I have a docker compose file I keep in a github repo. It has every app I need in it. I can grab any server off the shelf slam an OS on it, mount my nfs share, git clone, docker compose up and I am done. I am in the boat where I keep everything in a compose file instead of multiple files.It works for me, I love it.
*EDIT*I used to use watchtower but broke a big chunk of my stuff with auto updates. I stay away from them now. I plan them
