# Piege : PGDATA de l'image timescaledb-ha vaut /home/postgres/pgdata/data, pas le chemin
# habituel de l'image postgres. Monte ailleurs, le volume ne retient rien, sans erreur.
# Piege : db/init est monte fichier par fichier. Monter le dossier masquerait les scripts
# d'init de l'image, dont timescaledb-tune. Ajouter un fichier impose une ligne ici.

# Piege : LocalExecutor fait tourner les taches comme sous-processus du scheduler, jamais du
# webserver. `airflow_ml_state` (modele entraine, magasin MLflow) n'a donc besoin d'etre monte
# que sur `airflow-scheduler` en pratique, mais reste partage avec le webserver pour que ce
# dernier puisse au besoin l'inspecter sans en devenir dependant.
