⚠️ ATTENTION: Nginx configuration mount ${CONF_ACTIVE_DIR} is missing.
|
|
|
|
Custom listen address or port changes require a writable nginx conf.active
|
|
directory. Without it, the container falls back to defaults and ignores
|
|
your overrides.
|
|
|
|
Create a bind mount:
|
|
--mount type=bind,src=/path/on/host,dst=${CONF_ACTIVE_DIR}
|
|
and ensure it is owned by the netalertx user (20211:20211) with 700 perms.

Ensure the conf.active mount is writable by the netalertx user before
|
|
changing LISTEN_ADDR or PORT. Fix permissions:
|
|
chown -R 20211:20211 ${CONF_ACTIVE_DIR}
|
|
find ${CONF_ACTIVE_DIR} -type d -exec chmod 700 {} +
|
|
find ${CONF_ACTIVE_DIR} -type f -exec chmod 600 {} +
