Yes, I found the issue on Github regarding the images. I already commented my ideas.

That would be really nice.

Basically I would like to have **one** usable image with the tags. If this is
based on Fedora, C9s or openSUSE does not matter much to me (remember,
container, I do not need to do anything inside the container normally :-) ). So
if you just follow the Fedora ones as they are tested the most that would be
fine for me.

I agree. Also maintaining different images for different distributions adds maintenance burden. So I'd like to consolidate images and tags, and provide a solution that makes sense. 

 

The setup aka environment variables etc. should be the same on all of the
images, as they are interpreted by the dscontainer binary that comes from
389ds-base if I understood this correct?

At least 2.2.x and 2.3.x have the same dscontainer entrypoint. So yes, they are the same. 

Kind Regards,
Johannes
