# The following steps are executed to provision OpenShift Origin:
# 1. Create a private network and set the Vagrant Box IP to *10.1.2.2*. If you want a different IP then change the **PUBLIC_ADDRESS** variable.
# 2. Pull latest the *openshift/origin* container from docker hub and tag it.
# 3. Provide required configuration details for OpenShift web console and API.
# For More info about Openshift, please refer to `offical documents
