Bra grej! Följer.

So true 😂 Both at work and private side projects 👏

Oh that’s very kind of you! There’s an AUR package and a brew already, don’t know if other packages is necessary tbh :)

Though some people have suggested they’d like a docker container - which I should try to spend some time on in the future.

Oh nice, yeah I havn’t thought about suggesting a systemd-service thats neat! If you’d like you could contribute it as a discussion/suggestion/PR if you land on liking it, thatd be lovely.

With the image backups in the next release you could maybe even build some kind of auto rollback functionality.

Sadly no, only within the scope of the tag specified in the compose.

Renovate, WUD or Diun might be other options for that!

Thank you. I hope you can find some usefulness in it. You can also do things by compose labels. As well as dynamically at runtime. Either interactively or as arguments.

This question is usually asked a lot.

This started as a project to prove that you could check for updates without first pulling every new image to compare against, while that’s not why it kept get getting traction my original answer to this question still seems true:

From Watchtower Docs - Arguments

Due to Docker API limitations the latest image will still be pulled from the registry.

And:

Do not pull new images. When this flag is specified, watchtower will not attempt to pull new images from the registry. Instead it will only monitor the local image cache for changes

It’s also a different approach. With dockcheck you’d run it and then make the choice what you’ll update there and then. Selectively choosing exactly what containers to update at the moment. Or have it completely unattended auto update a selection of images.

With the notifications, you can get notified and then have a sitdown and auto-update what you choose.

It’s just different workflows and options.

The upcoming release will also add a new option to backup the image being updated and then autoprune old backups after N days. To allow for easy rollback if a new image breaks.

A bit old, but the section should be alright still.

Hey, I wrote a simple intro recently from guiding two friends into Fedora KDE without any previous knowledge. Its just an introduction really, but covers some basics.

https://mag37.org/posts/guide_newtolinux/

It does not cover dual booting though. As they both decided to fully swap after brief testing.

Others already mentioned Ventoy and that bricking isn’t really a risk - the worst you’d encounter is a complete wipe and restart so make sure you’ve got things backed up either way.

Thank you! Yeah I’m the same - if the first thing I see on a project page is some picture or video or output of what it’s about I’m much more intrigued to read on.

Tooting my own horn here and I know it’s not a 1-1 replacement, but as others mentioned some great alternatives (diun, cup, wud) I’d like to suggest dockcheck.

Thank you for the update!

FYI: The first URL of the new page hits a 404 due to a faulty trailing space, the URL being hit is: https://news.elenarossini.com/%20

The correct url without trailing space:

Very nice! Now posted here: https://github.com/mag37/dockcheck/discussions/146

Thats really nice! Thank you so much for the writeup.

Would you mind if I added this as a discussion (crediting you and this post!) in the github project? Or if you’d like to copypaste it yourself to get the credit and be a part of the discussion.

It’s a different approach. This project started as a proof of concept - just to show that it’s possible to check for updates without pulling the whole image first (which is how Watchtower does it).

Then it evolved to orchestrate granular automatic updates with a bunch of extra functionality - while still adhering to the core goal of keeping it simple and lightweight.

Thank you! Oh! That’s pretty cool, do you mind sharing bits of how this is done? Would be nice to incorporate into a notify-template in the future.

Thank you!

I sadly don’t have too much insights in the other alternatives, I try to not compare too much - maybe I should study them a bit more to understand the wider picture. There’s a few more I forgot to mention; renovate and dependabot.

While I think all those tools are great and have functionality that my project cant fulfill - I strive to keep dockcheck simple and lightweight. Options and functionality have been bolted on bit by bit while still trying to have it as simple as possible in its core functions - so a user could just download the main script dockcheck.sh and run it to list updates and optionally update. Everything else is optional, extras.

I guess it depends on what you’re looking for. If you’d like a GUI or more in depth setup or reporting - I’d look elsewhere, but if you’d like simplicity and maybe schedule it to notify you when there’s updates available - my project may be the thing.

So my answer would be yes: if you’re running docker compose this project is very newbie friendly and easy to get going!
