WatchDigest

Monitoring tool that scans Docker containers for outdated images and can auto-update them

Servicefreeglobal

WatchDigest is a lightweight, Python-based tool that scans local Docker containers for outdated image digests and can optionally update them, notifying users across messaging platforms like Discord, Telegram, Matrix, and Gotify. Inspired by Watchtower, it's aimed at self-hosted Docker operators who want visibility into which running containers are behind on updates.
