Installing on CoreOS
When you install the Centrify agent for *NIX on a CoreOS computer, that computer is the computer identity that you manage in Active Directory, regardless of how many containers you later create (whether or not you install the agent in those containers).
Because the nature of containers is that they may go away or be rebuilt at any time, you might find it simpler to install the agent only in the CoreOS system and not also in containers. It’s your preference as to how you want to deploy the Centrify agent inside of your CoreOS systems.
If desired, you can also install the agent only into the container; that way, the container is the identity that you manage in Active Directory.
