ln-730-devops-setup
Type: L2 Domain Coordinator Category: 7XX Project Bootstrap Parent: ln-700-project-bootstrap
Coordinates DevOps infrastructure setup by delegating to specialized workers.
Purpose & Scope
Orchestrates the complete DevOps setup for a project:
- Does: Auto-detect stack, delegate to workers, verify configuration
- Does NOT: Generate files directly (delegates to ln-731, ln-732, ln-733)
Overview
| Aspect | Details |
|---|---|
| Input | Project directory with source code |
| Output | Docker, CI/CD, environment configuration |
| Workers | ln-731 (Docker), ln-732 (CI/CD), ln-733 (Environment) |
| Mode | Auto-detect (no user prompts) |
Supported Stacks
| Component | Option 1 | Option 2 |
|---|---|---|
| Frontend | React/Vite + Nginx | - |
| Backend | .NET 8/9 | Python (FastAPI/Django) |
| Database | PostgreSQL | - |
| CI/CD | GitHub Actions | - |
Workflow
Phase 1: Pre-flight Validation
Check required tools and project structure:
- Verify Docker is installed (
docker --version) - Verify docker-compose is available
- Check for existing DevOps files (warn if overwriting)
Output: Validation report or STOP with instructions
Phase 2: Project Analysis (Auto-detect)
Detect project stack automatically:
| Detection | Method | Files to Check |
|---|---|---|
| Frontend | Package.json presence | src/frontend/package.json, package.json |
| Backend.NET | .csproj/.sln presence | *.sln, src/**/*.csproj |
| Backend Python | requirements.txt/pyproject.toml | requirements.txt, pyproject.toml |
| Database | Connection strings in code | appsettings.json, .env.example |
| Existing CI/CD | Workflow files | .github/workflows/, azure-pipelines.yml |
Version Detection:
- Node.js: Read from
package.jsonengines or usenode -v - .NET: Read from
*.csprojTargetFramework - Python: Read from
pyproject.tomlorruntime.txt - PostgreSQL: Default to latest stable (17)
Output: Stack configuration object with detected versions
Phase 3: Worker Delegation
Delegate to workers in parallel (independent tasks):
ln-730 (Coordinator)
|
+---> ln-731-docker-generator (via Skill tool)
| Input: stack config, versions
| Output: Dockerfile.*, docker-compose.yml, .dockerignore
|
+---> ln-732-cicd-generator (via Skill tool)
| Input: stack config, detected commands
| Output: .github/workflows/ci.yml
|
+---> ln-733-env-configurator (via Skill tool)
Input: detected environment variables
Output: .env.example, .env.development, .gitignore updatesError Handling:
- If worker fails, log error and continue with others
- Report all failures at the end
- Suggest manual fixes for failed components
Invocations:
Skill(skill: "ln-731-docker-generator", args: "{projectPath}")
Skill(skill: "ln-732-cicd-generator", args: "{projectPath}")
Skill(skill: "ln-733-env-configurator", args: "{projectPath}")Phase 4: Configuration Verification
Verify generated configuration:
- Run
docker-compose configto validate syntax - Check all referenced files exist
- Verify no secrets in committed files
Output: Verification report
Phase 5: Completion Report
Generate summary:
- List all created files
- Show detected stack configuration
- Provide next steps for user
Generated Files
Docker (ln-731)
Dockerfile.frontend- Multi-stage build for frontendDockerfile.backend- Multi-stage build for backenddocker-compose.yml- Service orchestrationdocker-compose.override.yml- Development overrides (optional).dockerignore- Build context exclusions
CI/CD (ln-732)
.github/workflows/ci.yml- Main CI pipeline
Environment (ln-733)
.env.example- Template with all variables.env.development- Development defaults.env.production- Production template (placeholders).gitignoreupdates - Secrets protection
Critical Notes
- Auto-detect Only: No interactive prompts. Uses detected values or sensible defaults.
- Idempotent: Check file existence before creation. Warn before overwriting.
- Parallel Execution: Workers are independent, can run in parallel.
- Error Recovery: Continue on partial failures, report all issues at end.
- Version Pinning: Use detected versions, not hardcoded values.
TodoWrite format (mandatory):
- Invoke ln-731-docker-generator (pending)
- Invoke ln-732-cicd-generator (pending)
- Invoke ln-733-env-configurator (pending)
- Verify configuration (pending)
- Generate completion report (pending)Worker Invocation (MANDATORY)
| Phase | Worker | Context |
|---|---|---|
| 3a | ln-731-docker-generator | Shared (Skill tool) — Dockerfiles, docker-compose,.dockerignore |
| 3b | ln-732-cicd-generator | Shared (Skill tool) — CI/CD pipeline configuration |
| 3c | ln-733-env-configurator | Shared (Skill tool) — environment files and.gitignore |
All workers: Invoke via Skill tool — workers see coordinator context.
Definition of Done
- Pre-flight validation passed
- Stack auto-detected successfully
- All workers completed (or failures documented)
docker-compose configvalidates successfully- No secrets in generated files
- Completion report displayed
