I recently got into audio books and became an Audible subscriber. One of the first books I got stuck into was The Phoenix Project by Gene Kim, Kevin Behr, George Spafford.

You should check it out for sure.

A replication controller helps you manage your containers by allowing you to kill and bring to life new and existing containers.
Horizontally scaled. If a container temporarily dies the replication controller kicks into action a replacement container automatically.
Is tag that is used for managing your pods by naming them with key value pairs. Its for keeping organised, mostly meta data in file.
