# Docker Compose → Kubernetes Architecture Redesign

## Overview

This document outlines the aggressive redesign of MotoVaultPro's Docker Compose architecture to closely replicate a Kubernetes deployment pattern. **Breaking changes are acceptable** as this is a pre-production application. The goal is to completely replace the current architecture with a production-ready K8s-equivalent setup in 2-3 days, eliminating all development shortcuts and implementing true production constraints.

**SCOPE**: ETL services have been completely removed from the architecture. This migration covers the 11 remaining core services with a focus on security, observability, and K8s compatibility over backward compatibility.

## Current Architecture Analysis

### Core Services for Migration (11 containers)

**MVP Platform Services (Microservices)**
- `mvp-platform-landing` - Marketing/landing page (nginx)
- `mvp-platform-tenants` - Multi-tenant management API (FastAPI)
- `mvp-platform-vehicles-api` - Vehicle data API (FastAPI)
- `mvp-platform-vehicles-db` - Vehicle data storage (PostgreSQL)
- `mvp-platform-vehicles-redis` - Vehicle data cache (Redis)

**Application Services (Modular Monolith)**
- `admin-backend` - Application API with feature capsules (Node.js)
- `admin-frontend` - React SPA (nginx)
- `admin-postgres` - Application database (PostgreSQL)
- `admin-redis` - Application cache (Redis)
- `admin-minio` - Object storage (MinIO)

**Infrastructure**
- `platform-postgres` - Platform services database
- `platform-redis` - Platform services cache
- `nginx-proxy` - **TO BE COMPLETELY REMOVED** (replaced by Traefik)

### Current Limitations (TO BE BROKEN)

1. **Single Network**: All services on default network - **BREAKING: Move to isolated networks**
2. **Manual Routing**: nginx configuration requires manual updates - **BREAKING: Complete removal**
3. **Excessive Port Exposure**: 10+ services expose ports directly - **BREAKING: Remove all except Traefik**
4. **Environment Variable Configuration**: 35+ env vars scattered across services - **BREAKING: Mandatory file-based config**
5. **Development Shortcuts**: Debug modes, open CORS, no authentication - **BREAKING: Production-only mode**
6. **No Resource Limits**: Services can consume unlimited resources - **BREAKING: Enforce limits on all services**

## Target Kubernetes-like Architecture

### Network Segmentation (Aggressive Isolation)

```yaml
networks:
  frontend:
    driver: bridge
    internal: false  # Only for Traefik public access
    labels:
      - "com.motovaultpro.network=frontend"
      - "com.motovaultpro.purpose=public-traffic-only"

  backend:
    driver: bridge
    internal: true   # Complete isolation from host
    labels:
      - "com.motovaultpro.network=backend"
      - "com.motovaultpro.purpose=api-services"

  database:
    driver: bridge
    internal: true   # Application data isolation
    labels:
      - "com.motovaultpro.network=database"
      - "com.motovaultpro.purpose=app-data-layer"

  platform:
    driver: bridge
    internal: true   # Platform microservices isolation
    labels:
      - "com.motovaultpro.network=platform"
      - "com.motovaultpro.purpose=platform-services"
```

**BREAKING CHANGE**: No `egress` network. Services requiring external API access (Auth0, Google Maps, VPIC) will connect through the `backend` network with Traefik handling external routing. This forces all external communication through the ingress controller, matching Kubernetes egress gateway patterns.

### Service Placement Strategy (Aggressive Isolation)

| Service | Networks | Purpose | K8s Equivalent |
|---------|----------|---------|----------------|
| `traefik` | `frontend`, `backend` | **ONLY** public routing + API access | LoadBalancer + IngressController |
| `admin-frontend`, `mvp-platform-landing` | `frontend` | Public web applications | Ingress frontends |
| `admin-backend` | `backend`, `database`, `platform` | Application API with cross-service access | ClusterIP with multiple network attachment |
| `mvp-platform-tenants`, `mvp-platform-vehicles-api` | `backend`, `platform` | Platform APIs + data access | ClusterIP (platform namespace) |
| `admin-postgres`, `admin-redis`, `admin-minio` | `database` | Application data isolation | StatefulSets with PVCs |
| `platform-postgres`, `platform-redis`, `mvp-platform-vehicles-db`, `mvp-platform-vehicles-redis` | `platform` | Platform data isolation | StatefulSets with PVCs |

