helloworldpcf.cfapps.io
spring.cloud.deployer.memory: 2048mNow you can run the release upgrade command, as shown (with its output) in the following example:
skipper:>release upgrade --release-name helloworldpcf --package-name helloworld --package-version 1.0.0 --file /home/mpollack/helloworld-upgrade.yml
helloworldpcf has been upgraded. Now at version v2.The preceding example starts another instance of the hello world application, and Skipper determines when it can stop the instance of the previous instance.
If you do not specify --package-version, it picks the latest version of the helloworld package.
You do not need to specify the --platform-name, as it is always where the current application was deployed.
The following example shows the cf apps command and its output:
$ cf apps
Getting apps in org scdf-ci / space space-mark as [email protected]...
OK
name requested state instances memory disk urls
helloworldpcf-helloworld-v1 started 1/1 1G 1G helloworldpcf.cfapps.io
helloworldpcf-helloworld-v2 stopped 0/1 2G 1G helloworldpcf.cfapps.ioThe following example shows the cf routes command and its output:
$ cf routes
Getting routes for org scdf-ci / space space-mark as [email protected] ...
space host domain port path type apps service
space-mark helloworldpcf cfapps.io helloworldpcf-helloworld-v1,helloworldpcf-helloworld-v2At this point, Skipper is checking the health of the new application.
The default health checks whether the HTTP port of the application is open.
There is a customization in Skipper that influences the way the health check is performed.
The spring.cloud.skipper.server.strategies.healthcheck.timeoutInMillis property is the maximum time the upgrade process waits for a healthy app.
The default value is 5 minutes.
Skipper fails the deployment if it is not healthy within that time.
The spring.cloud.skipper.server.strategies.healthcheck.sleepInMillis property is how long to sleep between health checks.
The current upgrade strategy is very simple: If the new app is healthy, the old app is removed. There is not a rolling upgrade option, all new apps are deployed, checked for health, and then previous versions removed. More flexible upgrade strategies are planned in a future release.
You can now curl the greeting endpoint and the about endpoint, as shown in the following example:
$ curl http://helloworldpcf.cfapps.io/greeting
yo
$ curl http://helloworldpcf.cfapps.io/about
Hello World v1.0.0.RELEASEThe release list command shows the current DEPLOYED and DELETED releases for every release name.
In the following example from the sample application, there is only one entry, as shown in the following example:
╔═════════════╤═══════╤══════════════════╤════════╤═══════════╤═══════════╤══════════╤════════════════════════════════════════╗

╚═══════╧════════════════════════════╧════════╧════════════╧═══════════════╧════════════════╝A more typical upgrade process is not to change application properties but to change the version of the application because the code has changed.
In the following example, we now upgrade the release to use a new Maven artifact, version 1.0.1, which also corresponds to version 1.0.1 of the helloworld Skipper package.
In this case, we do not add any additional properties other than the route.
The following example shows the release upgrade command (with its update) to deploy version 1.0.1:
skipper:>release upgrade --release-name helloworldpcf --package-name helloworld --package-version 1.0.1 --properties spec.deploymentProperties.spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.io
helloworldpcf has been upgraded. Now at version v3.Note that the current release’s property values, such as using 2G or the greeting being yo are not carried over.
A future release will introduce a --reuse-properties command that will carry the current release properties over to the next release to be made.
You can monitor the status of the upgrade by using the status command, as shown (with its output) in the following example:
skipper:>release status --release-name helloworldpcf

Hello World v1.0.0.RELEASE10. Kuberenetes
In this example, we run the Skipper server on the local machine and deploy to minikube, which also runs on the local machine.
| The upgrade approach in 1.02 does not correctly handle the routing of HTTP traffic between versions, so the following representation may not be exactly accurate. |
The Spring Cloud Deployer for Kubernetes creates a service, a replication controller, and a pod for the app (or, optionally, a deployment). This is not an issue for apps that communicate over Messaging middleware and will be addressed in a future release.
Start the Skipper server with the --spring.config.additional-location=skipper.yml option. The YAML content follows:
spring:
cloud:
skipper:
server:
enableLocalPlatform: false
platform:
kubernetes:
accounts:
minikube:
namespace: default
The repo list command shows the experimental and local repositories, since they are configured by default, as follows:
skipper:>repo list

╚═════════════════╧═══════╧════════════════════════════════════════════════════════════════════════════════╝The platform list command shows which platforms the server has been configured with — in this case, one Kubernetes namespace.
Disabling the local platform by setting the enableLocalPlatform property to false causes the default local platform to not appear.
skipper:>platform list

╚════════╧══════════╧══════════════════════════════════════════════════════════════════════════════════════╝Now we can install the Hello World app (specifically, the Docker-based artifact), as follows:
skipper:>package install --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.0 --platform-name minikube --properties spec.deploymentProperties.spring.cloud.deployer.kubernetes.createNodePort=32123
Released helloworldk8s. Now at version v1.We use the --platform-name minikube command option, because the default value of that shell option is default.
You can register a platform under the default name when installing Skipper, but it is a best practice to specify the target platform name.
You can monitor the process by using the release status command, as follows:
skipper:>release status --release-name helloworldk8s
╔═══════════════╤══════════════════════════════════════════════════════════════════════════════════════════════════╗
║Last Deployed │Wed Oct 25 17:34:24 EDT 2017 ║

║ │[helloworldk8s-helloworld-docker-v1], State = [helloworldk8s-helloworld-docker-v1-cch68=deploying]║
╚═══════════════╧══════════════════════════════════════════════════════════════════════════════════════════════════╝Eventually, the Platform Status says, All applications have been successfully deployed.
Note that the DEPLOYED status in the preceding example indicates that Skipper has told the platform to deploy.
Skipper does not keep track of the intermediate states ('deploying' or 'deleting').
A kubectl pods command now shows a new listing for this deployed application, as follows:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
helloworldk8s-helloworld-docker-v1-g8j39 0/1 Running 0 37s
$ kubectl get service

kubernetes 10.0.0.1 <none> 443/TCP 57mTo get the URL of this app on minikube, use the minikube service command, as follows:
$ minikube service --url helloworldk8s-helloworld-docker-v1
http://192.168.99.100:32123You can now curl the greeting endpoint and the about endpoint, as shown in the following example:
$ curl http://192.168.99.100:32123/greeting
Hello World!
$ curl http://192.168.99.100:32123/about
Hello World v1.0.0.RELEASEThe name of the application is based on the following convention: <release-name>-<package-name>-v<incrementing-counter>.
Future releases will change this convention to correctly handle routing.
The package provides a means to template the application version, application properties, and deployment properties that are used to deploy the application to Kubernetes.
The manifest get command shows the final YAML file, which is passed off to the Spring Cloud Deployer Library, as shown (with its output) in the following example:
skipper:>manifest get --release-name helloworldk8s
---
# Source: template.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: helloworld-docker
spec:
resource: docker:springcloud/spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE
applicationProperties:
deploymentProperties:
spring.cloud.deployer.kubernetes.createNodePort: 32123The format of the is inspired by the Kubernetes Resource file format. By looking at the manifest, you can see which Docker images were used and which properties were set before the final push to Kubernetes. A future release of Skipper will use the metadata values to support searching for releases based on those values.
Since it is somewhat awkward to specify multiple flattened out YAML values for the --properties argument in the shell, you can also specify the location of a YAML file when installing or upgrading.
We use a YAML file when we update the release.
This application contains a Spring Boot
@ConfigurationProperty named helloworld.greeting, so we set that, along with a standard Spring Boot property: endpoints.sensitive=false. We also bump the memory down to 768m from the default 1G.
The following listing shows all the settings:
spec:
applicationProperties:
endpoints.sensitive: false
helloworld.greeting: yo
deploymentProperties:
spring.cloud.deployer.kubernetes.createNodePort: 32124
spring.cloud.deployer.memory: 768mThe following example shows the release upgrade command and its output:
skipper:>release upgrade --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.0 --file /home/mpollack/helloworld-upgrade-k8s.yml
helloworldk8s has been upgraded. Now at version v2.The preceding command starts another instance of the hello world application.
If you do not specify --package-version, it picks the latest version of the helloworld-docker package.
You do not need to specify the --platform-name as it is always where the current application was deployed.
The following example shows the kubectl get all command and its output:
$ kubectl get all
NAME READY STATUS RESTARTS AGE
po/helloworldk8s-helloworld-docker-v1-g8j39 1/1 Running 0 2m
po/helloworldk8s-helloworld-docker-v2-jz85l 0/1 Running 0 50s

