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.json engines or use node -v
.NET: Read from *.csproj TargetFramework
Python: Read from pyproject.toml or runtime.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 Task tool)
    |         Input: stack config, versions
    |         Output: Dockerfile.*, docker-compose.yml, .dockerignore
    |
    +---> ln-732-cicd-generator (via Task tool)
    |         Input: stack config, detected commands
    |         Output: .github/workflows/ci.yml
    |
    +---> ln-733-env-configurator (via Task tool)
              Input: detected environment variables
              Output: .env.example, .env.development, .gitignore updates

Error Handling:

If worker fails, log error and continue with others
Report all failures at the end
Suggest manual fixes for failed components

Phase 4: Configuration Verification

Verify generated configuration:

Run docker-compose config to 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 frontend
Dockerfile.backend - Multi-stage build for backend
docker-compose.yml - Service orchestration
docker-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)
.gitignore updates - 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.

Definition of Done

[ ] Pre-flight validation passed
[ ] Stack auto-detected successfully
[ ] All workers completed (or failures documented)
[ ] docker-compose config validates successfully
[ ] No secrets in generated files
[ ] Completion report displayed
