Diun (Docker Image Update Notifier) is a Go tool that watches container images on Docker registries and notifies you when a tracked tag or digest changes. It runs as a single binary or Docker container, discovers images from Docker, Containerd, Kubernetes, Swarm, Nomad, Dockerfile, or file providers, and sends alerts via Slack, Telegram, Gotify, email, and many other channels.
Use cases
- get notified when a docker image is updated
- track container image tag changes on a registry
- monitor base image updates for self-hosted services
- watch kubernetes or swarm images for new digests
- schedule automatic registry checks without cron
- send image update alerts to slack or telegram
When to choose
- you self-host containers and need to know when upstream images change
- you want scheduled registry checks with multi-platform notification support
- you need image update tracking across Docker, Kubernetes, Swarm, Nomad, or Containerd
When to avoid
- you want a tool that automatically pulls and applies image updates rather than just notifying (use Watchtower)
- you need vulnerability scanning of images rather than update detection
- you don't run any container workloads
