My last post on Linux security hardening briefly mentioned Ansible Tower. Ansible itself is very good at configuration management. It is lightweight, agentless and easy to get started with. But once you manage more than a few configuration items, more than a few target systems and work together with other administrators, Ansible as a command line tool doesn’t scale well.
Similar to how Red Hat Satellite replaced yum update in larger environments, Ansible Tower makes Ansible scalable and gives it a Web UI and REST API. The Ansible Tower Web site has a nice 2-minute overview, and below, I’ll walk you through installing and using Ansible Tower 3.
