What’s Up Docker 8.2 Enables Digest Watching by Default

Docker Automation Just Got Smarter: WUD 8.2 Unleashes New Registry Support, Enhanced Tagging, and a Modernized UI

The self-hosted container automation world just leveled up. What’s Up Docker (WUD), the go-to tool for keeping Docker containers fresh and up to date, has rolled out version 8.2—and it’s packing more than just bug fixes. This release brings expanded registry support, smarter tag handling, enhanced integrations, and a sleek modern UI overhaul that’ll make even the most seasoned DevOps engineer smile.

Two New Registries Join the Party

If you’re working with TrueForge Container Registry or Codeberg, version 8.2 has your back. WUD now natively supports these registries, making it easier than ever to automate updates across a wider ecosystem of container sources. Whether you’re running private builds or pulling from niche registries, WUD’s growing compatibility ensures you’re never left behind.

Digest Watching: Now Default (Except for Docker Hub)

Security-conscious users, rejoice. Digest watching is now enabled by default across supported registries, giving you an extra layer of confidence that your containers are always pulling the exact image you expect. The only exception? Docker Hub—where limitations in their API still prevent digest-based tracking. For everyone else, this means tighter integrity checks and fewer surprises in production.

Smarter Tag Handling: Precision at Its Finest

WUD 8.2 introduces a refined approach to tag candidate processing, ensuring consistency and predictability when selecting updates. Here’s what’s new:

• Semantic Version Integrity: The tool now preserves the same number of semantic version parts, so 1.2.3 stays 1.2.3—no unexpected jumps or truncations.
• Prefix Preservation: Your original tag prefixes are respected, keeping naming conventions intact.
• Signature Tag Filtering: Signature tags are now ignored where appropriate, reducing noise and focusing on meaningful updates.

These improvements mean fewer false positives and a smoother, more reliable update experience.

Docker Compose Gets a Boost

For Docker Compose users, WUD 8.2 introduces the new wud.compose.file supported label, making it easier to define and manage your Compose configurations. Plus, a pesky issue affecting YAML files with multiple aliases has been squashed, ensuring smoother parsing and fewer headaches.

Enhanced Notifications and Integrations

Staying informed about updates is now more flexible than ever. WUD 8.2 adds:

• Rocket.Chat Trigger: Instantly notify your team on Rocket.Chat when updates are available or applied.
• SMTP Improvements: Add a display name to your “from” address for a more professional touch in email notifications.
• Prometheus Metrics Toggle: Need to disable metrics for compliance or performance reasons? Now you can, with a simple configuration switch.

These enhancements make WUD more adaptable to your workflow, whether you’re running a small home lab or a sprawling enterprise cluster.

A Modern Makeover: Vue 3, Vuetify 3, and TypeScript

Under the hood, WUD has undergone a significant transformation. The web interface has been rebuilt using Vue 3 and Vuetify 3, delivering a faster, more responsive, and visually polished experience. TypeScript now powers the frontend, bringing improved type safety and developer productivity. On the backend, Node.js 24 takes the stage, unlocking the latest language features and performance optimizations. Even the official Docker image has slimmed down, now based on Alpine for a smaller footprint and faster deployments.
