What’s Up Docker (WUD), the self-hosted automation tool that keeps Docker containers updated, has released version 8.2 with expanded registry support and several functional improvements.
This release introduces compatibility with two additional registries: TrueForge Container Registry and Codeberg. Users can now monitor and update containers sourced from these platforms alongside existing registries.
One of the notable changes in WUD 8.2 is that digest watching — which tracks image updates using SHA256 digests instead of tags — is now enabled by default for all registries except Docker Hub. Tag candidate handling has also been refined to ensure:
- The same number of semantic version components is preserved
- The original tag prefix remains intact
- Signature tags are ignored when appropriate
For Docker Compose environments, a new wud.compose.file supported label has been added, and a bug impacting YAML files with multiple aliases has been resolved.
The update also enhances notifications and integrations, including:
- A new Rocket.Chat trigger
- SMTP improvements allowing a display name in the “from” address
- An option to disable Prometheus metrics
Under the hood, WUD’s interface has been modernized with Vue 3, Vuetify 3, and TypeScript. The backend now runs on Node.js 24, and the official Docker image has been rebuilt on Alpine for a leaner footprint.
For full details, consult the project’s changelog. And if you’re new to WUD, a step-by-step setup guide is available to help you get started quickly.
