Docker - diun & ntfy
ntfy is a notification application and server frame work. It has an iOS client and can also use standard web page and Andiod app. I originally considered gotify however there is not iOS application for this notification system, which basically makes it of less value for me.
A notification application sends simple messages that can be used to notify users. The interface also issues messages on the OS to warn uses that a message has come in. The user can then elect to look at the message detail. The message can be as terse or verbose as necessary, although overly verbose message may have formatting issues.
diun is used to check for Docker image updates. It then uses a notification app or email to inform that such update is available. diun basically needs a notification app to function effectively.
ntfy
nfty was leaving a whole pile of zombie processes, ssl_client
. To fix it added the init option to the docker-compose.yml configuration,
services: ntfy: image: binwiederhier/ntfy init: true container_name: ntfy command: serve environment: TZ: "Australia/Perth" # optional: set desired timezone, was UTC # Use configuration file: config/etc/ntfy/server.yml # NTFY_BASE_URL: https://ntfy.kpts.net # NTFY_CACHE_FILE: /var/lib/ntfy/cache.db # NTFY_AUTH_FILE: /var/lib/ntfy/auth.db # NTFY_AUTH_DEFAULT_ACCESS: deny-all # NTFY_BEHIND_PROXY: false # NTFY_ATTACHMENT_CACHE_DIR: /var/lib/ntfy/attachments user: 1000:1000 # optional: replace with your own user/group or uid/gid, was UID:GID volumes: - ./config/var/cache/ntfy:/var/cache/ntfy - ./config/etc/ntfy:/etc/ntfy ports: - 8083:80 healthcheck: # optional: remember to adapt the host:port to your environment test: ["CMD-SHELL", "wget -q --tries=1 https://ntfy.kptree.net/v1/health -O - | grep -Eo '\"healthy\"\\s*:\\s*true' || exit 1"] interval: 60s timeout: 10s retries: 3 start_period: 40s restart: unless-stopped
ntfy configuration is stored /etc/ntfy/server.yml
.
# 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: https://ntfy.kptree.net # Listen address for the HTTP & HTTPS web server. If "listen-https" is set, you must also # set "key-file" and "cert-file". Format: [<ip>]:<port>, 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: <socket-path> # listen-unix-mode: <linux permissions, e.g. 0700> # Path to the private key & cert file for the HTTPS web server. Not used if "listen-https" is not set. # # key-file: <filename> # cert-file: <filename> # 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: <filename> # 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 <filename>. # cache-file: /var/cache/ntfy/cache.db cache-duration: "24h" # 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 <filename>. # # auth-file: <filename> # 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.

Note that setting the rate visitor # requires **read-write permission** on the topic. # # If this setting is enabled, publishing to UnifiedPush topics will lead to a HTTP 507 response if # no "rate visitor" has been previously registered.

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 <filename>. # # 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: /var/log/ntfy.log
