TL;DR: is there an app that can alert me when a new version of some other app is available?
I have about 12 - 15 services (freshrss, heimdall, photoprism, Wordpress, etc) running using docker compose spread across 4 hosts. Through my self-hosting journey I’ve been burned a few times using “latest” images so I now pin app image versions within compose.
The problem then becomes that every couple of weeks, I have to go out to different GitHub’s, docker hub, etc. to see if a new update for that service is available. It gets a bit tedious with 12-15 services every couple of weeks so I need a centralized and more efficient way of “keeping up”.
Is there some type of app that can track whether an app/service has a new version available? Ideally it can send me some type of notification, self-hostable, and ideally not Portainer?
I selfhost an instance of ntfy and changedetecttion.
Ntfy is for simple push notifications from absolutely anything, even just curl.
Changedetection is for detecting changes on websites, prices, is something in stock, … It supports ntfy for push notifications so I just add the releases page from github to changedetection and then I get a push notification on my phone when anything gets an update.
I use diun and rss feeds. So far I’ve had different levels of success with different services.
For example for Immich the RSS is a lot more useful because it lets you know when you need to run manual steps.
Watchtower will automatically update docker containers.
That will just pull the latest image though right? I.e., if you explicitly have a container on a tag for v1.2.3, it wouldn’t upgrade you when v1.2.4 is released right?
Yes, but I believe it can be configured for notifications as well, I just never needed that.
RSS feeds
Love that username tho!! Yeah might just do RSS. I already run FreshRSS and it’s ability to filter stuff would probably come in handy too
