By default, Skipper will deploy apps to the local machine. The default configuration also has one local repository named local where you can upload packages, and one remote repository named experimental where some sample test packages are located. You get get a list of the package repositories by using the command repo list

	Note
	The shell supports tab completion.

skipper:>repo list

Install the Maven based Hello World application using the install command. Since this application picks a random port for the http server by default, we specify the Spring Boot property server.port, prefixed via spec.applicationProperties.

skipper:>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.

$ curl http://localhost:8099/greeting
Hello World!

The release name helloworld-local is used for subsequent commands such as status, upgrade or delete.

To see the status of the release, use the status command

skipper:>status --release-name helloworld-local

Let’s 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 Portugese`.

skipper:>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.

This will deploy the new version of the application, wait until it is healthy, and then destroy the old version of the application.

skipper:>status --release-name helloworld-local

You can now curl the greeting endpoint at the new port and see that the application has been updated.

$ curl http://localhost:8100/greeting
Olá Mundo!

To delete the release, use the delete command.

skipper:>delete --release-name helloworld-local
helloworld-local has been deleted.

	Note
	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 in the updated application so that it behaves differently.

You can also deploy the other packages named helloworld-docker to the local machine.

This example shows the most basic operations, other interesting commands such as manifest get, rollback, list and history are covered in the Part IV, “Three minute Tour”.
