Should I move to Docker? (lemmy.ca)

I'm a retired Unix admin. It was my job from the early '90s until the mid '10s. I've kept somewhat current ever since by running various machines at home. So far I've managed to avoid using Docker at home even though I have a decent understanding of how it works - I stopped being a sysadmin in the mid '10s, I still worked for a technology company and did plenty of "interesting" reading and training.

It seems that more and more stuff that I want to run at home is being delivered as Docker-first and I have to really go out of my way to find a non-Docker install.

I'm thinking it's no longer a fad and I should invest some time getting comfortable with it?

If you decide to use docker-compose.yml files, which I do recommend, then I'd also highly recommend this script for updating the docker containers.

It checks each container for updates and then let's you select the containers you would like to update. I just keep it in the main directory with all the other docker container directories.

The preferred filename is now compose.yaml, see https://docs.docker.com/compose/compose-file/03-compose-file/

Compose also supports docker-compose.yaml and docker-compose.yml for backwards compatibility of earlier versions.

I doubt they’re going to remove support for the previous filename anytime soon. It would break way too many things.

Why not just run a watchtower container? Combined with a diun one to send gotify messages to my phone if you're into that. (I am!)

Sometimes automated updates are not desirable. I also prefer the simplicity of a bash script over a full container.
