You don't have any projects. You can try to create a new project, by running

oc new-project <projectname>


C:\Users\jkriker\Desktop>oc new-project jlk-from-oc-cli
Now using project "jlk-from-oc-cli" on server "https://api.starter-us-west-2.openshift.com:443".

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

to build a new example application in Ruby.

C:\Users\jkriker\Desktop>oc new-app centos/ruby-22-centos7~https://github.com/openshift/ruby-ex.git
--> Found Docker image 83e3e70 (36 hours old) from Docker Hub for "centos/ruby-22-centos7"

* An image stream will be created as "ruby-22-centos7:latest" that will track the source image
* A source build using source code from https://github.com/openshift/ruby-ex.git will be created
* The resulting image will be pushed to image stream "ruby-ex:latest"
* Every time "ruby-22-centos7:latest" changes a new build will be triggered
* This image will be deployed in deployment config "ruby-ex"
* Port 8080/tcp will be load balanced by service "ruby-ex"
* Other containers can access this service through the hostname "ruby-ex"
