# ntfy server config file # Public facing base URL of the service (e.g. https://ntfy.sh or https://ntfy.example.com) # This setting is currently only used by the attachments and e-mail sending feature (outgoing mail only). # # base-url: # Listen address for the HTTP & HTTPS web server. If "listen-https" is set, you must also # set "key-file" and "cert-file". Format: []:, e.g. "1.2.3.4:8080". # # To listen on all interfaces, you may omit the IP address, e.g. ":443". # To disable HTTP, set "listen-http" to "-". # # listen-http: ":80" # listen-https: # Listen on a Unix socket, e.g. /var/lib/ntfy/ntfy.sock # This can be useful to avoid port issues on local systems, and to simplify permissions. # # listen-unix: # Path to the private key & cert file for the HTTPS web server. Not used if "listen-https" is not set. # # key-file: # cert-file: # If set, also publish messages to a Firebase Cloud Messaging (FCM) topic for your app. # This is optional and only required to save battery when using the Android app. # # firebase-key-file: # If set, messages are cached in a local SQLite database instead of only in-memory. This # allows for service restarts without losing messages in support of the since= parameter. # # The "cache-duration" parameter defines the duration for which messages will be buffered # before they are deleted. This is required to support the "since=..." and "poll=1" parameter. # To disable the cache entirely (on-disk/in-memory), set "cache-duration" to 0. # The cache file is created automatically, provided that the correct permissions are set. # # Debian/RPM package users: # Use /var/cache/ntfy/cache.db as cache file to avoid permission issues. The package # creates this folder for you. # # Check your permissions: # If you are running ntfy with systemd, make sure this cache file is owned by the # ntfy user and group by running: chown ntfy.ntfy . # # cache-file: # cache-duration: "12h" # If set, access to the ntfy server and API can be controlled on a granular level using # the 'ntfy user' and 'ntfy access' commands. See the --help pages for details, or check the docs. # # - auth-file is the SQLite user/access database; it is created automatically if it doesn't already exist # - auth-default-access defines the default/fallback access if no access control entry is found; it can be # set to "read-write" (default), "read-only", "write-only" or "deny-all". # # Debian/RPM package users: # Use /var/lib/ntfy/user.db as user database to avoid permission issues.
