1. Install Podman and passt + slirp4netns for networking
2. Setup subuid and subgid usermod --add-subuids 100000-165535 --add-subgids 100000-165535 johndoe
3. I'm using quadlet's so we need to create those: $HOME/.config/containers/systemd/immich-database.container

Network=immich.network # attach to the podman network
UserNS=keep-id:uid=999,gid=999 # This makes uid 999 and gid 999 map to the user running the service, this is so that you can access the files in the volume without any special handling otherwise root would map to your uid and the uid 999 would map to some very high uid that you can't access without podman - This modifies the image at runtime and may make the systemd service timeout, maybe increase the timeout on low-powered machines

WantedBy=multi-user.target default.target

4. systemctl --user daemon-reload
5. systemctl --user enable --now immich-server.service
6. enable linger so systemd user services run even if the user is logged of loginctl enable-linger $USER
7. Setup a reverse proxy like caddy so you can make access to it simple like immich.mini-pc.localnet
