Phase 2: Add Go Environment

• Setup Go environment (version 1.21.5)
• Install dependencies

Phase 3: Add Build

• Build Go application
• Create binary

Phase 4: Add Tests

• Run unit tests with coverage
• Generate test reports

Phase 5: Add Static Analysis

• Run golangci-lint
• Run go vet
• Check code formatting

Phase 6: Add Artifacts

Running Locally

# Build
go build -o bin/app ./cmd/webapp

# Test
go test -v ./cmd/...

# Run
./bin/app
# or
PORT=8090 ./bin/app

GitHub Actions

All workflows are located in .github/workflows/ directory. Each phase builds upon the previous one, demonstrating progressive CI/CD implementation.

To use a specific phase:

1. Enable the desired workflow
2. Push changes to trigger the workflow
3. View results in GitHub Actions tab

Environment Variables

• PORT - Server port (default: 8090)

Endpoints

• / - Home page
• /health - Health check endpoint
• /version - Version information
