WUD (What’s Up Docker?) is a service that watches your running Docker containers and checks whether newer container images are available for the tags you use. It helps you stay informed about updates without manually tracking image versions.

Key Features

Monitors Docker containers and detects when updated images are published
Compares image versions using semantic versioning when applicable
Notification-oriented workflow to inform you about available updates
Designed to run alongside your existing Docker setup

Use Cases

Track updates for homelab and self-hosted Docker stacks
Monitor production or staging containers for new image releases
Maintain visibility into version drift across multiple containers

WUD is a lightweight companion service for Docker users who want timely awareness of container image updates and a clearer path to keeping stacks current.
