I used to simply use the ‘latest’ version tag, but that occasionally caused problems with breaking changes in major updates.
I’m currently using podman-compose and I manually update the release tags periodically, but the number of containers keeps increasing, so I’m not very happy with this solution. I do have a simple script which queries the Docker Hub API for tags, which makes it slightly easier to find out whether there are updates.
I imagine a solution with a nice UI for seeing if updates are available and possibly applying them to the relevant compose files. Does anything like this exist or is there a better solution?
I use a combination of flux and a python app that checks out everything running on my cluster and keeps me a list of what needs some attention from upgrades and kube-clarity as well. It’s more kubernetes related though.
I combine 3 options:
- Watchtower updates most containers. They never break. If it leads to some breaking, it goes to the second option.
- Update script that update the whole stack from portainer webhook. This did fix the only stack that used to give me issues with watchtower. The other stack is watchtower itself.
- Manual update. Only for Homeassistant. I want to make sure to know about breaking changes. So I update it when I can and I read the patch notes.
It works for my around 100 containers.
I read the changelogs for the apps, and manually update the containers. Too many apps have breaking changes between releases.
Auto update with “latest” version tag, and re-pull to a specific previous version if there are problems. Got too many containers to keep up with individual versions
If you pull ‘latest’ and then want to roll back, how do you know what version you were in before? Is there a way to see what version/tag actually got pulled when you pull latest?
Last time it happened was with one of the newer Nextcloud updates. It was a bit of trial and error, but I eventually went back to a version that worked and I could fix the underlying issue. There should be a list of version tags either on dockerhub or GitHub that list all versions that have been pushed to live and are available to pull
Watchtower auto updates for me.
Sometimes stuff breaks, if it does and I can’t fix it, I’ll just roll back to a backup for that stack and figure it out from there.
