Continuing the topic of handling deployments on day #21.
Previously we had a look at deploying new version of application: OpenShift Morsels: rolling out new version of application. Today the continuation of oc rollout subcommands.
Displaying history refers to the previous deployments through Replication Controllers. They are the history of your deployments. After deleting the Replication Controller number 1, it is no longer visible in history and you can’t deploy it anymore. You can see the output of all 3 commands below.

As for the other subcommands, status displays information about latest deploy state. It waits for updates from all started replicas and afterwards reports just final status.
