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,

docker-compose.yml

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
