If you want a small image, Alpine Linux is definitely the way to 
go.
You can find `gcc-gdc` (however it's an old frontend, v2.076) in 
Alpine Linux's main repository.

Additionally, if you can find the latest `ldc` in the `testing` 
repository 
(https://forum.dlang.org/thread/oznltcuropwzxaakptdy@forum.dlang.org).

I intend to add DMD, just didn't have to get to it yet. If you 
want to do it yourself, here's the APKBUILD:
