dockcheck is simple CLI tool to simplify keeping track of and updating your containers. Selective semi/fully auto updates, notifications on new versions and much more.

Another 6 months have passed and a bunch of updates have been made. The most recent ones are multi-threaded/asynchronous checks to greatly increase speed, notifications on new dockcheck release for those who run scheduled unattended checks, osx and bsd compatibility changes, prometheus exporter to push stats to eg. Grafana and more.

I'm happy to see the project still being used and improved by its users as I thought other great tools (dockge, wud, watchtower and others) would replace it.

As it's been a while I'll try to list the features:

Checks all your containers for new updates, without pulling.
Manually select which containers or choose all.
Either run it to auto update all, or not update any and just list results.
Tie it to notify you on new updates.
- Templates: Synology DSM, mSMTP, Apprise, ntfy.sh , Gotify , Pushbullet , Telegram , Matrix, Pushover , Discord.
- Enrich with urls to container release notes.
Optionally export metrics to Prometheus to show how many images got updates available in a graph.
Other misc options as:
- Use labels to only update containers with label set.
- Use a N days old option to only update images that have been stable release N days.
- Auto prune dangling images.
- Include stopped containers.
- Exclude specific containers.

I've got to thank this community for contributing with donations, ideas, surfacing issues, testing and PRs. It's a joy!

This is a great tool, thanks for the continued support.

Personally, I don't actually use dockcheck to perform updates, I only use it for its update check functionality, along with a custom plugin which, in cooperation with a python script of mine, serves a REST API that lists all containers on all of my systems with available updates. That then gets pulled into homepage using their custom API function to make something like this: https://imgur.com/a/tAaJ6xf

So at a glance I can see any containers that have updates available, then I can hop into Dockge to actually apply them on my own schedule.
