Questions regarding docker repositories

[dgellow]

Hey there,

Is there a reason to have one image per base-image, with a distinct name? The common approach with public Docker images is to have one repository name such as dlang2/dmd and use tags like dlang2/dmd:ubuntu, dlang2/dmd:alpine, dlang2/dmd:2.091.1-ubuntu, etc for versions and base images.

Meaning that on docker hub you would have only 3 repositories to manage:

• dlang2/dmd
• dlang2/ldc
• dlang2/gdc

Not that the current situation is broken, but it goes a bit against what I would expect (e.g: nginx image, to illustrate what I mean https://hub.docker.com/_/nginx?tab=tags).

Also, I see that the alpine images don't have tags https://hub.docker.com/r/dlang2/dmd-alpine/tags. Is that expected? That looks like a bug.
