⁠haskell_build_env

Alpine Linux based Haskell build environment for static binaries with musl.

Image is based on the examples from the FP Complete Haskell static compilation blog post https://www.fpcomplete.com/blog/2016/10/static-compilation-with-stack⁠ .

⁠Usage

From your project directory run:

docker run --rm -v $(pwd):/usr/src/build -v ${HOME}/.stack:/root/.stack -w /usr/src/build -it q4uw/haskell_build_env

This will:

• Give you a bash prompt in the container
• Mount your project directory in the docker container
• Mount your local stack home in the container to make use of artifact caching
• Set the working directory to the project root

⁠Static compilation

To statically compile a binary inside the containers project root:

stack install --local-bin-path /usr/src/build/dist --ghc-options '-optl-static -fPIC -optc-Os'

This above command will place the binary in the ${PROJECT_ROOT}/dist directory.

⁠Compress the binary

You can further compress the binary which significantly reduces the size using UPX.

upx --best --ultra-brute dist/${BINARY_NAME}