**BREAKING CHANGES**:
- **No external network access** for individual services
- **No host port exposure** except Traefik (80, 443, 8080)
- **Mandatory network isolation** - services cannot access unintended networks
- **No development bypasses** - all traffic through Traefik

**Service Communication Matrix (Restricted)**
```
# Internal service communication (via backend network)
admin-backend → mvp-platform-vehicles-api:8000 (authenticated API calls)
admin-backend → mvp-platform-tenants:8000 (authenticated API calls)

# Data layer access (isolated networks)
admin-backend → admin-postgres:5432, admin-redis:6379, admin-minio:9000
mvp-platform-vehicles-api → mvp-platform-vehicles-db:5432, mvp-platform-vehicles-redis:6379
mvp-platform-tenants → platform-postgres:5432, platform-redis:6379

# External integrations (BREAKING: via Traefik proxy only)
admin-backend → External APIs (Auth0, Google Maps, VPIC) via Traefik middleware
Platform services → External APIs via Traefik middleware (no direct access)
```

**BREAKING CHANGE**: All external API calls must be proxied through Traefik middleware. No direct external network access for any service.

## Traefik Configuration

### Core Traefik Setup

- New directories `config/traefik/` and `secrets/traefik/` will store production-bound configuration and certificates. These folders are justified as they mirror their eventual Kubernetes ConfigMap/Secret counterparts and replace the legacy nginx configuration.

```yaml
traefik:
  image: traefik:v3.0
  container_name: traefik
  networks:
    - frontend
    - backend
  ports:
    - "80:80"
    - "443:443"
    - "8080:8080"  # Dashboard
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock:ro
    - ./config/traefik/traefik.yml:/etc/traefik/traefik.yml:ro
    - ./config/traefik/middleware.yml:/etc/traefik/middleware.yml:ro
    - ./secrets/traefik/certs:/certs:ro
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.dashboard.rule=Host(`traefik.motovaultpro.local`)"
    - "traefik.http.routers.dashboard.tls=true"
    - "traefik.http.routers.dashboard.middlewares=dashboard-allowlist@docker"
    - "traefik.http.middlewares.dashboard-allowlist.ipwhitelist.sourcerange=10.0.0.0/8,172.16.0.0/12,192.168.0.0/16"
```

### Service Discovery Labels

**Admin Frontend**
```yaml
admin-frontend:
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.admin-app.rule=Host(`admin.motovaultpro.com`)"
    - "traefik.http.routers.admin-app.tls=true"
    - "traefik.http.routers.admin-app.middlewares=secure-headers@file"
    - "traefik.http.services.admin-app.loadbalancer.server.port=3000"
    - "traefik.http.services.admin-app.loadbalancer.healthcheck.path=/"
```

**Admin Backend**
```yaml
admin-backend:
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.admin-api.rule=Host(`admin.motovaultpro.com`) && PathPrefix(`/api`)"
    - "traefik.http.routers.admin-api.tls=true"
    - "traefik.http.routers.admin-api.middlewares=api-auth@file,cors@file"
    - "traefik.http.services.admin-api.loadbalancer.server.port=3001"
    - "traefik.http.services.admin-api.loadbalancer.healthcheck.path=/health"
```

**Platform Landing**
```yaml
mvp-platform-landing:
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.landing.rule=Host(`motovaultpro.com`)"
    - "traefik.http.routers.landing.tls=true"
    - "traefik.http.routers.landing.middlewares=secure-headers@file"
    - "traefik.http.services.landing.loadbalancer.server.port=3000"
```

### Middleware Configuration

```yaml
# config/traefik/middleware.yml
http:
  middlewares:
    secure-headers:
      headers:
        accessControlAllowMethods:
          - GET

          - PUT
          - POST
          - DELETE
        accessControlAllowOriginList:
          - "https://admin.motovaultpro.com"
          - "https://motovaultpro.com"
        accessControlMaxAge: 100

          - "172.16.0.0/12"
          - "192.168.0.0/16"
```

