Argus VS Diun

Argus sounds like it will do a lot/most/all of what you're looking for. Super easy to set up with Docker. I had it running for quite a while but just moved everything to either Github release notification emails or diun (docker image update notifier). No real reason for my switch besides laziness/familiarity. Check it out!

We've recently implemented https://github.com/release-argus/Argus to keep track of all docker images that need regular upgrades.

https://github.com/release-argus/Argus is another alternative

Agreed. Does everything watchtower does and gives you a web page to view configuration of whatsupdocker and available container updates. Can monitor only or upgrade. Also has a docker compose trigger to perform upgrades. Might also look at Argus to monitor application versions.

Fantastic! This is exactly what I’ve been looking for. Link for anyone interested - check out the demo.

Take a look at Argus. I use it to monitor the application version (not a container tag). I get notifications via mailrise (SMTP gateway for apprise) which then go to Gotify and Discord. I have webhooks setup to run scripts so I can approve the update from the Argus app to automate the update. You can also have it set to auto approve.

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.