svc/helloworldk8s-helloworld-docker-v2 10.0.0.154 <nodes> 8080:32124/TCP 51s
svc/kubernetes 10.0.0.1 <none> 443/TCP 59mAt this point, Skipper is looking to see if the health endpoint of the Boot application is OK.
The spring.cloud.skipper.server.strategies.healthcheck.timeoutInMillis property sets the maximum time the upgrade process waits for a healthy app.
The default value is 5 minutes.
Skipper fails the deployment if it is not healthy within that time.
The spring.cloud.skipper.server.strategies.healthcheck.sleepInMillis property sets how long to sleep between health checks.
The current upgrade strategy is simple: If the new app is healthy, the old app is removed. There is not a rolling upgrade option. All new apps are deployed and checked for health. Then any previous versions are removed. Future releases will have more flexible upgrade strategies, along with the introduction of the Spring Cloud State Machine project to orchestrate the update process.
You can now curl the greeting endpoint and the about endpoint, as follows:
$ curl http://192.168.99.100:32124/greeting
yo
$ curl http://192.168.99.100:32124/about
Hello World v1.0.0.RELEASEThe release list command shows the current DEPLOYED and DELETED release for every release name.
In the following example, there is only one entry:
skipper:>release list

A more typical upgrade process is not to change application properties but to change the version of the application because the code has changed.
We can now upgrade the release to use a new Docker artifact, version 1.0.1, which also corresponds to version 1.0.1 of the helloworld Skipper package.
In the following example, we do not add any additional properties other than NodePort:
skipper:>release upgrade --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.1 --properties spec.deploymentProperties.spring.cloud.deployer.kubernetes.createNodePort=32125
Released helloworldk8s. Now at version v3.Note that the the current release’s property values, such as using 2G RAM or the greeting being yo, are not carried over.
A future release will introduce a --reuse-properties command option that will carry the current release properties over to the next release to be made.
You can monitor the status of the upgrade by using the status command, as shown (with its output) in the following example:
skipper:>release status --release-name helloworldk8s

