.NET Pipeline to PCF

Creating a simple test and build pipeline

In project root, create a folder .circleci and place config.yml within it.

Below example, includes CloudFoundry manifest file. Remove if necessary.

Below example is an example .NET config. Replace with your stack as necessary.

In config.yml, place the following jobs and workflow:

version: 2
jobs:
  test:
    docker:
      - image: 'microsoft/dotnet:2.2-sdk'
        environment:
          DEBIAN_FRONTEND: "noninteractive"
    steps:
      - checkout
      - run:
          name: test
          command: dotnet test
  build:
    docker:
      - image: 'microsoft/dotnet:2.2-sdk'
        environment:
          DEBIAN_FRONTEND: "noninteractive"
    steps:
      - checkout
      - run:
          name: build
          command: |
            build_output="/tmp/build-output"
            artifacts_path="./artifacts"
            version=$CIRCLE_SHA1
            mkdir -p $build_output
            mkdir -p $artifacts_path
            cp manifest.yml $build_output
            dotnet publish src/MyApp --configuration Release \
                --output $build_output/src/MyApp/bin/Release/netcoreapp2.2/publish
            tar -C $build_output/ -cvzf $artifacts_path/myapp-$version.tgz .
      - store_artifacts:
          path: artifacts
      - persist_to_workspace:
          root: artifacts
          paths:
            - myapp-*.tgz

workflows:
  version: 2
  deployment-pipeline:
    jobs:
      - test
      - build:
          requires:
            - tests

Example build pipeline

Deploying to CloudFoundry

In config.yml, add the following steps:

...
jobs:
    deploy-to-pcf:
        docker:
        - image: 'microsoft/dotnet:2.2-sdk'
            environment:
            DEBIAN_FRONTEND: "noninteractive"
            EXTRACT_DEST: /tmp/extracted-archive
        steps:
        - attach_workspace:
            at: artifacts
        - run:
            name: Install CF CLI
            command: |
                apt-get update
