Ruby

This guide covers configuring continuous integration pipelines for Ruby projects.

Build and Test

In the below example we demonstrate a pipeline that executes bundle install and rake commands. These commands are executed inside the ruby Docker container, downloaded at runtime from DockerHub.

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: test
        type: run
        spec:
          container: ruby
          script: |-
            bundle install --jobs=3 --retry=3
            rake

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

Test Multiple Versions

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

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: test 2.4
        type: run
        spec:
          container: ruby:2.4
          script: |-
            bundle install --jobs=3 --retry=3
            rake

      - name: test 2.3
        type: run
        spec:
          container: ruby:2.3
          script: |-
            bundle install --jobs=3 --retry=3
            rake
