I just released the new major release 2.0 of Diun and I think this one might interest you.

For those who don't know, Diun 🔔 is a CLI application written in Go to receive notifications 📥 when a Docker 🐳 image is updated on a Docker registry.

Mail notification

In its first version this one only allowed the analysis of images added manually in the configuration file.

But in this new release, there is the addition of support for Docker engines provider and Swarm clusters provider. I put it in the plural because you can add as many engines as you want. This may allow some sysadmin to centralize notifications when analyzing images.

For these new providers, the analysis can be done on all the containers/services found (even those stopped). The configuration can be global for your provider or more refined by the introduction of Docker labels dedicated to Diun:

version: "3.5"

services:
  diun:
    image: crazymax/diun:latest
    volumes:
      - "./data:/data"
      - "./diun.yml:/diun.yml:ro"
      - "/var/run/docker.sock:/var/run/docker.sock"
    environment:
      - "TZ=Europe/Paris"
      - "LOG_LEVEL=info"
      - "LOG_JSON=false"
    restart: always

  cloudflared:
    image: crazymax/cloudflared:latest
    ports:
      - target: 5053
        published: 5053
        protocol: udp
      - target: 49312
        published: 49312
        protocol: tcp
    environment:
      - "TZ=Europe/Paris"
      - "TUNNEL_DNS_UPSTREAM=https://1.1.1.1/dns-query,https://1.0.0.1/dns-query"
    labels:
      - "diun.enable=true"
      - "diun.watch_repo=true"
    restart: always

Logs will look like:

$ docker-compose logs -f
