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 just subscribe with RSS to the releases page on github of each project
Thanks!
If im doing this right, the url is just the releases page for the repo with a .atom at the end. So for Vaultwarden it is https://github.com/dani-garcia/vaultwarden/releases.atom
GitHub has the option of emailing you on releases etc. by email.
You can also hook it to RSS https://stackoverflow.com/questions/7353538/setting-up-a-github-commit-rss-feed
Yeah, depending on the branch I’ve found that method not to be too reliable. openrss offers branches for RSS feeds for commits on every branch though: e.g. https://openrss.org/github.com/octokit/octokit.rb/commits/main
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
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.
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)
While of course Watchtower can be configured to not update and only notify there is also a nice, lightweight alternative out there that is built only for image update notifications: Diun.
I think he looked at it.
I use renovate myself. Via a cron job against a self hosted gitea instance.

Works for many dependency types including docker images. You can also have it pin non version tags (using digests).
