Same, but I haven't started with anything like Ansible yet, only beginning to learn it at work.

Running all my services in Docker keeps it all clean because I'm a very messy person when it comes to Linux. Change, change, change, it works, forget about it, it breaks, find something I did years ago tripping me up now, change, change, change, it works, forget about it.

With docker every service is contained and nearly separated. I can rip something out and replace it like stacking a new network switch in the rack. Delete the container, delete the image(s) and delete the volume if I want to start over with something completely fresh.

I can move everything to a new server by moving bulk hard drives over, restoring docker volumes from backup and cloning docker-compose configs from git. Haven't tried any distributed volume storage yet.
