Alpine-LDC

A compilation for D code using LDC running on Alpine Linux. Perfect for multi-stage docker builds or playing with light environments. Dub is also included in this container.

Building

This is a pretty regular docker build. The appropriate LDC version and the latest version of Dub that the dub-registry knows about will be pulled down during the container build process. You can also pull my latest image from docker hub with docker pull andrewbenton/alpine-ldc:latest.

Optionally, a build argument can be supplied to set the version of LDC to pull. The default is v1.9.0.

Example:

export LDC_VERSION=1.9.0
docker build --build-arg "LDC_VERSION=${LDC_VERSION}" -t "alpine-ldc:${LDC_VERSION}" .

# or

make LDC=1.9.0

Running

Once the docker container is built or pulled, running it is easy.

$ docker run -it --rm alpine-ldc:1.9.0
/ # cd /tmp
/tmp # echo 'void main() { import std.stdio; writeln("hello, world!"); } ' > test.d
/tmp # ldc2 test.d -of test
/tmp # /tmp/test
hello, world!
/tmp # exit

Example

Examples require that you have docker installed on your machine. This is the simplest example.

Known issues

• For whatever reason, the interactive dub init prompt doesn't quite work.
• The libc version used is musl, which isn't as well supported in druntime as glibc.