This section is the "'three-hour tour'" of Skipper. It describes how to configure and use the main feature set of Skipper in detail. We will cover the shell, platforms, packages, and repositories.
Feel free to reach out on Gitter for help and ask questions on Stack Overflow. Issues can be filed on Github issues.
12. Skipper Shell
The shell is based on the Spring Shell project.
Two of the shell’s best features are tab-completion and colorization of commands.
Use the 'help' command or the --help argument when starting the shell to get help information.
The output of using the --help argument follows:
Skipper Options:
--spring.cloud.skipper.client.serverUri=<uri> Address of the Skipper Server [default: http://localhost:7577].
--spring.cloud.skipper.client.username=<USER> Username of the Skipper Server [no default].
--spring.cloud.skipper.client.password=<PASSWORD> Password of the Skipper Server [no default].
--spring.cloud.skipper.client.credentials-provider-command=<COMMAND> Executes an external command which must return an OAuth Access Token [no default].
--spring.cloud.skipper.client.skip-ssl-validation=<true|false> Accept any SSL certificate (even self-signed) [default: no].
--spring.shell.historySize=<SIZE> Default size of the shell log file [default: 3000].
--spring.shell.commandFile=<FILE> Skipper Shell executes commands read from the file(s) and then exits.
--help This message.12.1. Shell Modes
The shell can be started in either interactive or non-interactive mode.
In the case of the non-interactive mode, command line arguments are executed as Skipper commands, and then the shell exits.
If there are any arguments that do not have the prefix spring.cloud.skipper.client, they are considered as skipper commands to execute.
Consider the following example:
java -jar spring-cloud-skipper-shell-2.0.0.M2.jar --spring.cloud.skipper.client.serverUri=http://localhost:9123/apiThe preceding example brings up the interactive shell and connects to localhost:9123/api.
Now consider the following command:
$ java -jar spring-cloud-skipper-shell-2.0.0.M2.jar --spring.cloud.skipper.client.serverUri=http://localhost:9123/api searchThe preceding command connects to localhost:9123/api, executes the search command, and then exits.
A more common use case would be to update a package from within a CI job — for example, in a Jenkins Stage, as shown in the following example:
stage ('Build') {
steps {
checkout([
$class: 'GitSCM',
branches: [
[name: "*/master"]
],
userRemoteConfigs: [
[url: "https://github.com/markpollack/skipper-samples.git"]
]
])
sh '''
VERSION="1.0.0.M1-$(date +%Y%m%d_%H%M%S)-VERSION"
mvn org.codehaus.mojo:versions-maven-plugin:2.3:set -DnewVersion="${VERSION}"
mvn install
java -jar /home/mpollack/software/skipper.jar upgrade --package-name helloworld --release-name helloworld-jenkins --properties version=${VERSION}
'''
}
}13. Platforms
Skipper supports deploying to multiple platforms.
The platforms included are Local, Cloud Foundry, and Kubernetes.
For each platform, you can configure multiple accounts.
Each account name must be globally unique across all platforms.
Usually, different accounts correspond to different orgs or spaces for Cloud Foundry and to different namespaces for a single Kubernetes cluster.
Platforms are defined by using Spring Boot’s Externalized Configuration feature.
To simplify the getting started experience, if a local platform account is not defined in your configuration, Skipper creates a local deployer implementation named default.
You can make use of the Encryption and Decryption features of Spring Cloud Config as one way to secure credentials.
Distinct from where Skipper deploys the application, you can also run the Skipper server itself on a platform. Installation on other platforms is covered in the Installation section.
The following example YAML file shows configuration of all three platforms:
spring:
cloud:
skipper:
server:
platform:
local:
accounts:
localDevDebug:
javaOpts: "-Xdebug"
cloudfoundry:
accounts:
cf-dev:
connection:
url: https://api.run.pivotal.io
org: scdf-ci
space: space-mark
domain: cfapps.io
username: <your-username>
password: <your-password>
skipSslValidation: false
deployment:
deleteRoutes: false
kubernetes:
accounts:
minikube:
namespace: default
The properties available for each platform can be found in the following classes:
-
CloudFoundryDeploymentProperties for
deployment:and CloudFoundryConnectionProperties for theconnection:.
14. Packages
Packages contain all the necessary information to install your application or group of applications. The approach to describing the applications is to use a YAML file that provides all the necessary information to help facilitate searching for your application hosted in a Package Registry and to install your application to a platform.
To make it easy to customize a package, the YAML files are templated.
The final version of the YAML file, with all values substituted, is known as the release manifest.
Skipper currently understands how to deploy applications based off a YAML file that contains the information needed for
a Spring Cloud Deployer or Cloud Foundry implementation to deploy an application.
It describes where to find the application (an HTTP, Maven or Docker location), application properties (think Spring
Boot @ConfigurationProperties), and deployment properties (such as how much memory to use).
14.1. Package Format
A package is a collection of YAML files that are zipped up into a file with the following naming convention:
[PackageName]-[PackageVersion].zip (for example: mypackage-1.0.0.zip).
A package can define a single application or a group of applications.
14.1.1. Single Application
The single application package file, mypackage-1.0.0.zip, when unzipped, should have the following directory
structure:
mypackage-1.0.0
├── package.yml
├── templates
│ └── template.yml
└── values.ymlThe package.yml file contains metadata about the package and is used to support Skipper’s search functionality.
The template.yml file contains placeholders for values that are specified in the values.yml file.
When installing a package, placeholder values can also be specified, and they would override the values in the
values.yml file.
The templating engine that Skipper uses is JMustache.
The YAML files can have either .yml or .yaml extensions.
The helloworld-1.0.0.zip or helloworld-docker-1.0.0.zip files are good examples to use as a basis to create your own package "'by hand'".
The source code for the helloworld sample can be found here.
14.1.2. Multiple Applications
A package can contain a group of applications bundled in it. In those cases, the structure of the package would resemble the following:
mypackagegroup-1.0.0
├── package.yml
├── packages
│ ├── app1
│ │ ├── package.yml
│ │ ├── templates
│ │ │ └── log.yml
│ │ └── values.yml
│ └── app2
│ ├── package.yml
│ ├── templates
│ │ └── time.yml
│ └── values.yml
└── values.ymlIn the preceding example, the mypackagegroup still has its own package.yml and values.yml to specify the package
metadata and the values to override. All the applications inside the mypackagegroup are considered to be
sub-packages and follow a package structure similar to the individual packages. These sub packages need to be specified
inside the packages directory of the root package, mypackagegroup.
The ticktock-1.0.0.zip file is a good example to use as a basis for creating your own package 'by-hand'.
|
Packages with template kind CloudFoundryApplication currently doesn’t support multiple applications format. |
14.2. Package Metadata
The package.yml file specifies the package metadata.
A sample package metadata would resemble the following:
# Required Fields apiVersion: skipper.spring.io/v1 kind: SkipperPackageMetadata name: mypackage version: 1.0.0 # Optional Fields packageSourceUrl: https://github.com/some-mypackage-project/v1.0.0.RELEASE packageHomeUrl: http://some-mypackage-project/ tags: skipper, mypackage, sample maintainer: https://github.com/maintainer description: This is a mypackage sample.
Required Fields:
-
apiVersion: The Package Index spec version this file is based on. -
kinds: What type of package system is being used. -
name: The name of the package. -
version: The version of the package.
|
Currently only supported kind is SkipperPackageMetadata. |
Optional Fields:
-
packageSourceUrl: The location of the source code for this package. -
packageHomeUrl: The home page of the package. -
tags: A comma-separated list of tags to be used for searching. -
maintainer: Who maintains this package. -
description: Free-form text describing the functionality of the package — generally shown in search results. -
sha256: The hash of the package binary (not yet enforced). -
iconUrl: The URL for an icon to show for this package. -
origin: Free-form text describing the origin of this package — for example, your company name.
|
Currently, the package search functionality is only a wildcard match against the name of the package. |
A Package Repository exposes an index.yml file that contains multiple metadata documents and that uses the standard three dash notation --- to separate the documents — for example, index.yml.
14.3. Package Templates
Currently, two type of applications are supported. One having SpringCloudDeployerApplication kind, which means the
applications can be deployed into the target platforms only by using their corresponding Spring Cloud Deployer
implementations (CF, Kubernetes Deployer, and so on). Other is having CloudFoundryApplication kind, which means the
applications are directly deployed into Cloud Foundry using its manifest support.
14.3.1. Spring Cloud Deployer
The template.yml file has a package structure similar to that of the following example:
mypackage-1.0.0
├── package.yml
├── templates
│ └── template.yml
└── values.yml|
Actual template file name doesn’t matter and you can have multiple template files. These just need to be inside of a
|
# template.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: mypackage
type: sample
spec:
resource: maven://org.mysample:mypackage
resourceMetadata: maven://org.mysample:mypackage:jar:metadata:{{spec.version}}
version: {{spec.version}}
applicationProperties:
{{#spec.applicationProperties.entrySet}}
{{key}}: {{value}}
{{/spec.applicationProperties.entrySet}}
deploymentProperties:
{{#spec.deploymentProperties.entrySet}}
{{key}}: {{value}}
{{/spec.deploymentProperties.entrySet}}The apiVersion, kind, and spec.resource are required.
The spec.resource and spec.version define where the application executable is located. The spec.resourceMetadata
field defines where a Spring Boot Configuration metadata
jar is located that contains the configuration properties of the application. This is either a Spring Boot uber jar
hosted under a HTTP endpoint or a Maven or Docker repository. The template placeholder {{spec.version}} exists so that
the version of a specific application can be easily upgraded without having to create a new package .zip file.
The resource is based on http:// or maven:// or docker:. The format for specifying a resource follows documented
types in Resources.
14.3.2. Cloud Foundry
