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
alias docker_update="docker compose pull && docker compose down && docker compose up -d && docker system prune -f"
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.
