It probably depends on the place, I know projects that use Ansible, I know some that use Docker Swarm, I know some that also are either all in on Kubernetes or, quite the opposite, run in a VM or on bare metal somewhere.

Honestly, sometimes Ansible or even Docker Swarm or something like Docker Compose are nice to use because they’re a better fit for a problem than one of the “mainstream” solutions (e.g. Kubernetes is great but has complexity to manage, unless you can pay someone else to provide a cluster for you).

Sadly, none of that matters when you’re looking for a job and the latest mainstream technologies reign supreme then.
