Overview

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).

Host WUD at DINAO

No managed container for WUD: this application is installed on a VPS hosted in France (1 vCPU / 256 Mo / 1 Go minimum).

WUD needs a level of access to the machine that the managed container, shared between several customers, does not give. Two VPS hosted in France: DINAO installs and manages it for you, or you administer it yourself.

Technical reason: mounting the Docker socket (full control of the host).

Option 2 The simplest

Managed VPS with Docker and the application pre-installed

from €28,70 /month excl. VAT

  • WUD installed by DINAO when you order
  • The machine is yours alone: WUD can control Docker on it without affecting any other customer
  • System and Docker managed by DINAO, monitoring included
  • Priority support included (2-hour response time, DINAO business days and hours)
  • Stated, capped resources (2 vCPU, 2 GB, 20 GB): beyond that, a larger size is offered

Frequently asked questions

You might be wondering…

About WUD 6 questions

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.

Is this application tested before it is offered?

This application has not yet passed our automatic deployment test. It can still be installed, but we invite you to contact us before ordering: we will then test it as a priority. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.
