# Local overrides — copy to docker-compose.override.yaml in the repo root.
# Compose automatically merges this with docker-compose.yaml.

# Volumes are APPENDED to the base file's volumes list.
# Environment and other scalar keys are MERGED by key.

volumes:
## Data paths — bind-mount to host directories for easy access/backup.
# - ./data/dkim:/etc/dkimkeys
# - ./data/certs:/var/lib/acme
# - ./data/mail:/home/vmail
## Or mount from an existing bare-metal install.
# - /home/vmail:/home/vmail
## Mount your own chatmail.ini (skips auto-generation):
# - ./chatmail.ini:/etc/chatmail/chatmail.ini
## Custom website:
# - ./custom/www:/opt/chatmail-www
## Debug — mount scripts from the repo for live editing:
# - ./docker/files/setup_chatmail_docker.sh:/setup_chatmail_docker.sh
# - ./docker/files/entrypoint.sh:/entrypoint.sh
# environment:
## Mount certs (above) and set TLS_EXTERNAL_CERT_AND_KEY to in-container paths.
## Changed certs are picked up automatically (inotify via tls-cert-reload.path).
##
## Host acmetool (bare-metal migration): create mount above, and
## rsync -a /var/lib/acme/live data/certs
# TLS_EXTERNAL_CERT_AND_KEY: "/var/lib/acme/live/${MAIL_DOMAIN}/fullchain /var/lib/acme/live/${MAIL_DOMAIN}/privkey"
##
## (Untested) Traefik certs-dumper (see docker/docker-compose-traefik.yaml) - also add volume:
## - traefik-certs:/certs:ro
# TLS_EXTERNAL_CERT_AND_KEY: "/certs/${MAIL_DOMAIN}/certificate.crt /certs/${MAIL_DOMAIN}/privatekey.key"
