dockcheck is a Bash CLI tool that checks running Docker containers for newer image versions and can update them automatically, without pre-pulling images. It supports interactive or unattended operation with notifications, image backups, include/exclude lists, autoprune, and Home Assistant integration.
Use cases
- check which docker containers have image updates without pulling
- automatically update docker containers via cron
- get notified when docker image updates are available
- backup old docker images before updating containers
- prune old docker images after updating
- unattended docker image updates for homelab
When to choose
- you run Docker on a homelab or server and want lightweight shell-based update automation
- you want update checks without consuming Docker Hub pull limits
- you need notifications (Apprise, Home Assistant, etc.) when updates are available or applied
When to avoid
- you use Podman instead of Docker (use the podcheck fork)
- you need full orchestration-level rolling updates across a cluster (use Watchtower alternatives or Kubernetes tooling)
- you need a GUI or web dashboard for container management
