Your Docker containers, always up to date
A Docker container update monitor powered by WUD (What's Up Docker), installed and maintained by DINAO. Get notified as soon as a new image is available — supervision hosted in France.
What is WUD?
WUD (What's Up Docker) is an open source and self-hostable tool that simplifies container maintenance by monitoring image updates. It observes containers running on your Docker hosts, checks for newer versions, and alerts you as soon as a new image is published — a welcome alternative to Watchtower, which is now discontinued.
Its architecture is based on three components: Watchers, which scan Docker hosts to discover containers to monitor; Registries, which query remote registries (Docker Hub, GitHub Container Registry, GitLab…) to find candidate versions; and Triggers, which execute actions when an update is available.
WUD offers a notification-only mode, to keep full control over when to update, or a fully automated mode that stops the container, downloads the updated image, and restarts it. Triggers cover emails, webhooks, scripts, and numerous messaging services (Telegram, Discord, Slack, Pushover).

What is WUD (What's Up Docker)?
WUD is an open source tool that monitors your Docker containers and continuously checks if new versions of their images are available, then alerts you — an alternative to Watchtower, which is now discontinued.
Does WUD automatically update my containers?
Your choice. In notification-only mode, WUD notifies you and you keep control over when to update. In automated mode, it stops the container, downloads the new image, and restarts it on its own.
Which registries are supported?
WUD queries Docker Hub, GitHub Container Registry, GitLab, and other registries, including private ones depending on the plan, to find candidate versions.
How am I alerted?
Via various triggers: email, webhook, scripts, as well as Telegram, Discord, Slack, or Pushover.
Where is the data stored?
On your DINAO instance in France. Your container inventory and triggers remain hosted on French territory.
