What is CoreOS?

It is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, it uses Linux containers to manage your services at a higher level of abstraction. A single service's code and all dependencies are packaged within a container that can be run on one or many machines.

We only use Ansible for some limited cluster-management, irregular maintenance tasks and low-level docker debugging and re-configuration on the individual servers, as we chose CoreOS (Fedora CoreOS) as our operating system and setup is done with an ignition-configuration.