The template.yml file has a package structure similar to that of the following example:
mypackage-1.0.0
├── package.yml
├── templates
│ └── template.yml
└── values.ymltemplate.yml commonly has content similar to the following:
|
Actual template file name doesn’t matter and you can have multiple template files. These just need to be inside of a
|
# template.yml
apiVersion: skipper.spring.io/v1
kind: CloudFoundryApplication
spec:
resource: maven://org.mysample:mypackage
version: {{spec.version}}
manifest:
{{#spec.manifest.entrySet}}
{{key}}: {{value}}
{{/spec.manifest.entrySet}}Where values could for example be something like:
# values.yml
spec:
version: 1.0.0
manifest:
memory: 1024
disk-quota: 1024Possible values of a spec.manifest are:
| Key | Value | Notes |
|---|---|---|
|
(String) |
buildpack attribute as is. |
|
(String) |
command attribute as is. |
|
(String or Integer) |
memory attribute as is if type is Integer, String is converted using same format in a CF, like |
|
(String or Integer) |
disk_quota attribute as is if type is Integer, String is converted using same format in a CF, like |
|
(Integer) |
timeout attribute as is. |
|
(Integer) |
instances attribute as is. |
|
(Boolean) |
no-hostname attribute as is. |
|
(Boolean) |
no-route attribute as is. |
|
(Boolean) |
random-route attribute as is. |
|
(String) |
health-check-type having possible values of |
|
(String) |
health-check-http-endpoint attribute as is. |
|
(String) |
stack attribute as is. |
|
(List<String>) |
services attribute as is. |
|
(List<String>) |
domains attribute as is. |
|
(List<String>) |
hosts attribute as is. |
|
(Map<String,Object>) |
env attribute as is. |
|
Remember that when a value is given from a command-line, replacement happens as is defined in a template. Using a template
format |
The resource is based on http:// or maven:// or docker:. The format for specifying a resource follows documented
types in Resources.
14.3.3. Resources
This section contains resource types currently supported.
HTTP Resources
The following example shows a typical spec for HTTP:
spec:
resource: http://example.com/app/hello-world
version: 1.0.0.RELEASEThere is a naming convention that must be followed for HTTP-based resources so that Skipper can assemble a full URL from the resource and version field and also parse the version number given the URL.
The preceding spec references a URL at example.com/app/hello-world-1.0.0.RELEASE.jar.
The resource and version fields should not have any numbers after the - character.
Docker Resources
The following example shows a typical spec for Docker:
spec:
resource: docker:springcloud/spring-cloud-skipper-samples-helloworld
version: 1.0.0.RELEASEThe mapping to docker registry names follows:
spec:
resource: docker:<user>/<repo>
version: <tag>Maven Resources
The following example shows a typical spec for Maven:
spec: resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE version: 1.0.0.RELEASE
The mapping to Maven artifact names follows
spec:
resource: maven://<maven-group-name>:<maven-artifact-name>
version:<maven-version>There is only one setting to specify with Maven repositories to search. This setting applies across all platform accounts. By default, the following configuration is used:
maven:
remoteRepositories:
springRepo: https://repo.spring.io/libs-snapshotYou can specify other entries and also specify proxy properties.
This is currently best documented here.
Essentially, this needs to be set as a property in your launch properties or manifest.yml (when pushing to PCF), as follows:
# manifest.yml
...
env:
SPRING_APPLICATION_JSON: '{"maven": { "remote-repositories": { "springRepo": { "url": "https://repo.spring.io/libs-snapshot"} } } }'
...The metadata section is used to help search for applications after they have been installed. This feature will be made available in a future release.
The spec contains the resource specification and the properties for the package.
The resource represents the resource URI to download the application from.
This would typically be a Maven co-ordinate or a Docker image URL.
The SpringCloudDeployerApplication kind of application can have applicationProperties and deploymentProperties
as the configuration properties.
The application properties correspond to the properties for the application itself.
The deployment properties correspond to the properties for the deployment operation performed by Spring Cloud Deployer implementations.
|
The |
14.4. Package Values
The values.yml file contains the default values for any of the keys specified in the template files.
For instance, in a package that defines one application, the format is as follows:
version: 1.0.0.RELEASE
spec:
applicationProperties:
server.port: 9090If the package defines multiple applications, provide the name of the package in the top-level YML section to scope the
spec section. Consider the example of a multiple application package with the following layout:
ticktock-1.0.0/
├── packages
│ ├── log
│ │ ├── package.yml
│ │ └── values.yml
│ └── time
│ ├── package.yml
│ └── values.yml
├── package.yml
└── values.ymlThe top-level values.yml file might resemble the following:
#values.yml
hello: world
time:
appVersion: 1.3.0.M1
deployment:
applicationProperties:
log.level: WARN
trigger.fixed-delay: 1
log:
deployment:
count: 2
applicationProperties:
log.level: WARN
log.name: skipperloggerThe preceding values.yml file sets hello as a variable available to be used as a placeholder in the
packages\log\values.yml file and the packages\time\values.yml. However, the YML section under time: is applied
only to the packages\time\values.yml file and the YML section under log: is applied only to the
packages\log\values.yml file.
14.5. Package Upload
After creating the package in the structure shown in the previous section, we can compress it in a zip file with the following naming scheme: [PackageName]-[PackageVersion].zip (for example, mypackage-1.0.0.zip).
For instance, the package directory would resemble the following before compression:
mypackage-1.0.0 ├── package.yml ├── templates │ └── template.yml └── values.yml
The zip file can be uploaded into one of the local repositories of the Skipper server.
By default, the Skipper server has a local repository with the name, local.
By using the Skipper shell, we can upload the package zip file into the Skipper server’s local repository, as follows:
skipper:>package upload --path /path-to-package/mypackage-1.0.0.zip
Package uploaded successfully:[mypackage:1.0.0]If no --repo-name is set, the upload command uses local as the repository to upload.
We can then use the package list or package search command to see that our package has been uploaded, as shown (with its output) in the following example:
skipper:>package list
╔═════════════════╤═══════╤════════════════════════════════════════════════════════════════════════════════╗
║ Name │Version│ Description ║
╠═════════════════╪═══════╪════════════════════════════════════════════════════════════════════════════════╣
║helloworld │1.0.0 │The app has two endpoints, /about and /greeting in English. Maven resource. ║
║helloworld │1.0.1 │The app has two endpoints, /about and /greeting in Portuguese. Maven resource. ║
║helloworld-docker│1.0.0 │The app has two endpoints, /about and /greeting in English. Docker resource. ║
║helloworld-docker│1.0.1 │The app has two endpoints, /about and /greeting in Portuguese. Docker resource.║
║mypackage │1.0.0 │This is a mypackage sample ║
╚═════════════════╧═══════╧════════════════════════════════════════════════════════════════════════════════╝14.6. Creating Your Own Package
In this section, we create a package that can be deployed by using Spring Cloud Deployer implementations.
For this package, we are going to create a simple package and upload it to our local machine.
To get started creating your own package, create a folder following a naming convention of [package-name]-[package-version]. In our case, the folder name is demo-1.0.0.
In this directory, create empty files named values.yml and package.yml and create a templates directory.
In the templates directory, create an empty file named template.yml.
Go into the package.yml where we are going to specify the package metadata. For this app, we fill only the minimum values possible, as shown in the following example:
# package.yml apiVersion: skipper.spring.io/v1 kind: SkipperPackageMetadata name: demo version: 1.0.0 description: Greets the world!
Ensure that your name and version matches the name and version in your folder name, or you get an error.
|
Next, open up your templates/template.yml file.
Here, we are going to specify the actual information about your package and, most importantly, set default values.
In the template.yml, copy the template for the kind SpringCloudDeployerApplication from the preceding sample.
Your resulting template.yml file should resemble the following:
# templates/template.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: demo
spec:
resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld
version: {{version}}
applicationProperties:
{{#spec.applicationProperties.entrySet}}
{{key}}: {{value}}
{{/spec.applicationProperties.entrySet}}
deploymentProperties:
{{#spec.deploymentProperties.entrySet}}
{{key}}: {{value}}
{{/spec.deploymentProperties.entrySet}}
The preceding example file specifies that our application name is demo and finds our package in Maven.
Now we can specify the version, applicationProperties, and deploymentProperties in our values.yml, as follows:
# values.yml
# This is a YAML-formatted file.
# Declare variables to be passed into your templates
version: 1.0.0.RELEASE
spec:
applicationProperties:
server.port: 8100
The preceding example sets the version to 1.0.0.RELEASE and also sets the server.port=8100 as one of the application properties.
When the Skipper Package reader resolves these values by merging the values.yml against the template, the resolved values resemble the following:
# hypothetical template.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
name: demo
spec:
resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld
version: 1.0.0.RELEASE
applicationProperties:
server.port: 8100
deploymentProperties:
The reason to use values.yml instead of entering the values directly is that it lets you overwrite the values at run time by using the --file or --properties flags.
We have finished making our file.
Now we have to zip it up.
The easiest way to do is by using the zip -r command on the command line, as follows:
$ zip -r demo-1.0.0.zip demo-1.0.0/ adding: demo-1.0.0/ (stored 0%) adding: demo-1.0.0/package.yml (deflated 14%) adding: demo-1.0.0/templates/ (stored 0%) adding: demo-1.0.0/templates/template.yml (deflated 55%) adding: demo-1.0.0/values.yml (deflated 4%)
Armed with our zipped file and the path to it, we can head to Skipper and use the upload command, as follows:
skipper:>package upload --path /Users/path-to-your-zip/demo-1.0.0.zip Package uploaded successfully:[demo:1.0.0]
Now you can search for it as shown previously and then install it, as follows
skipper:>package install --package-name demo --package-version 1.0.0 --release-name demo Released demo. Now at version v1.
