📋 MIGRATION SUMMARY - Legacy Docker to Foundation

Date: 2025-10-04 Status: ✅ COMPLETE Location: 2 - FOUNDATION/03_INFRA/03_05_containerization/

✅ COMPLETED MIGRATION

🎯 Phase 1: MkDocs Service (PROMPT 1)

Location: 03_06_06_mkdocs_service/

Migrated Components: - ✅ Dockerfile with Python 3.11 + MkDocs Material - ✅ docker-compose.yml with volume mounts to 07_META/03_documentation - ✅ requirements.txt with all plugins - ✅ Automatic hierarchy scanner (discover_hierarchy.py) - ✅ Navigation generator (generate_nav.py) - ✅ Build script (build.sh) - ✅ .env.example for configuration - ✅ Complete README

Features: - 🔄 Live reload on file changes - 📂 Automatic scanning of XX_YY_ZZ directory structure - 🎨 Dynamic navigation generation - 💾 Cache persistence for faster rebuilds - 📚 Integration with legacy docs at 07_META/03_documentation

Port: 8000

🎯 Phase 2: Services Stack (PROMPT 2)

Location: 03_06_07_services_stack/

Migrated Components:

PostgreSQL Service

  • ✅ Dockerfile (postgres:16-alpine)
  • ✅ Schema initialization from legacy (init/001-init.sql)
  • ✅ Health checks
  • ✅ Persistent volume

Schemas: - audiolab - Plugins, components, presets - metadata - Documentation and diagrams - analytics - Build metrics

Port: 5432

FossFLOW Service

  • ✅ docker-compose configuration
  • ✅ Volume mounts for icons and templates
  • ✅ Export integration to 07_META/03_documentation/docs/3_diagrams
  • ✅ Depends on PostgreSQL health

Port: 8080

MkDocs Integration

  • ✅ Included in stack compose
  • ✅ Shared network with other services
  • ✅ Cache volume

Network: - Name: audiolab_network - Subnet: 172.25.0.0/16 - Driver: bridge

Security: - ✅ .env.example template - ✅ Secrets externalized - ✅ No hardcoded passwords

🎯 Phase 3: Management Scripts (PROMPT 3)

Location: scripts/

Created Scripts:

stack-manager.ps1 (PowerShell)

.\stack-manager.ps1 -Action start
.\stack-manager.ps1 -Action status
.\stack-manager.ps1 -Action logs -Service postgres
.\stack-manager.ps1 -Action backup

Features: - Start/stop/restart services - Status dashboard with ports - Live log tailing - Volume backup

stack-manager.sh (Bash)

Cross-platform equivalent for Linux/Mac

backup-all.ps1

Comprehensive backup: - Docker volumes - Configuration files - PostgreSQL database dump

ci-build.yml

GitHub Actions workflow: - Automatic docs build on commit - Hierarchy scanning - Static site generation - GitHub Pages deployment

🔄 IMPROVEMENTS OVER LEGACY

Security

  • ❌ Legacy: Hardcoded passwords
  • ✅ New: .env file with secrets externalized

Consistency

  • ❌ Legacy: Inconsistent database names (audiolab vs audiolab_main)

  • ✅ New: Standardized to audiolab_main

  • ❌ Legacy: FossFLOW image name inconsistency (stansmith vs stnsmith)

  • ✅ New: Fixed to stnsmith/fossflow:latest

Automation

  • ❌ Legacy: Manual hierarchy navigation
  • ✅ New: Automatic scanning and nav generation

Documentation

  • ❌ Legacy: Scattered across multiple files
  • ✅ New: Comprehensive READMEs with examples

CI/CD

  • ❌ Legacy: No automated builds
  • ✅ New: GitHub Actions workflow

Backup

  • ❌ Legacy: Only Docker volumes
  • ✅ New: Volumes + configs + database dumps

🚀 QUICK START

1. Configure Secrets

cd 03_06_07_services_stack/
cp .env.example .env
# Edit .env and set POSTGRES_PASSWORD

2. Start Services

# Windows
.\scripts\stack-manager.ps1 -Action start

# Linux/Mac
./scripts/stack-manager.sh start

3. Access

🎯 NEXT STEPS

Optional: Evaluate Legacy Services

From legacy that were NOT migrated (awaiting evaluation):

  1. Nexus Repository (nexus_docker-compose.yml)
  2. Status: Not migrated
  3. Decision: Evaluate if needed or use GitHub Packages

  4. Location if kept: 03_06_08_artifact_management/

  5. Typesense Search (typesense_docker-compose.yml)

  6. Status: Not migrated
  7. Decision: Test if MkDocs search is sufficient

  8. Alternative: Algolia DocSearch (free)

  9. PgAdmin (postgres_docker-compose.yml)

  10. Status: Available in legacy compose
  11. Decision: Dev-only tool, deploy manually if needed

Production Hardening

  • Pin Docker image versions with SHA256
  • Add Traefik/Nginx reverse proxy
  • Configure SSL/TLS
  • Add monitoring (Prometheus + Grafana)
  • Set up log aggregation (Loki)

✅ VALIDATION CHECKLIST

  • MkDocs service builds successfully
  • PostgreSQL schema initializes
  • FossFLOW integration configured
  • Scripts executable (chmod +x)
  • .env.example templates created
  • READMEs complete
  • Network configured (audiolab_network)
  • Volume mounts correct
  • Backup scripts functional
  • CI/CD workflow ready
