Matrix jobs

Matrix jobs

Matrix jobs execute the same script with different inputs

Matrix jobs are defined using parallel

The matrix keyword under parallel defines variables sets

Hands-On 1/

Cross-compile Go for multiple architectures

1. Extend template to support GOOS and GOARCH:

    .build-go:
      # ...
      parallel:
        matrix:
        - GOOS: linux
          GOARCH: amd64
        - GOOS: linux
          GOARCH: arm64
      script:
      - go build -o hello-${GOOS}-${GOARCH} . \
            -ldflags "-X main.Version=${CI_COMMIT_REF_NAME} -X 'main.Author=${AUTHOR}'"
   

Hands-On 2/2

1. Update the test job:

    test:
      #...
      script:
      - ./hello-linux-amd64
   

2. Check pipeline
