I see someone mention watchtower, while not a bad thing, I just prefer to manually update. This helps to ensure any breaking changes don’t break my system. Especially with something like Immich at it’s had a lot of them recently as they work towards stable. I just generally subscribe to their release and do updates as necessary.

Now that you mention it, I always do a

docker system prune -f

This will clean up old images that are no longer used. I setup an alias command in Linux to do all of those commands.

I just named it docker_update and saved it in my ~/.bashrc

Did you use docker compose file or just run a command to start the container?

Edit: I always use compose files. For that you can do the following:

docker compose pull
docker compose down
docker compose up -d

You don’t technically need the stop, but I’ve found once or twice in the past where it was good to stop because of image dependencies that I forgot to put in my compose.

For running a command directly I found this website that seems to summarize it pretty well I think:

I wonder if making a blueprint for the floors would be easy enough. Might make the whole thing a lot quicker.
