Skipper is a tool that allows you to 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 achieve Continuous Deployment of applications. For more details, review the reference guide for a complete overview and the feature capabilities.
Before we begin setting up Skipper to use with Spring Cloud Data Flow, let’s review the basics by understanding foundational design by which the relevant infrastructure is provisioned in Kubernetes. The tailormade three-minute-tour for Cloud Foundry walks through the fundamentals.
Next up, we will review the relevant artifacts to provision Spring Cloud Skipper in Cloud Foundry.
wget http://repo.spring.io/snapshot/org/springframework/cloud/spring-cloud-skipper-server/1.0.0.BUILD-SNAPSHOT/spring-cloud-skipper-server-1.0.0.BUILD-SNAPSHOT.jar wget http://repo.spring.io/snapshot/org/springframework/cloud/spring-cloud-skipper-shell/1.0.0.BUILD-SNAPSHOT/spring-cloud-skipper-shell-1.0.0.BUILD-SNAPSHOT.jar
Similar to SCDF-server, you can either deploy the skipper-server application on Cloud Foundry or on your local machine.
Let’s review the sample manifest.yml
file to deploy the skipper-server application to Cloud Foundry.
--- applications: - name: skipper-server host: skipper-server memory: 1G disk_quota: 1G instances: 1 path: <PATH TO THE DOWNLOADED SKIPPER SERVER UBER-JAR> env: SPRING_APPLICATION_NAME: skipper-server 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: {org} SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_SPACE: {space} SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_DOMAIN: cfapps.io SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_USERNAME: {email} SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_PASSWORD: {password} SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_DEPLOYMENT_SERVICES: rabbit SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_CLOUDFOUNDRY_ACCOUNTS[pws]_CONNECTION_STREAM_ENABLE_RANDOM_APP_NAME_PREFIX: false
You need to fill in {org}, {space}, {email} and {password} before running these commands. Once you have the desired
config values in the manifest.yml
, you can run cf push
command to provision the skipper-server.

Skipper includes the concept of platforms,
so it is important to define the "accounts" based on the project preferences. In the above YAML file, the accounts map