## Enhanced Health Checks

### Standardized Health Check Pattern

All services will implement:

1. **Startup Probe** - Service initialization
2. **Readiness Probe** - Service ready to accept traffic
3. **Liveness Probe** - Service health monitoring

```yaml
# Example: admin-backend
healthcheck:
  test: ["CMD", "node", "-e", "
    const http = require('http');
    const options = {
      hostname: 'localhost',
      port: 3001,
      path: '/health/ready',
      timeout: 2000
    };
    const req = http.request(options, (res) => {
      process.exit(res.statusCode === 200 ? 0 : 1);
    });
    req.on('error', () => process.exit(1));
    req.end();
  "]
  interval: 15s
  timeout: 5s
  retries: 3
  start_period: 45s
```

### Health Endpoint Standards

All services must expose:
- `/health` - Basic health check
- `/health/ready` - Readiness probe
- `/health/live` - Liveness probe

## Configuration Management

### Configuration & Secret Management (Compose-compatible)

- Application and platform settings will live in versioned files under `config/app/` and `config/platform/`, mounted read-only into the containers (`volumes:`). This mirrors ConfigMaps without relying on Docker Swarm-only `configs`.
- Secrets (Auth0, database, API keys) will be stored as individual files beneath `secrets/app/` and `secrets/platform/`, mounted as read-only volumes. At runtime the containers will read from `/run/secrets/*`, matching the eventual Kubernetes Secret mount pattern.
- Committed templates: `.example` files now reside in `config/app/production.yml.example`, `config/platform/production.yml.example`, and `secrets/**/.example` to document required keys while keeping live credentials out of Git. The real files stay untracked via `.gitignore`.
- Runtime loader: extend `backend/src/core/config/environment.ts` (and equivalent FastAPI settings) to hydrate configuration by reading `CONFIG_PATH` YAML and `SECRETS_DIR` file values before falling back to `process.env`. This ensures parity between Docker Compose mounts and future Kubernetes ConfigMap/Secret projections.

#### Configuration Migration Strategy

**Current Environment Variables (45 total) to File Mapping:**

**Application Secrets** (`secrets/app/`):
```
auth0-client-secret.txt        # AUTH0_CLIENT_SECRET
postgres-password.txt          # DB_PASSWORD
minio-access-key.txt          # MINIO_ACCESS_KEY
minio-secret-key.txt          # MINIO_SECRET_KEY
platform-vehicles-api-key.txt # PLATFORM_VEHICLES_API_KEY
google-maps-api-key.txt       # GOOGLE_MAPS_API_KEY
```

**Platform Secrets** (`secrets/platform/`):
```
platform-db-password.txt      # PLATFORM_DB_PASSWORD
vehicles-db-password.txt      # POSTGRES_PASSWORD (vehicles)
```

**Network attachments for outbound-enabled services:**
```yaml
mvp-platform-vehicles-api:
  networks:
    - backend
    - platform
    - egress

mvp-platform-tenants:
  networks:
    - backend
    - platform
    - egress
```

**Application Configuration** (`config/app/production.yml`):
```yaml
server:
  port: 3001
  tenant_id: admin

database:
  host: admin-postgres
  port: 5432
  name: motovaultpro
  user: postgres

redis:
  host: admin-redis
  port: 6379

minio:
  endpoint: admin-minio
  port: 9000
  bucket: motovaultpro

auth0:
  domain: motovaultpro.us.auth0.com
  audience: https://api.motovaultpro.com

platform:
  vehicles_api_url: http://mvp-platform-vehicles-api:8000
  tenants_api_url: http://mvp-platform-tenants:8000

external:
  vpic_api_url: https://vpic.nhtsa.dot.gov/api/vehicles
```

