Let's list out our current available projects (those that we have at least view access for):
$ oc get projects
If this is our rst login and no one has added us to any existing projects, there shouldn't be any projects listed. Let's create a project (allowed by self-provisioner role to all authenticated users, in the default Openshift policy installation).
$ oc new-project myproject --display-name='My Project' --description='cool project owned by myuser'
Now using project "myproject" on server "https://openshift.example.com:443". To build a new example applicatin on Ruby you can add applications to this project with the 'new-app' command. For example, try:
oc new-app centos/ruby-22-centos7~https://github.com/openshift/ruby-ex.git
