Overview

WUD is an open source container update monitor. It reads the container runtime on a host, works out which image and tag every container is running, then asks the image's registry whether a newer version exists, and reports the answer on a web dashboard and a REST API. Registry support covers the public hub, GitHub and GitLab registries, Quay, Amazon ECR, Azure Container Registry, Gitea and Forgejo, and self hosted registries.

When an update appears it fires the integrations you configure, so the news reaches you rather than waiting to be noticed: email, chat, webhooks, MQTT and more. Per container labels let you decide which tags count as an upgrade, so a container pinned to a stable line is never told about a pre release.

Why the cloudimg image

The cloudimg image is self proving: it boots with a real workload already running on a deliberately out of date tag and a matching local registry, so the dashboard shows a genuine update available at first sign in instead of an empty screen, with no registry credentials and no outbound network needed. Nothing binds a public port until first boot has minted a unique administrator credential for that VM, the monitor refuses to start if that credential is missing, and the container socket stays local to the host. It ships fully patched on Ubuntu 24.04 with a paired deployment guide and 24/7 support.
