Haskell

This guide covers configuring continuous integration pipelines for Haskell projects.

Build and Test​

In the below example we demonstrate a pipeline that executes cabal commands. These commands are executed inside the Haskell Docker container, downloaded at runtime from DockerHub.

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: test
        type: run
        spec:
          container: haskell
          script: |-
            cabal install --only-dependencies --enable-tests
            cabal configure --enable-tests
            cabal build
            cabal test

Please note that you can use any Docker image in your pipeline from any Docker registry. You can use the official Haskell images, or your can bring your own.

Test Multiple Versions​

You can configure multiple, containerized steps to test against multiple versions of Haskell.

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: test 8
        type: run
        spec:
          container: haskell:8
          script: |-
            cabal install --only-dependencies --enable-tests
            cabal configure --enable-tests
            cabal build
            cabal test

      - name: test 7
        type: run
        spec:
          container: haskell:7
          script: |-
            cabal install --only-dependencies --enable-tests
            cabal configure --enable-tests
            cabal build
            cabal test
