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.

Yup, there is a historic reason.
This project solely started because we needed a specific CircleCi image for DMD to speed-up PR builds and fix issues with the normal CircleCI default docker image.
As a test I added the -ubuntu repos to see whether it might be enough for people as a replacement for the previous docker channel which went silent at that time and wanted to keep a clear separation from the CircleCi build images.

Yep, I'm aware and now that people have requested amazonlinux and other images, it really makes sense to switch to that.
I will adapt the build setup to this.

Well, I simply never got around building the Alpine images.

Well, I simply never got around building the Alpine images.

For reference, Alpine now offers relatively up-to-date images in community/{dmd,ldc} and main/gcc supports GDC, so I would just remove those images.