Congratulations! You have now created, packaged, uploaded, and installed your own Skipper package!
15. Repositories
Repositories store package metadata and host package .zip files. Repositores can be local or remote, were local means backed by Skipper’s relational database and remote means a filesystem exposed over HTTP.
When registering a remote registry (for example, the experimental one that is currently not defined by default in addition to one named local`), use the following format:
spring
cloud:
skipper:
server:
package-repositories:
-
name: experimental
url: http://skipper-repository.cfapps.io/repository/experimental
description: Experimental Skipper Repository
repoOrder: 0
-
name: local
url: http://${spring.cloud.client.hostname}:7577
local: true
description: Default local database backed repository
repoOrder: 1
When modifying default configuration you need to re-define everything under spring.cloud.skipper.server.package-repositories.
|
The repoOrder determines which repository serves up a package if one with the same name is registered in two or more repositories.
The directory structure assumed for a remote repository is the registered url value followed by the package name and then the zip file name (for example, skipper-repository.cfapps.io/repository/experimental/helloworld/helloworld-1.0.0.zip for the package helloworld with a version of 1.0.0).
A file named index.yml is expected to be directly under the registered url — for example, skipper-repository.cfapps.io/repository/experimental/index.yml.
This file contains the package metadata for all the packages hosted by the repository.
It is up to you to update the index.yml file "'by hand'" for remote repositories.
'Local' repositories are backed by Skipper’s database. In the Skipper 1.0 release, they do not expose the index.yml or the .zip files under a filesystem-like URL structure as with remote repositories. This feature will be provided in the next version. However, you can upload packages to a local repository and do not need to maintain an index file. See the “Skipper Commands” section for information on creating local repositories.
A good example that shows using a Spring Boot web application with static resources to host a Repository can be found here. This application is currently running under skipper-repository.cfapps.io/repository/experimental.
Installation
16. Installing on a Local Platform
16.1. Local Platform configuration
The following example YAML file configures two local deployer accounts, named localDev and localDevDebug:
spring:
cloud:
skipper:
server:
platform:
local:
accounts:
localDev:
shutdownTimeout: 60
javaOpts: "-Dtest=foo"
localDevDebug:
javaOpts: "-Xdebug"The key-value pairs that follow the name of the account are javaCmd, workingDirectoriesRoot, deleteFilesOnExit, envVarsToInherit, shutdownTimeout, javaOpts, and useSpringApplicationJson.
More information can be found in the JavaDocs for LocalDeployerProperties.
17. Installing on Cloud Foundry
This section contains an example YAML file that configures two Cloud Foundry accounts, named cf-dev and cf-qa.
This is useful on Cloud Foundry if you use the Spring Cloud Config Server to manage Skipper’s configuration properties.
17.1. Cloud Foundry Configuration
You can modify the following sample YML snippet to fit your needs:
spring:
cloud:
skipper:
server:
enableLocalPlatform: false
platform:
cloudfoundry:
accounts:
cf-dev:
connection:
url: https://api.run.pivotal.io
org: myOrg
space: mySpace
domain: cfapps.io
username: [email protected]
password: drowssap
skipSslValidation: false
deployment:
memory: 2048m
disk: 2048m
services: rabbit
deleteRoutes: false
cf-qa:
connection:
url: https://api.run.pivotal.io
org: myOrgQA
space: mySpaceQA
domain: cfapps.io
username: [email protected]
password: drowssap
skipSslValidation: true
deployment:
memory: 1024m
disk: 1024m
services: rabbitQA
deleteRoutes: false
You must set enableLocalPlatform to false so that the local platform deployer is never used.
|
The deleteRoutes deployment setting is false so that “v2” of an application has the same route as “v1”.
Otherwise, undeploying “v1” removes the route.
|
You can also run the Skipper server locally and deploy to Cloud Foundry.
In this case, it is more convenient to specify the configuration in a skipper.yml file and start the server with the --spring.config.additional-location=skipper.yml option.
If you use cf push to deploy Skipper, a Cloud Foundry manifest is more appropriate to use.
You can modify the following sample manifest.yml to fit your needs:
applications:
- name: mlp-skipper
host: mlp-skipper
memory: 1G
disk_quota: 1G
timeout: 180
instances: 1
buildpack: java_buildpack
path: spring-cloud-skipper-server.jar
env:
SPRING_APPLICATION_NAME: mlp-skipper
SPRING_PROFILES_ACTIVE: cloud
JBP_CONFIG_SPRING_AUTO_RECONFIGURATION: '{enabled: false}'
SPRING_CLOUD_SKIPPER_SERVER_ENABLELOCALPLATFORM: false
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_URL: https://api.run.pivotal.io
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_ORG: myOrgQA
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_SPACE: mySpaceQA
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_DOMAIN: cfapps.io
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_USERNAME: [email protected]
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_PASSWORD: drowssap
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_SKIP_SSL_VALIDATION: false
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_DEPLOYMENT_DELETE_ROUTES: false
SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_DEPLOYMENT_SERVICES: rabbitmq
services:
- mysqlboost
In the preceding manifest, we bound the application to the mysqlboost service.
If you do not specify a service, the server uses an embedded database.
|
As of Skipper 2.0, you must disable Spring Auto-reconfiguration and set the profile to cloud.
|
You must set SPRING_CLOUD_SKIPPER_SERVER_ENABLELOCALPLATFORM to false so that the local platform deployer is never used.
|
You must set SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_DEPLOYMENT_DELETE_ROUTES: false so that “v2” of an application has the same route as “v1”.
Otherwise, undeploying “v1” removes the route.
|
You can find information on the deployment properties that you can configure in CloudFoundryDeploymentProperties.
When starting the Skipper shell on your local machine, it tries to connect to the Server at the default location of localhost:7577/api.
Use the shell’s --spring.cloud.skipper.client.serverUri command line option to specify the location of the server.
You can alternatively use the config interactive shell command to set the server location, as follows:
server-unknown:>skipper config --uri https://mlp-skipper.cfapps.io/api
Successfully targeted https://mlp-skipper.cfapps.io/api
skipper:>17.2. Database Connection Pool
As of Skipper 2.0, the Spring Cloud Connector library is no longer used to create the DataSource. The library java-cfenv is now used which allows you to set Spring Boot properties to configure the connection pool.
17.3. Maximum Disk Quota
By default, every application in Cloud Foundry starts with 1G disk quota and this can be adjusted to a default maximum of 2G. The default maximum can also be overridden up to 10G by using Pivotal Cloud Foundry’s (PCF) Ops Manager GUI.
This configuration is relevant for Spring Cloud Skipper because every deployment is composed of applications (typically Spring Boot uber-jar’s), and those applications are resolved from a remote maven repository. After resolution, the application artifacts are downloaded to the local Maven Repository for caching and reuse. With this happening in the background, the default disk quota (1G) can fill up rapidly, especially when we experiment with streams that are made up of unique applications. In order to overcome this disk limitation and depending on your scaling requirements, you may want to change the default maximum from 2G to 10G. Let’s review the steps to change the default maximum disk quota allocation.
From PCF’s Ops Manager, select the “Pivotal Elastic Runtime” tile and navigate to the “Application Developer Controls” tab. Change the “Maximum Disk Quota per App (MB)” setting from 2048 (2G) to 10240 (10G). Save the disk quota update and click “Apply Changes” to complete the configuration override.
17.4. Managing Disk Use
Even when configuring Skipper to use 10G of space, there is the possibility of exhausting
the available space on the local disk.
If you deploy the Skipper by using the default port health check type, you must explicitly monitor the disk space on the server in order to avoid running out space.
If you deploy the server by using the http health check type (see the next example), the server is restarted if there is low disk space.
This is due to Spring Boot’s Disk Space Health Indicator.
You can configure the settings of the Disk Space Health Indicator by using the properties that have the management.health.diskspace prefix.
For version 1.7, we are investigating the use of Volume Services for the server to store .jar artifacts before pushing them to Cloud Foundry.
The following example shows how to deploy the http health check type to an endpoint called /management/health:
---
...
health-check-type: http
health-check-http-endpoint: /management/health18. Installing on Kubernetes
A docker image, named springcloud/spring-cloud-skipper-server, is available for Skipper server in dockerhub.
You can use this image to run the Skipper server in Kubernetes.
18.1. Kuberenetes configuration
The following example YAML file configures two accounts, named k8s-dev and k8sqa, on a Kubernetes cluster.
spring:
cloud:
skipper:
server:
platform:
kubernetes:
accounts:
k8s-dev:
namespace: devNamespace
cpu: 4
k8s-qa:
namespace: qaNamespace
memory: 1024mThe accounts correspond to different namespaces. We are investigating how to support connecting to different Kubernetes clusters.
You can find more information on the deployment properties that you can configure in KubernetesDeployerProperties
19. Database configuration
Spring Cloud Skipper uses a relational database to store metadata. We use Flyway to bootstrap and then migrate the database as the product evolves. We currently provide schemas for the following databases: H2, HSQLDB, MySQL, PostgreSQL, Microsoft SQL Server, Oracle 12, and IBM DB2.
The JDBC drivers for MySQL (through the MariaDB driver), HSQLDB, PostgreSQL, and SQL Server, along the embedded H2 database, are bundled with the server jar. If you use any other database, the corresponding JDBC driver jar needs to be on the classpath of the server. If not specified, the server starts with the embedded in-memory H2 database.
The database properties can be passed as environment variables or command-line arguments to the Server.
Make sure that you configure the correct flyway.schemas for DB2 and SQL Server. Otherwise, Flyway tries to create its schema_version table on the default schema for a connection, which could be different than the schema with which your credentials are associated.
See the Flyway documentation for more options.

