Usage

Build image

latest:

docker build \
  --build-arg GHC_VERSION=9.8.2 \
  --build-arg CABAL_VERSION=3.10.3.0 \
  --build-arg STACK_VERSION=2.15.5 \
  -t ghc-musl \
  -f latest.Dockerfile .

version:

docker build \
  -t ghc-musl:MAJOR.MINOR.PATCH \
  -f prior/MAJOR.MINOR.PATCH.Dockerfile .

For MAJOR.MINOR.PATCH GHC versions 8.8.4, 8.10.1 and ≥ 8.10.4.

👉 See the Version Matrix for detailed information.

Run container

self built:

docker run --rm -ti ghc-musl[:MAJOR.MINOR.PATCH]

from Quay:

docker run --rm -ti quay.io/benz0li/ghc-musl[:MAJOR[.MINOR[.PATCH]]]

from Docker Hub:

docker run --rm -ti docker.io/benz0li/ghc-musl[:MAJOR[.MINOR[.PATCH]]]

from GitLab (b-data GmbH):

docker run --rm -ti glcr.b-data.ch/ghc/ghc-musl[:MAJOR[.MINOR[.PATCH]]]

As of 2023‑08‑12, the images (versions 9.2.8, 9.4.6, 9.6.2 and later) also include the Haskell Tool Stack (Stack).

On 2024‑02‑23, the binary distribution of GHC version 9.8.2 was released for Alpine Linux (AArch64).
❗ Use flags --no-install-ghc --system-ghc with Stack (GHC versions < 9.8.2) to ensure that only the GHC available in the container is used.

Dev Containers

The default Dev Container is meant to work on this repository.

Any other configuration is a custom GHC container based on GHC musl.
