I have created a docker image.
However the image size is not small (~500MB).
I wonder if others have a suitable dockerfile.
All i want is to install the current dmd release.

Does somebody have something similar?

My dockerfile:

```

RUN apt-get update &&  apt-get install curl build-essential -y \

\
   && dpkg -i "dmd.deb" \
   && rm "dmd.deb"

If you really need small images, you could switch to Alpine, but 
MUSL c could lead to headaches ;)

There are also the official docker images 
https://hub.docker.com/u/dlang2

What is your goal? Do you want to compile s.th. in your docker 
image? Then you can have a layered docker file to reduce the size.

Kind regards

I just wanted to know, whether i am doing something completely 
wrong.
Oh i haven't found these docker images. I did only search for 
"dlang" not "dlang2".
Thanks a lot!

You might also use debian:slim as base image, which might reduce 
the size.

Kind regards

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:
