How Do Install and Configure OpenShift to Test It Out?

Problem scenario
You want to use OpenShift as opposed to Kubernetes.  How do you deploy OpenShift to try it out?

1.  Install Docker on Linux.  We recommend you use a RedHat OS.  The hardware requirements are not that high if you are just testing it for development and/or learning purposes.  For directions on how to install Docker on a RedHat distribution of Linux, see this posting if it is in AWS.  For directions on installing Docker on a RHEL VM in GCP, see this posting.

2.  Run these three commands:

sudo service docker start

docker run -d --name "origin2" --privileged --pid=host --net=host -v /:/rootfs:ro -v /var/run:/var/run:rw -v /sys:/sys -v /sys/fs/cgroup:/sys/fs/cgroup:rw -v /var/lib/docker:/var/lib/docker:rw -v /var/lib/origin/openshift.local.volumes:/var/lib/origin/openshift.local.volumes:rslave openshift/origin start

docker exec -it origin2 bash

3.  Now that you are inside the Docker container, run this command:

oc login # for the username and password use "test" and "test" respectively

4.  Now you can run oc commands to test openshift.  Try these:

oc version
oc whoami

(The above commands were mostly taken from The old link was, but this no longer works.)

FYI  The "oc" command (which stands for OpenShift Client) is very similar to the way that kubectl works.