**Compose Example:**
```yaml
  admin-backend:
    volumes:
      - ./config/app/production.yml:/app/config/production.yml:ro
      - ./secrets/app/auth0-client-secret.txt:/run/secrets/auth0-client-secret:ro
      - ./secrets/app/postgres-password.txt:/run/secrets/postgres-password:ro
      - ./secrets/app/minio-access-key.txt:/run/secrets/minio-access-key:ro
      - ./secrets/app/minio-secret-key.txt:/run/secrets/minio-secret-key:ro
      - ./secrets/app/platform-vehicles-api-key.txt:/run/secrets/platform-vehicles-api-key:ro
      - ./secrets/app/google-maps-api-key.txt:/run/secrets/google-maps-api-key:ro
    environment:
      - NODE_ENV=production
      - CONFIG_PATH=/app/config/production.yml
      - SECRETS_DIR=/run/secrets
    networks:
      - backend
      - database
      - platform
      - egress
```

## Resource Management

### Resource Allocation Strategy

**Tier 1: Critical Services**
```yaml
  admin-backend:
    mem_limit: 2g
    cpus: 2.0
```

**Tier 2: Supporting Services**
```yaml
  admin-frontend:
    mem_limit: 1g
    cpus: 1.0
```

**Tier 3: Infrastructure Services**
```yaml
  traefik:
    mem_limit: 512m
    cpus: 0.5
```

### Service Tiers

| Tier | Services | Resource Profile | Priority |
|------|----------|------------------|----------|
| 1 | admin-backend, mvp-platform-vehicles-api, admin-postgres | High | Critical |
| 2 | admin-frontend, mvp-platform-tenants, mvp-platform-landing | Medium | Important |
| 3 | traefik, redis services, storage services | Low | Supporting |

### Development Port Exposure Policy

**Exposed Ports for Development Debugging:**
```yaml
# Database Access (development debugging)
- 5432:5432    # admin-postgres (application DB access)
- 5433:5432    # mvp-platform-vehicles-db (platform DB access)
- 5434:5432    # platform-postgres (platform services DB access)

# Cache Access (development debugging)
- 6379:6379    # admin-redis
- 6380:6379    # mvp-platform-vehicles-redis
- 6381:6379    # platform-redis

# Storage Access (development/admin)
- 9000:9000    # admin-minio API
- 9001:9001    # admin-minio console

# Traefik Dashboard (development monitoring)
- 8080:8080    # traefik dashboard
```

**Internal-Only Services (no port exposure):**
- All HTTP application services (routed through Traefik)
- Platform APIs (accessible via application backend only)

**Mobile Testing Considerations:**
- Self-signed certificates require device-specific trust configuration
- Development URLs must be accessible from mobile devices on same network
- Certificate CN must match both `motovaultpro.com` and `admin.motovaultpro.com`

## Migration Implementation Plan (Aggressive Approach)

### **BREAKING CHANGE STRATEGY**: Complete Architecture Replacement (2-3 Days)

**Objective**: Replace entire Docker Compose architecture with K8s-equivalent setup in a single migration event. No backward compatibility, no gradual transition, no service uptime requirements.

### **Day 1: Complete Infrastructure Replacement**

**Breaking Changes Implemented:**
1. **Remove nginx-proxy completely** - no parallel operation
2. **Implement Traefik with full production configuration**
3. **Break all current networking** - implement 4-network isolation from scratch
4. **Remove ALL development port exposure** (10+ ports → 3 ports)
5. **Break environment variable patterns** - implement mandatory file-based configuration

**Tasks:**
```bash
# 1. Backup current state
cp docker-compose.yml docker-compose.old.yml
docker compose down

# 2. Create configuration structure
mkdir -p config/app config/platform secrets/app secrets/platform

# 3. Generate production-ready certificates
make generate-certs  # Multi-domain with mobile compatibility

# 4. Implement new docker-compose.yml with:
#    - 4 isolated networks
#    - Traefik service with full middleware
#    - No port exposure except Traefik (80, 443, 8080)
#    - File-based configuration for all services
#    - Resource limits on all services

# 5. Update all service configurations to use file-based config
#    - Remove all environment variables from compose
#    - Implement CONFIG_PATH and SECRETS_DIR loaders
```

