Log in to OpenShift. See Basic Setup and Login.

$ oc login

Run the following command to verify that the version of the oc OpenShift CLI management tool is 3.11:

$ oc version
oc v3.11.0+0cbc58b

Run the following commands to create a dummy project to find the URL that this OpenShift instance is using to deploy applications.

$ oc new-project hello-world
$ oc new-app centos/httpd-24-centos7~https://github.com/openshift/httpd-ex
$ oc expose svc/httpd-ex
$ oc get route httpd-ex
NAME     HOST/PORT                                                PATH     SERVICES PORT     TERMINATION WILDCARD
httpd-ex httpd-ex-hello-world.apps.rhpds311.openshift.opentlc.com httpd-ex          8080-tcp             None

Extract the domain from httpd-ex-hello-world.apps.rhpds311.openshift.opentlc.com. It is the part after the first name: apps.rhpds311.openshift.opentlc.com. Remember this URL as <OPENSHIFT_APPS_URL>.

Remove the dummy project:

$ oc delete project hello-world
