  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.

    Thanks for the detailed explanation. Will try to see how it fits my setup when I get a chance, but I have been wanting to move away from Watchtower as it is no longer maintained. Good to know there is an alternative, and from what you describe I like your approach. Having to opt-out of updates in Watchtower never really sat right with me- Watchtower clutter is okay in compose files that actually want something to do with Watchtower…

      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.

      Watchtower as it is no longer maintained

      Not to take away anything from the OP, but there is a fork of Watchtower that is maintained and works a lot better than the OG Watchtower. The original Watchtower in that it would screw up the update fairly regularly. So, if you want to just yolo your updates, that’d be the way to go. If you want a bit more control, DockCheck seems to have that covered. It’s always good to have choices.

  Watchtower hadn’t been updated in like 3 years or something. It’s a dead project.

    What more does it need to do

    It works prefectly

      Stopped working for me with a recent docker cli update. That’s how I even found out it’s totally abandoned.

      I’m not a big fan of running software that has access to the internet once it’s abandoned like this.

        Sorry for spamming in this thread, but if you rely on Watchtower, there’s a maintained fork I recommend: github.com/nicholas-fedor/watchtower

        source

        Is used by literal millions. I’m sure if there was a security issue or would be reported.

        Changes for the reason of making changes doesn’t make sense either

      Not for the latest and future versions of Docker.

      This fork works, though: github.com/nicholas-fedor/watchtower

    There’s a maintained fork, fortunately!

    Your point being that I am not currently using it? Or that I should be looking for alternatives since I am currently using it?

    • madcaesar@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

      I used to use it and switched away because it’s not maintained and I had errors with recent docker cli
