- vars/ocp_params
Literally, ocp_params has ocp related variable like normal ocp hosts file but only 3 params are inherited from vars/all.
- openshift_master_default_subdomain
- openshift_master_cluster_hostname
- openshift_master_cluster_public_hostname
The main variables are specified in vars/all.
