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?
Maybe take a look at Diun or Watchtower
I use Diun and ntfy to get push notifications about new docker image versions on my smartphone. Other options include notifications for Discord, mail, MQTT, Slack, Webhook and more.
Was not aware of Diun, will check out!
Taking a brief look at that blog post, the author doesn’t know that wt can be set to only notify… Or that wt can be set to act at specific date or time… It’s like they never looked at the wt env variables at all, just yolo defaults and then complain that it doesn’t do what they want out of the box (‘because my settings are the best and they should clearly be the default for everyone!’). For someone who spent much time exploring other options and complaining, they didn’t take ~10 minutes to learn that the initial issue was indeed themselves.
(I use wt and set up many options to avoid these issues, successfully)
