#
# Deux reseaux :
#   - "default" : prive, Kafka et PostgreSQL n'y sont joignables que par l'app.
#     Aucun port n'est publie sur l'hote - le broker n'est pas expose a Internet.
#   - "edge"    : reseau externe partage, ou le reverse proxy Caddy du serveur
#     vient chercher l'application pour la servir en HTTPS.
#
# Note sur Zookeeper : absent volontairement. Kafka tourne en mode KRaft, son
# quorum interne. Zookeeper est deprecie depuis Kafka 3.5 et supprime en 4.0 ;
# le garder ajouterait un conteneur, ~400 Mo de RAM et une piece a maintenir.
