Hi all,

I am in the process of rewriting my helm chart for 389ds (stay tuned, I'll send
another mail once it is ready), and noticed the lack of recent tags for the
container images:
Oh, nice! Looking forward to it! 

https://hub.docker.com/r/389ds/dirsrv only has 2.1, 2.2 and latest. 2.2 and
latest are 8 months old.

https://quay.io/repository/389ds/dirsrv?tab=tags only has latest and c9s without
any version tags (or I did not find them?).

Would it be possible to publish the tags more often? And maybe publish all patch
versions (2.2.1, 2.2.6, ...) in addition?
Yes, it's possible.

Using "latest" or "stable" is not a good idea for container workloads, as it
does not allow rollbacks in case of errors or changed behaviour. Rolling back is
easy using helm charts, but only if the image can be changed back from say 2.2.6
to 2.2.5 by helm. When using stable or 2.2 or similar, the new image will be
fetched and the old one discarded, so it will be lost and no longer usable.
Yes, that's understandable. As you already found out, we have a split brain situation with images in different registries, so I wanted to sort this out first. But I can tags to quay.io repos.
One thing to keep in mind though: those minor releases might be less tested. I chose to follow packages in Fedora rather than 389-ds-base versions because these packages go through testing with FreeIPA and OpenQA. But I guess with helm and deployments rollback this is less of an issue.


Having usable tags would really be helpful, so I would be happy if this could be

Have a nice day, everyone!
