ln-730-devops-setup

Purpose & Scope

• Does: Auto-detect stack, delegate to workers, verify configuration
• Does NOT: Generate files directly (delegates to ln-731, ln-732, ln-733)

Overview

Supported Stacks

Workflow

Phase 1: Pre-flight Validation

• Verify Docker is installed (

  docker --version

  )
• Verify docker-compose is available
• Check for existing DevOps files (warn if overwriting)

Phase 2: Project Analysis (Auto-detect)

src/frontend/package.json

package.json

*.sln

src/**/*.csproj

requirements.txt

pyproject.toml

appsettings.json

.env.example

.github/workflows/

azure-pipelines.yml

• 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)

Phase 3: Worker Delegation

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

• 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

• Run

  docker-compose config

  to validate syntax
• Check all referenced files exist
• Verify no secrets in committed files

Phase 5: Completion Report

• 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

1. Auto-detect Only: No interactive prompts. Uses detected values or sensible defaults.
2. Idempotent: Check file existence before creation. Warn before overwriting.
3. Parallel Execution: Workers are independent, can run in parallel.
4. Error Recovery: Continue on partial failures, report all issues at end.
5. 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