Security
By default, the Spring Cloud Skipper server is unsecured and runs on an unencrypted HTTP connection. You can secure your REST endpoints by enabling HTTPS and requiring clients to authenticate using OAuth 2.0
|
By default, the REST endpoints (administration, management and health) do not require authenticated access. |
20. Enabling HTTPS
By default, the REST endpoints use plain HTTP as a transport.
You can switch to HTTPS by adding a certificate to your configuration, as shown in the following skipper.yml example:
server:
port: 8443 (1)
ssl:
key-alias: yourKeyAlias (2)
key-store: path/to/keystore (3)
key-store-password: yourKeyStorePassword (4)
key-password: yourKeyPassword (5)
trust-store: path/to/trust-store (6)
trust-store-password: yourTrustStorePassword (7)| 1 | As the default port is 7577, you may choose to change the port to a more common HTTPs-typical port. |
| 2 | The alias (or name) under which the key is stored in the keystore. |
| 3 | The path to the keystore file. Classpath resources may also be specified, by using the classpath prefix: classpath:path/to/keystore |
| 4 | The password of the keystore. |
| 5 | The password of the key. |
| 6 | The path to the truststore file. Classpath resources may also be specified, by using the classpath prefix: classpath:path/to/trust-store |
| 7 | The password of the trust store. |
You can reference the YAML file using the following parameter: --spring.config.additional-location=skipper.yml
|
| If HTTPS is enabled, it completely replaces HTTP as the protocol over which the REST endpoints interact. Plain HTTP requests then fail. Therefore, you must make sure that you configure the Skipper shell accordingly. |
20.1. Using Self-Signed Certificates
For testing purposes or during development, it might be convenient to create self-signed certificates. To get started, run the following command to create a certificate:
$ keytool -genkey -alias skipper -keyalg RSA -keystore skipper.keystore \
-validity 3650 -storetype JKS \
-dname "CN=localhost, OU=Spring, O=Pivotal, L=Holualoa, ST=HI, C=US" (1)
-keypass skipper -storepass skipper| 1 | CN is the only important parameter here. It should match the domain you are trying to access, e.g. localhost. |
Then add the following to your skipper.yml file:
server:
port: 8443
ssl:
enabled: true
key-alias: skipper
key-store: "/your/path/to/skipper.keystore"
key-store-type: jks
key-store-password: skipper
key-password: skipperThat is all you need for the Skipper Server. Once you start the server, you should be able to access it at https://localhost:8443/. As this is a self-signed certificate, you should hit a warning in your browser. You need to ignore that.
20.2. Self-Signed Certificates and the Shell
By default, self-signed certificates are an issue for the shell. Additional steps are necessary to make the shell work with self-signed certificates. Two options are available:
20.2.1. Add the Self-signed Certificate to the JVM Truststore
In order to use the JVM truststore option, we need to export the previously created certificate from the keystore:
$ keytool -export -alias skipper -keystore skipper.keystore -file skipper_cert -storepass skipperNext, we need to create a truststore which the Shell uses:
$ keytool -importcert -keystore skipper.truststore -alias skipper -storepass skipper -file skipper_cert -nopromptNow you can launch the Skipper shell by using the following JVM arguments:
$ java -Djavax.net.ssl.trustStorePassword=skipper \
-Djavax.net.ssl.trustStore=/path/to/skipper.truststore \
-Djavax.net.ssl.trustStoreType=jks \
-jar spring-cloud-skipper-shell-2.0.0.M2.jar
If you run into trouble establishing a connection over SSL, you can enable additional logging by setting the javax.net.debug JVM argument to ssl.
|
Remember to target the Skipper server with a config command similar to the following:
skipper:>skipper config --uri https://localhost:8443/api20.2.2. Skip Certificate Validation
Alternatively, you can bypass the certification validation by providing the following optional command-line parameter: --spring.cloud.skipper.client.skip-ssl-validation=true.
When you set this command-line parameter, the shell accepts any (self-signed) SSL certificate.
| If possible, you should avoid using this option. Disabling the trust manager defeats the purpose of SSL and makes your site vulnerable to man-in-the-middle attacks. |
21. OAuth 2.0 Security
OAuth 2.0 lets you integrate Spring Cloud Skipper into Single Sign-on (SSO) environments. You can use the following OAuth2 Grant Types:
-
Password: Used by the shell (and the REST integration), so you can login with a username and a password
-
Client Credentials: Retrieve an Access Token directly from your OAuth provider and pass it to the Skipper server in the
AuthorizationHTTP header.
The REST endpoints can be accessed in two ways:
-
Basic Authentication: Uses the Password Grant Type to authenticate with your OAuth2 service.
-
Access Token: Uses the Client Credentials Grant Type
| When you set up authentication, we strongly recommended enabling HTTPS as well, especially in production environments. |
You can turn on OAuth2 authentication by setting environment variables or by adding the following block to skipper.yml:
security:
oauth2:
client:
client-id: myclient (1)
client-secret: mysecret
access-token-uri: http://127.0.0.1:9999/oauth/token
user-authorization-uri: http://127.0.0.1:9999/oauth/authorize
resource:
user-info-uri: http://127.0.0.1:9999/me| 1 | Providing the Client ID in the OAuth Configuration Section activates OAuth2 security. |
You can verify that basic authentication is working properly by using curl, as follows:
$ curl -u myusername:mypassword localhost:7577/
As a result, you should see a list of available REST endpoints.
Besides Basic Authentication, you can also provide an Access Token to access the REST API.
To make that happen, retrieve an OAuth2 Access Token from your OAuth2 provider and then pass that Access Token to the REST API by using the Authorization HTTP header, as follows:
$ curl -H "Authorization: Bearer <ACCESS_TOKEN>" localhost:7577/
21.1. OAuth REST Endpoint Authorization
Spring Cloud Skipper supports the following roles:
-
VIEW: For anything that relates to retrieving state.
-
CREATE: For anything that involves creating, deleting, or mutating the state of the system.
-
MANAGE: For boot management endpoints.
The rules regarding which REST endpoints require which roles are specified in the application.yml of the spring-cloud-skipper-server-core module.
Nonetheless, you can override those, if desired.
The configuration takes the form of a YAML list (as some rules may have precedence over others).
Consequently, you need to copy/paste the whole list and tailor it to your needs (as there is no way to merge lists).
Always refer to your version of application.yml, as the snippet reproduced below may be outdated.
The default rules are as follows:
# About
- GET /api/about => hasRole('ROLE_VIEW')
# AppDeployerDatas
- GET /api/appDeployerDatas => hasRole('ROLE_VIEW')
# Deployers
- GET /api/deployers => hasRole('ROLE_VIEW')
## Releases
- GET /api/releases => hasRole('ROLE_VIEW')
# Status
- GET /api/release/status/** => hasRole('ROLE_VIEW')
# Manifest
- GET /api/release/manifest/** => hasRole('ROLE_VIEW')
# Upgrade
- POST /api/release/upgrade => hasRole('ROLE_CREATE')
# Rollback
- POST /api/release/rollback/** => hasRole('ROLE_CREATE')
# Delete
- DELETE /api/release/** => hasRole('ROLE_CREATE')
# History
- GET /api/release/history/** => hasRole('ROLE_VIEW')
# List
- GET /api/release/list => hasRole('ROLE_VIEW')
- GET /api/release/list/** => hasRole('ROLE_VIEW')
# Packages
- GET /api/packages => hasRole('ROLE_VIEW')
# Upload
- POST /api/package/upload => hasRole('ROLE_CREATE')
# Install
- POST /api/package/install => hasRole('ROLE_CREATE')
- POST /api/package/install/** => hasRole('ROLE_CREATE')
# Delete
- DELETE /api/package/** => hasRole('ROLE_CREATE')
# PackageMetaData
- GET /api/packageMetadata => hasRole('ROLE_VIEW')
- GET /api/packageMetadata/** => hasRole('ROLE_VIEW')
# Repositories
- GET /api/repositories => hasRole('ROLE_VIEW')
- GET /api/repositories/** => hasRole('ROLE_VIEW')
# Boot Endpoints
- GET /actuator/** => hasRole('ROLE_MANAGE')The format of each line is as follows:
HTTP_METHOD URL_PATTERN '⇒' SECURITY_ATTRIBUTE
where
-
HTTP_METHOD is one http method, capital case.
-
URL_PATTERN is an Ant-style URL pattern.
-
SECURITY_ATTRIBUTE is a SpEL expression (see docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#el-access)
-
Each of those parts is separated by one or several white space characters (spaces, tabs, and others).
Be mindful that the above is indeed a YAML list, not a map (thus the use of '-' dashes at the start of each line) that lives under the spring.cloud.skipper.security.authorization.rules key.
21.1.1. Users and Roles
Spring Cloud Skipper does not make any assumptions of how roles are assigned to users.
Due to the fact that the determination of security roles is very environment-specific, Spring Cloud Data Skipper, by default, assigns all roles to authenticated OAuth2 users by using the DefaultAuthoritiesExtractor class.
You can customize that behavior by providing your own Spring bean definition that extends Spring Security OAuth’s AuthoritiesExtractor interface.
In that case, the custom bean definition takes precedence over the default one provided by Spring Cloud Skipper.
21.2. OAuth Authentication Using the Spring Cloud Skipper Shell
If your OAuth2 provider supports the Password Grant Type, you can start the Skipper shell with the following command:
$ java -jar spring-cloud-skipper-shell-2.0.0.M2.jar \
--spring.cloud.skipper.client.serverUrl=http://localhost:7577 \
--spring.cloud.skipper.client.username=my_username \
--spring.cloud.skipper.client.password=my_password| When authentication for Spring Cloud Skipper is enabled, the underlying OAuth2 provider must support the Password OAuth2 Grant Type if you want to use the hell. |
From within the Skipper shell, you can also provide credentials by using the following command:
skipper:> skipper config --uri https://localhost:7577/api --username my_username --password my_passwordOnce successfully targeted, you should see the following output:
Successfully targeted http://localhost:7577/api
skipper:>21.3. OAuth2 Authentication Examples
This section provides examples of some common security arrangements for Skipper:
21.3.1. Local OAuth2 Server
With Spring Security OAuth, you can create your own OAuth2 Server by using the following annotations:
-
@EnableResourceServer -
@EnableAuthorizationServer
You can find a working example application at https://github.com/ghillert/oauth-test-server/.
To do so, clone the project, build it, and start it. Then configure Spring Cloud Skipper with the respective Client ID and Client Secret.
| Use this option only for development or demo purposes. |
21.3.2. Authentication Using UAA
If you need to set up a production-ready OAuth provider, you may want to consider using the CloudFoundry User Account and Authentication (UAA) Server. While it is used by Cloud Foundry, it can also be used stand-alone. For more information see github.com/cloudfoundry/uaa.
21.3.3. Authentication using GitHub
If you would like to use an existing OAuth2 provider, here is an example for GitHub. First, you need to register a new application under your GitHub account at: https://github.com/settings/developers
For the Authorization callback URL, enter Spring Cloud Skippers’s Login URL — for example, localhost:9393/login.
|
Configure Spring Cloud Skipper with the GitHub Client ID and Secret, as follows:
security:
oauth2:
client:
client-id: your-github-client-id
client-secret: your-github-client-secret
access-token-uri: https://github.com/login/oauth/access_token
user-authorization-uri: https://github.com/login/oauth/authorize
resource:
user-info-uri: https://api.github.com/user| GitHub does not support the OAuth2 password grant type. As a result, you cannot use the Spring Cloud Skipper shell in conjunction with GitHub. |
Skipper Commands
Skipper commands fit into the following categories:

This command upgrades a package.
- NAME
-

--app-names string application names to force upgrade. If no specific list is provided, all the apps in the packages are force upgraded [Optional, default = <none>]
Upgrades a package, as shown (with output) in the following example:
skipper:>release upgrade --release-name helloworldlocal --package-name helloworld --package-version 1.0.0 --properties spec.applicationProperties.server.port=9090
helloworldpcf has been upgraded. Now at version v2.The manifest for this release would look like this:
"apiVersion": "skipper.spring.io/v1"
"kind": "SpringCloudDeployerApplication"
"metadata":
"name": "helloworld"
"type": "demo"
"spec":
"resource": "maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld"
"version": "1.0.0.RELEASE"
"applicationProperties":
"server.port": "9090"
"deploymentProperties": !!null "null"If no package-version is specified, the latest package version by the given --package-name option is considered.
The properties can either be provided through comma separated YAML string by using the --properties option or through a YAML
file by using the --file option.
An upgrade can be done by overriding the package version or by keeping the existing package version but overriding the properties.
When overriding the package version, it needs to accompany with the corresponding properties as the existing properties are not carried over.
In a future release, we plan to introduce a --reuse-properties command that will carry the current release properties over to the next release to be made.
|
For instance, if the package version is not changed but only other properties are changed, the manifest would add the new properties with the existing properties of the same package version.
skipper:>release upgrade --release-name helloworldlocal --package-name helloworld --package-version 1.0.0 --properties spec.applicationProperties.log.level=DEBUG
helloworldpcf has been upgraded. Now at version v3."apiVersion": "skipper.spring.io/v1"
"kind": "SpringCloudDeployerApplication"
"metadata":
"name": "helloworld"
"type": "demo"
"spec":
"resource": "maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld"
"version": "1.0.0.RELEASE"
"applicationProperties":
"server.port": "9090"
"log.level": "DEBUG"
"deploymentProperties": !!null "null"Instead, if the upgrade is performed with a new package version as follows,
skipper:>release upgrade --release-name helloworldlocal --package-name helloworld --package-version 1.0.1
helloworldpcf has been upgraded. Now at version v3.Since the package version is changed, the manifest wouldn’t carry the properties from the existing release.
skipper:>manifest get helloworldlocal
"apiVersion": "skipper.spring.io/v1"
"kind": "SpringCloudDeployerApplication"
"metadata":
"name": "helloworld"
"type": "demo"
"spec":
"resource": "maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld"
"version": "1.0.1.RELEASE"
"applicationProperties": !!null "null"
"deploymentProperties": !!null "null"When performing an update on a package that contains nested packages, use the name of the package as a prefix in the property string or as the first level in the YAML document.
For example, the ticktock package that contains a time and a log application, a command to upgrade the log application would be as follows:
skipper:>release upgrade --release-name ticktockskipper --package-name ticktock --file /home/mpollack/log-level-change.ymlwhere log-level-change.yml contains the following:
log:
version: 1.1.1.RELEASE
spec:
applicationProperties:
server.port: 9999
endpoints.sensitive: false
log.level: ERRORSince it is a common use-case to change only the version of the application, the packages can list the version as a top-level property in the values.yml file.
For example, in the test package ticktock (located here), values.yml contains the following:
version: 1.1.0.RELEASE
spec:
applicationProperties:
log.level: DEBUG
deploymentProperties:
memory: 1024mYou can then use the --properties option in the upgrade command, as shown in the following example:
skipper:>release upgrade --release-name ticktockskipper --package-name ticktock --properties log.version=1.1.1.RELEASEYou can use --timeout-expression to alter timeout setting used to wait healthy applications
when server is in state to do that. Global setting to override is
spring.cloud.skipper.server.strategies.healthcheck.timeoutInMillis mentioned earlier. More about
expression itself, see Timeout Expression.
skipper:>release upgrade --release-name ticktockskipper --package-name ticktock --timeout-expression=30sThe --force option is used to deploy new instances of currently deployed applications.
In other words, Skipper will upgrade the application again even if the manifest is unchanged.
This behavior is needed in the case when configuration information is obtained by the application itself at startup time, for example from Spring Cloud Config Server.
You can specify which applications for force upgrade by using the option --app-names.
If you do not specify any application names, all the applications will be force upgraded.
You can specify --force and --app-names options together with --properties or --file options.
Following example describes force upgrade:
First, install the package ticktock that has time and log apps.
skipper:>package upload --repo-name local --path spring-cloud-skipper-server-core/src/test/resources/repositories/binaries/test/ticktock/ticktock-1.0.0.zip
Package uploaded successfully:[ticktock:1.0.0]
skipper:>package install --package-name ticktock --release-name a1

- OPTIONS
-

-
release cancel - Request a cancellation of current release operation.
- SYNOPSYS
-
release cancel [--release-name] string
- OPTIONS
-
- --release-name string
-
the name of the release to cancel
[Mandatory]
This command can be used to attempt a cancel for a running release operation if it supports it and release is currently in state where any type of cancellation can be attempted. For example during an upgrade server will delete old applications if new applications are detected healtly. Before state is transitioned to deleting old applications, it is possible to request cancellation of whole upgrade procedure.
One other use case is that if new applications are failed and server will timeout waiting healtly applications, it’s convenient to cancel operation without waiting full timeout to happen.
Here is an example how cancellation is attempted when upgraded applications fail:
skipper:>package install --package-name testapp --package-version 1.0.0 --release-name mytestapp
Released mytestapp. Now at version v1.

