# ntfy server config file # # Please refer to the documentation at https://ntfy.sh/docs/config/ for details. # All options also support underscores (_) instead of dashes (-) to comply with the YAML spec. # Public facing base URL of the service (e.g. https://ntfy.sh or https://ntfy.example.com) # # This setting is required for any of the following features: # - attachments (to return a download URL) # - e-mail sending (for the topic URL in the email footer) # - iOS push notifications for self-hosted servers (to calculate the Firebase poll_request topic) # - Matrix Push Gateway (to validate that the pushkey is correct) # # 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: # listen-unix-mode: # 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 "cache-file" is 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. # # The "cache-startup-queries" parameter allows you to run commands when the database is initialized, # e.g. to enable WAL mode (see https://phiresky.github.io/blog/2020/sqlite-performance-tuning/)). # Example: # cache-startup-queries: | # pragma journal_mode = WAL; # pragma synchronous = normal; # pragma temp_store = memory; # pragma busy_timeout = 15000; # vacuum; # # The "cache-batch-size" and "cache-batch-timeout" parameter allow enabling async batch writing # of messages. If set, messages will be queued and written to the database in batches of the given # size, or after the given timeout. This is only required for high volume servers. # # 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" # cache-startup-queries: # cache-batch-size: 0 # cache-batch-timeout: "0ms" # 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". # - auth-startup-queries allows you to run commands when the database is initialized, e.g. to enable # WAL mode. This is similar to cache-startup-queries. See above for details. # # Debian/RPM package users: # Use /var/lib/ntfy/user.db as user database to avoid permission issues. The package # creates this folder for you. # # Check your permissions: # If you are running ntfy with systemd, make sure this user database file is owned by the # ntfy user and group by running: chown ntfy.ntfy . # # auth-file: # auth-default-access: "read-write" # auth-startup-queries: # If set, the X-Forwarded-For header is used to determine the visitor IP address # instead of the remote address of the connection. # # WARNING: If you are behind a proxy, you must set this, otherwise all visitors are rate limited # as if they are one. # # behind-proxy: false # If enabled, clients can attach files to notifications as attachments.

Some options (log-level and log-level-overrides) can be hot reloaded # by calling "kill -HUP $pid" or "systemctl reload ntfy". # # - log-format defines the output format, can be "text" (default) or "json" # - log-file is a filename to write logs to. If this is not set, ntfy logs to stderr. # - log-level defines the default log level, can be one of "trace", "debug", "info" (default), "warn" or "error". # Be aware that "debug" (and particularly "trace") can be VERY CHATTY. Only turn them on briefly for debugging purposes. # - log-level-overrides lets you override the log level if certain fields match. This is incredibly powerful # for debugging certain parts of the system (e.g. only the account management, or only a certain visitor). # This is an array of strings in the format: # - "field=value -> level" to match a value exactly, e.g. "tag=manager -> trace" # - "field -> level" to match any value, e.g. "time_taken_ms -> debug" # Warning: Using log-level-overrides has a performance penalty. Only use it for temporary debugging. # # Check your permissions: # If you are running ntfy with systemd, make sure this log file is owned by the # ntfy user and group by running: chown ntfy.ntfy . # # Example (good for production): # log-level: info # log-format: json # log-file: /var/log/ntfy.log # # Example level overrides (for debugging, only use temporarily): # log-level-overrides: # - "tag=manager -> trace" # - "visitor_ip=1.2.3.4 -> debug" # - "time_taken_ms -> debug" # # log-level: info # log-level-overrides: # log-format: text # log-file:
