# Playbook: deploy-immich.yml
#
# But:
# - Deployer Immich dans le LXC immich
# - Copier le docker-compose.yml depuis Git
# - Verifier que le fichier .env.runtime existe deja sur le LXC
# - Creer les dossiers runtime locaux
# - Demarrer la stack Docker Compose
# - Verifier que le port 2283 repond
#
# Important:
# - Le fichier .env.runtime ne doit pas etre dans Git
# - Le fichier .env.runtime doit etre sur le LXC:
#   /opt/stacks/immich/.env.runtime
# - Ce playbook ne touche pas encore aux bibliotheques NAS