-
skipper info - Show the Skipper server being used.
- SYNOPSYS
-
skipper info
Show which server version is being used, as shown (with output) in the following example:
skipper:>info
Spring Cloud Skipper Server v1.0.0.2.0.0.M228. Generic Usage
This section contains generic notes about commands.
28.1. Timeout Expression
-
A regular long representation (using milliseconds as the default unit)
-
The standard ISO-8601 format used by java.util.Duration
-
A more readable format where the value and the unit are coupled (e.g. 10s means 10 seconds)
To specify a session timeout of 30 seconds, 30, PT30S and 30s are all equivalent. A read timeout of 500ms can be specified in any of the following form: 500, PT0.5S and 500ms.
You can also use any of the supported unit. These are:
-
ns for nanoseconds
-
ms for milliseconds
-
s for seconds
-
m for minutes
-
h for hours
-
d for days
Architecture
Skipper uses a basic client-server architecture. The server exposes a REST API that is used by the interactive shell. You can browse the API using familiar HTTP client tools. The server persists Package Metadata and Release state in a relational database.
Platforms are defined by using the following property prefix: spring.cloud.skipper.server.platform.
For each of the supported platforms (cloudfoundry, 'kubernetes’ and local), you can define multiple accounts.
Each account maps onto an instance of a Spring Cloud Deployer implementation that is responsible for deploying the applications.
The Installation shows more details, but it is important to note that the Skipper server is not tied to a deploying to a single platform.
Wherever Skipper is running, it can be configured to deploy to any platform.
For example, if Skipper is deployed on Cloud Foundry, you can still register accounts for Kubernetes and deploy apps to Kubernetes from Cloud Foundry.
The release workflow is currently a hard-coded workflow managed by the Spring Cloud State Machine project. The state of the State Machine is persisted in a relational database.
REST API Guide
This section covers the Spring Cloud Skipper REST API.
29. Overview
Spring Cloud Skipper provides a REST API that lets you access all aspects of the server. The Spring Cloud Skipper shell is a first-class consumer of the API.
29.1. HTTP Verbs
Spring Cloud Skipper tries to adhere as closely as possible to standard HTTP and REST conventions in its use of HTTP verbs. The following table shows each verb and how Skipper uses it:
| Verb | Usage |
|---|---|
|
Used to retrieve a resource. |
|
Used to create a new resource. |
|
Used to update an existing resource, including partial updates.
Also used for resources that imply the concept of |
|
Used to delete an existing resource. |
29.2. HTTP Status Codes
Skipper adheres as closely as possible to standard HTTP and REST conventions in its use of HTTP status codes. The following table shows each status and its meaning in Skipper:
| Status code | Usage |
|---|---|
|
The request completed successfully. |
|
A new resource has been created successfully.
The resource’s URI is available from the response’s |
|
An update to an existing resource has been applied successfully. |
|
The request was malformed. The response body includes an error that provides further information. |
|
The requested resource does not exist. |
29.3. Headers
Every response has the following header(s):
| Name | Description |
|---|---|
|
The |
29.4. Errors
| Path | Type | Description |
|---|---|---|
|
|
The HTTP error that occurred (for example, |
|
|
A description of the cause of the error. |
|
|
The path to which the request was made. |
|
|
The HTTP status code (for example |
|
|
The time, in milliseconds, at which the error occurred. |
29.5. Hypermedia
Spring Cloud Skipper uses hypermedia.
As a result, resources include links to other resources in their responses.
More specifically, responses are in Hypertext Application from resource to resource Language (HAL) format.
Links can be found beneath the _links key.
Consumers of the API should not create URIs themselves.
Instead they should use the links in the resources to navigate.
30. Resources
30.1. Index
The index provides the entry point into Spring Cloud Skipper’s REST API.
30.1.1. Accessing the Index
You can use a GET request to access the index.
Request Structure
The following
GET /api HTTP/1.1
Host: localhost:7577Example Request
$ curl 'http://localhost:7577/api' -iExample Response
HTTP/1.1 200 OK

}
}Links
The links are the main element of the index, as they allow you to traverse the API and execute the desired functionality. The following table dsecribes the links:
| Relation | Description |
|---|---|
|
Exposes the 'package repository' repository. |
|
Exposes the deployer repository. |
|
Exposes the package metadata repository. |
|
Exposes the release repository. |
|
Entrypoint to provide ALPS metadata that defines simple descriptions of application-level semantics. |
|
Provides meta information about the server. |
|
Exposes the release resource. |
|

30.2. Server
The Server resource exposes build and version information of the server.
30.2.1. Server info
A GET request returns meta information for Spring Cloud Skipper, including the following:
-
Server name — typically
spring-cloud-skipper-server -
Version of the server — for example,

Appendix A: Building
To build the source, you need to install JDK 1.8.
The build uses the Maven wrapper so that you do not have to install a specific version of Maven.
The main build command is
$ ./mvnw clean install
To create the executables and avoid running the tests and generating JavaDocs, use the following command:
$ ./mvnw clean package -DskipTests -Dmaven.javadoc.skip=true
You can also install Maven (>=3.3.3) yourself and run the mvn command in place of ./mvnw in the examples.
If you do so, you also might need to add -P spring if your local Maven settings do not contain repository declarations for spring pre-release artifacts.
|
You might need to increase the amount of memory available to Maven by setting a MAVEN_OPTS environment variable with a value like -Xmx512m -XX:MaxPermSize=128m.
We try to cover this in the .mvn configuration, so, if you find you have to increase memory to make a build succeed, please raise a ticket to get the settings added to source control.
|
A.1. Documentation
To generate only the REST Docs documentation, use the following command:
$ ./mvnw test -pl spring-cloud-skipper-server-core -Dtest=*Documentation*
To build the only the Asciidoctor documentation, use the following command:
$ ./mvnw package -DskipTests -Pfull -pl spring-cloud-skipper-docs
A.2. Custom Server Build
This chapter contains instructions how to create a custom server build and should cause exactly same packaged uber-jar compared to one from a Skipper build itself.
It is required to follow same Spring Boot main class structure used in Skipper itself. Example of it is shown below:
package com.example.customskipperserver;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.actuate.autoconfigure.ManagementWebSecurityAutoConfiguration;
import org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration;
import org.springframework.boot.autoconfigure.session.SessionAutoConfiguration;
import org.springframework.cloud.deployer.spi.cloudfoundry.CloudFoundryDeployerAutoConfiguration;
import org.springframework.cloud.deployer.spi.kubernetes.KubernetesAutoConfiguration;
import org.springframework.cloud.deployer.spi.local.LocalDeployerAutoConfiguration;
import org.springframework.cloud.skipper.server.EnableSkipperServer;
@SpringBootApplication(exclude = {
CloudFoundryDeployerAutoConfiguration.class,
KubernetesAutoConfiguration.class,
LocalDeployerAutoConfiguration.class,
ManagementWebSecurityAutoConfiguration.class,
SecurityAutoConfiguration.class,
SessionAutoConfiguration.class
})
@EnableSkipperServer
public class CustomSkipperServerApplication {
public static void main(String[] args) {
SpringApplication.run(CustomSkipperServerApplication.class, args);
}
}Working build file for Maven would look like something shown below:

}A.3. Importing into eclipse
You can generate Eclipse project metadata by using the following command:
$ ./mvnw eclipse:eclipse
In Eclipse, the generated projects can be imported by selecting Import existing projects from the File menu.
Appendix B: Contributing
Spring Cloud is released under the non-restrictive Apache 2.0 license and follows a standard Github development process, using Github tracker for issues and merging pull requests into master. If you want to contribute even something trivial, please do not hesitate, but please do follow the guidelines spelled out in this section.
B.1. Sign the Contributor License Agreement
Before we accept a non-trivial patch or pull request, we need you to sign the contributor’s agreement. Signing the contributor’s agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions. You will get an author credit if we do. Active contributors might be asked to join the core team and be given the ability to merge pull requests.
B.2. Code Conventions and Housekeeping
None of these conventions is essential for a pull request, but they all help. They can also be added after the original pull request but before a merge.
-
Use the Spring Framework code format conventions. Follow these instructions for setting up the eclipse formatter in eclipse or IntelliJ. Note that checkstyle is enabled in the build.
-
Make sure all new
.javafiles have a simple Javadoc class comment with at least an@authortag identifying you and preferably at least a paragraph on what the class is for. -
Add the ASF license header comment to all new
.javafiles. To do so, copy from existing files in the project. -
Add yourself as an
@authorto the.javafiles that you modify substantially (more than cosmetic changes). -
Add some Javadocs and, if you change the namespace, some XSD doc elements.
-
A few unit tests would help a lot as well — someone has to do it, and your fellow developers appreciate it.
-
If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project).
-
When writing a commit message, please follow these conventions. If you are fixing an existing issue, please add
Fixes gh-XXXXat the end of the commit message (where XXXX is the issue number).
