    KEY_PATH="./github_key.pem" \
    REGISTRY="ghcr.io/<GITHUB_USERNAME>/go-github-app"

Running

• 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
