Oh I am not sure we are talking about the same thing. This 
CircleCi image is intended to be used for CircleCi _only_ and 
there's a lot of stuff you probably don't want to have in your 
production container:

https://github.com/wilzbach/dlang-docker/blob/master/circleci/template.docker

However, I also added dlang2/{dmd,ldc,gdc}-ubuntu images 
recently. Here's an example app built with DUB:

https://github.com/wilzbach/dlang-docker/blob/master/example-app/Dockerfile

However, note that this will install the respective D compiler in 
your image which typically actually don't need for your 
application (so again it's more intended for CI usage)
Hence, for my things I use `-static` and just COPY the binary 
into the docker image.
Here's an example of an Open-Source application, which I 
maintain, that does so:

https://github.com/dlang-tour/core/blob/master/Dockerfile
https://github.com/dlang-tour/core/blob/master/dub.sdl

It's a pity that D doesn't support Musl (a light-weight 
alternative to glibc) yet, but that might change soon [1].
Anyhow for now you can use glibc on alpine, e.g.:
