history
Project history and usage
Dockcheck is a Bash CLI for checking and optionally applying Docker image updates. Its README frames the tool around selective updates, include and exclude lists, image backups, labels, notifications, pruning, and Compose-aware container recreation.
Project history
The maintainer's project writeup traces the idea to late 2022, when the original goal was to determine whether container images had updates without pulling every image first. The implementation settled on comparing local and remote image digests with help from regclient/regctl, turning a home-server maintenance annoyance into a reusable script.
Adoption history
Dockcheck's adoption is mostly self-hosting and homelab oriented: it is packaged for Homebrew in this batch, but the upstream README still documents direct script installation into a PATH directory and cron-style unattended checks. The README also points Podman users to the podcheck fork, which is a useful signal that its audience overlaps with container tinkerers who manage small fleets outside a full orchestration platform.
How it is used
Common usage is to scan running or stopped containers for newer images, choose which containers to update, pull the selected images, recreate containers or Compose stacks, and optionally prune dangling images afterward. Configuration lives in dockcheck.config beside the script or under ~/.config, and notifications are driven by shell templates plus channel-specific environment variables.
Why package nerds care
Dockcheck is package-nerd interesting because it sits between heavy automated updaters and manual docker compose pull loops. It is a small shell tool built around registry digests, regctl, jq, and Compose conventions, so packaging it gives users a reproducible way to add conservative image-update checks to cron jobs and home servers.
