ln-732-cicd-generator
Type: L3 Worker Category: 7XX Project Bootstrap Parent: ln-730-devops-setup
Generates GitHub Actions CI pipeline for automated testing and validation.
Purpose & Scope
Creates CI/CD workflow for GitHub:
- Does: Generate .github/workflows/ci.yml with lint, test, build, docker jobs
- Does NOT: Configure deployment, manage secrets, set up CD pipelines
Inputs
| Input | Source | Description |
|---|---|---|
| Stack Type | ln-730 coordinator | backend-dotnet, backend-python |
| Versions | Auto-detected | Node.js, .NET or Python versions |
| Frontend Path | Auto-detected | Path to frontend directory |
| Build Commands | Auto-detected | npm scripts, dotnet/pytest commands |
Outputs
| File | Purpose | Template |
|---|---|---|
.github/workflows/ci.yml | Main CI pipeline | github_ci_dotnet.template.yml or github_ci_python.template.yml |
Workflow
Phase 1: Stack Analysis
Determine which template to use:
| Detection | Backend Template |
|---|---|
.sln or .csproj present | github_ci_dotnet.template.yml |
requirements.txt or pyproject.toml present | github_ci_python.template.yml |
Detect commands:
- Frontend: Read scripts from package.json (lint, build, test)
- .NET: Standard dotnet restore/build/test
- Python: pip install, ruff lint, pytest
Phase 2: Variable Substitution
Replace template variables:
| Variable | Source | Default |
|---|---|---|
{{NODE_VERSION}} | package.json engines | 22 |
{{DOTNET_VERSION}} | *.csproj TargetFramework | 9.0.x |
{{PYTHON_VERSION}} | pyproject.toml | 3.12 |
{{FRONTEND_PATH}} | Directory detection | src/frontend |
Phase 3: Directory Creation
Create .github/workflows/ directory if not exists.
Phase 4: File Generation
Generate ci.yml from selected template:
- Check if workflow already exists (warn before overwrite)
- Apply variable substitution
- Write to
.github/workflows/ci.yml - Validate YAML syntax
Generated Pipeline Structure
Jobs Overview
| Job | Purpose | Dependencies |
|---|---|---|
| frontend | Lint, build, test React/Vite | None |
| backend | Build, test .NET or Python | None |
| docker | Build images, health checks | frontend, backend |
Frontend Job Steps
- Checkout code
- Setup Node.js with caching
- Install dependencies (
npm ci) - Run linter (
npm run lint) - Build application (
npm run build) - Run tests (
npm test)
Backend Job Steps (.NET)
- Checkout code
- Setup .NET SDK
- Restore dependencies (
dotnet restore) - Build (
dotnet build) - Run tests (
dotnet test)
Backend Job Steps (Python)
- Checkout code
- Setup Python with pip caching
- Install dependencies (
pip install -r requirements.txt) - Run linter (
ruff check) - Run tests (
pytest)
Docker Job Steps
- Checkout code
- Build images (
docker compose build) - Start containers (
docker compose up -d) - Wait for startup (30 seconds)
- Health check frontend (port 3000)
- Health check backend (port 5000/8000)
- Show logs on failure
- Stop containers (
docker compose down)
Triggers
| Event | Branches |
|---|---|
| Push | main, develop |
| Pull Request | main |
Best Practices Applied
| Practice | Implementation |
|---|---|
| Dependency caching | npm cache, pip cache |
| Pinned versions | actions/checkout@v4, setup-node@v4 |
| Parallel jobs | frontend and backend run in parallel |
| Fail fast | docker job waits for both to succeed |
| Clean up | docker compose down runs always |
| Debug support | logs shown on failure |
Quality Criteria
Generated workflow must:
- Pass YAML syntax validation
- Use pinned action versions (not
@latest) - Include dependency caching
- Have health checks for docker job
- Clean up resources on completion
Critical Notes
- GitHub Actions Only: This skill generates only GitHub Actions workflows. No Azure/GitLab support.
- Template-based: Use templates from references/. Do NOT hardcode workflow contents.
- Idempotent: Check if .github/workflows/ exists. Warn before overwriting ci.yml.
- Version Detection: Use detected versions, not hardcoded defaults.
