digitalmars.D - has anyone got dmd and/or ldc working on alpine linux in docker?

THere's also no package for dmd/ldc/gdc to install via apk that I 
can find.

Has anyone done this?

LDC 1.13.0 was released with a package for Alpine [1]. But that version 
is quite old

Yes, our company have. I even tried to submit it as a package 
upstream, but haven't got ANY feedback for than 2 months now.

https://github.com/alpinelinux/aports/pull/10107

The way we did it is by using LDC 1.8.0 to bootstrap LDC 1.17.0.
We also build our own dub, because 1) we need it for building, 
and 2) we needed a recent version with support for coverage 
(this: https://github.com/dlang/dub/pull/1755 ).

If you want to give it a quick try, you can look at how we do it:
https://github.com/bpfkorea/agora/blob/adeec783bce88feee4e115b66d11d88813546ecd/Dockerfile

Note that it's currently confined to a single version of LDC, but 
that's a starting point.
In the future I hope that my PR gets merged and I can get rid of 
all my custom setup.

Additionally, Iain Buclaw, GDC maintainer, has done a wonderful 
job at backporting patches for Musl. Since Alpine edge is already 
on GCC 9.x, that would be another way (probably more appropriate 
for upstream) to do bootstrapping.

Nice work! I pinged someone who I saw recently merging PRs, so 
hopefully we will have this properly merged.

Cool! Thanks for that! Question - how have you found alpine 
support generally? As in, do you end up having to jump through 
extra hoops compared to say if you had used a Debian image?

Since I had to make packages to bootstrap the compiler, build dub 
and rdmd, it was much more pain that using the D-provided install 
script, sure.

The main difference is that alpine uses a different libc (Musl), 
and so it needed a few patches in druntime. There are still some 
fixes being made: at this very moment, the last PR that made it 
in druntime was a fix for musl, for example.

But having an image of 10 to 15 mbs is a great improvement over 
the few hundreds of Mb of the Ubuntu (/Debian?) image. If you use 
docker a lot (for deployment or integration tests), I believe it 
is already worth jumping through those hoops. And once the 
package definitions get merged, things will be much simpler.
