If I read this correctly, Immich is setup entirely through Ansible, no docker compose. That’s fine, however if Immich changes something drastically in their setup topology, it’ll be more work for you to implement those changes. For services that use docker compose, you could use Ansible to deploy a compose file in a dir, say /opt/immich-docker along with its requisite .env and other files. Then setup running it via systemd. Then when you need to update it, it’s almost copy-paste from the upstream compose file into your Ansible repo.
