Building GitHub Apps with Golang

Quick Start

To use this repository as starter for your project you can run configure_project.sh script, which sets up all variables and file names. This way you can avoid configuring and renaming things yourself:

./configure_project.sh \
    APP_ID="54321" \
    INSTALLATION_ID="987654321" \
    WEBHOOK_SECRET="verysecret" \
    KEY_PATH="./github_key.pem" \
    REGISTRY="ghcr.io/<GITHUB_USERNAME>/go-github-app"

Running

make container  # Builds containerized application
make run        # Runs container at localhost

# From another terminal:
curl http://localhost:8080/api/v1/github/pullrequests/octocat/hello-world

Testing

Test are run inside container image, equivalent to the container in which the application runs. To run tests:

make test

CI/CD

Predefined CI/CD uses GitHub Actions:

• Build, Test, Lint Workflow (build.yaml):

  • Builds binary and container image
  • Runs tests and generates code coverage report
  • Performs SonarCloud code analysis
  • Sends coverage starts to CodeClimate

• Release Workflow (release.yaml, triggered on tag creation):

  • Builds container image
  • Pushes the image to GitHub container registry
