Diun VS dockcheck

Thanks, I used to use it. I moved to using diun to just notify of updates but not apply them though.

https://crazymax.dev/diun/ and docker compose

Similar to Watchtower but without the option to auto-update containers, just notifying is diun. But imo it does that better and more reliable than Watchtower does. You can get notified by Email, Discord, Pushover, Telegram and many more options.

If your apps are container images, then there are tools like diun, watchtower and whatsupdocker, those can watch the image repository (like Docker Hub) and notify you if a new/updated image has been found. Some can even download and auto-update for you, but that comes at some risk of course.

You might want to have a look at https://crazymax.dev/diun/ which is purpose built for what you're trying to do (notify when an update is available, but not install).

Watchtower is inferior to a project like DIUN this way. Because with double you can actually be notified by newer image versions and act accordingly. But automatic updates (which latest is aswell) are bad practice.

diun is very similar to that, but it doesnt auto-update, just notifies but does that very well imo.

I use https://crazymax.dev/diun/ to send notifications of new images. I also hook it into webbooks with CI for mirroring images, but you should be able to use something like portainer webhooks to auto pull images.

As someone who knows just enough about Docker to be able to scratch together a docker-compose.yml every now and again only to promptly forget all the commands I need to ever maintain them going forward, I'm eternally grateful that dockcheck.sh prompts me to do this as a final step whenever I run it.

I’m a simple man. I upgrade everything via dockcheck, verify that everything still works, and if not restore from backup!

And I've personally made a script to selectively auto-update containers, or just check status. With the option to filter or exclude specific containers. Find the project here: mag37/dockcheck

To "mass-check and mass-update" containers from the commandline, dockcheck is very light and useful. A simple dockcheck.sh -a -p for example would check all deployed containers for image updates and if there are any, pull them, then restart the container and at the end, cleanup unused images to free up diskspace. There is also a version with a web interface, DCW.

I haven’t gone the watchtower route, since I’d prefer to review changes myself (or let’s be honest - others’ reactions to the changes). Instead. I’ve been using a combo of diun and dockcheck (https://github.com/mag37/dockcheck ). Diun lets me know when containers have changed and dockcheck lets me cherry pick what I upgrade.

If you want to update images, try dockcheck or DCW.
