How to enable OpenShift oc bash auto completion

If you deployed the Openshift Linux client from tar.gz, bash auto completion script will not be enabled by default. You have to enable it manually with the following commands

# yum -y install bash-completion
# oc completion bash >>/etc/bash_completion.d/oc_completion

Logout and login again to activate oc completion. Type oc then press TAB two times. You will see all available options.
