An old java version unfortunately.
! Download oc cli
See [Installing the cli|https://docs.openshift.com/enterprise/3.0/cli_reference/get_started_cli.html#installing-the-cli]. However, now I need a RedHat account.\\
I found another location to download the command: [http://repo.openshift3roadshow.com/clients/oc-linux.tar.gz]
Extracted this one and copied to /usr/local/bin.
Syntax:
%%collapsebox
__oc command syntax__

➜ ~ oc
Developer and Administrator Client
This client exposes commands for managing your applications, as well as lower level
tools to interact with each component of your system.
To create a new application, you can use the example app source. Login to your server and then
run new-app:
$ oc login
$ oc new-app centos/ruby-22-centos7~https://github.com/openshift/ruby-hello-world.git
This will create an application based on the Docker image 'centos/ruby-22-centos7' that builds
the source code at 'github.com/openshift/ruby-hello-world.git'. A build will start automatically and
a deployment will start as soon as the build finishes.
Once your application is deployed, use the status, get, and describe commands to see more about
the created components:
$ oc status
$ oc describe deploymentconfig ruby-hello-world
$ oc get pods
You'll be able to view the deployed application on the IP and port of the service that new-app
created for you.
You can easily switch between multiple projects using 'oc project <projectname>'.
Basic Commands:

login Log in to a server
