What is it?
Diun checks container image registries for new tags or digest changes and notifies you when an image has been updated. It helps track base image updates, application releases, and security rebuilds without manually checking each repository.
It is aimed at self-hosted and automated environments where outdated images can go unnoticed. Diun can run as a standalone executable or as a Docker image, and it connects to container platforms and configuration files to determine which images to watch.
Notifications can be delivered through services such as Slack, Telegram, Discord, Gotify, Pushover, and Rocket.Chat, so updates arrive in the tools you already use.