**Expected Failures**: Services will fail to start until configuration files are properly implemented.

### **Day 2: Service Reconfiguration & Authentication**

**Breaking Changes Implemented:**
1. **Mandatory service-to-service authentication** - remove all debug/open access
2. **Implement standardized health endpoints** - break existing health check patterns
3. **Enforce resource limits** - services may fail if exceeding limits
4. **Remove CORS development shortcuts** - production-only security

**Tasks:**
```bash
# 1. Implement /health, /health/ready, /health/live on all HTTP services
# 2. Update Dockerfiles and service code for new health endpoints
# 3. Configure Traefik labels for all services
# 4. Implement service authentication:
#    - API keys for platform service access
#    - Remove debug modes and localhost CORS
#    - Implement production security headers
# 5. Add resource limits to all services
# 6. Test new architecture end-to-end
```

**Expected Issues**: Authentication failures, CORS errors, resource limit violations.

### **Day 3: Validation & Documentation Update**

**Tasks:**
1. **Complete testing** of new architecture
2. **Update all documentation** to reflect new constraints
3. **Update Makefile** with breaking changes to commands
4. **Validate mobile access** with new certificate and routing
5. **Performance validation** (baseline not required - new architecture is target)

### **BREAKING CHANGES SUMMARY**

#### **Network Access**
- **OLD**: All services on default network with host access
- **NEW**: 4 isolated networks, no host access except Traefik

#### **Port Exposure**
- **OLD**: 10+ ports exposed (databases, APIs, storage)
- **NEW**: Only 3 ports (80, 443, 8080) - everything through Traefik

#### **Configuration**
- **OLD**: 35+ environment variables scattered across services
- **NEW**: Mandatory file-based configuration with no env fallbacks

#### **Development Access**
- **OLD**: Direct database/service access via exposed ports
- **NEW**: Access only via `docker exec` or Traefik routing

#### **Security**
- **OLD**: Debug modes, open CORS, no authentication
- **NEW**: Production security only, mandatory authentication

#### **Resource Management**
- **OLD**: Unlimited resource consumption
- **NEW**: Enforced limits on all services

### **Risk Mitigation**

1. **Document current working state** before migration (Day 0)
2. **Keep docker-compose.old.yml** for reference
3. **Backup all volumes** before starting
4. **Expect multiple restart cycles** during configuration
5. **Plan for debugging time** - new constraints will reveal issues

### **Success Criteria (Non-Negotiable)**
- ✅ All 11 services operational through Traefik only
- ✅ Zero host port exposure except Traefik
- ✅ All configuration file-based
- ✅ Service-to-service authentication working
- ✅ Mobile and desktop HTTPS access functional
- ✅ Resource limits enforced and services stable

## Development Workflow Enhancements (BREAKING CHANGES)

    addRoutersLabels: true
```

### Logging Strategy

**Centralized Logging**
- All services log to stdout/stderr
- Traefik access logs
- Service health check logs
- Application performance logs

**Log Levels**
- `ERROR`: Critical issues requiring attention
- `WARN`: Potential issues or degraded performance
- `INFO`: Normal operational messages
- `DEBUG`: Detailed diagnostic information (dev only)

### Health Monitoring

**Service Health Dashboard**
- Real-time service status via Traefik dashboard
- Historical health trends (Phase 4 enhancement)
- Network connectivity validation
- Mobile accessibility monitoring

**Critical Monitoring Points:**
1. **Service Discovery**: All services registered with Traefik
2. **Network Isolation**: Services only accessible via designated networks
3. **SSL Certificate Status**: Valid certificates for all domains
4. **Mobile Compatibility**: Certificate trust and network accessibility
5. **Database Connectivity**: Cross-network database access patterns
6. **Platform API Authentication**: Service-to-service authentication working

**Development Health Checks:**
```bash
# Quick health validation
make health-check-all
make service-discovery
make network-inspect

# Mobile testing validation
make mobile-setup
curl -k https://admin.motovaultpro.com/health  # From mobile device IP
```

**Service Health Dashboard**
- Real-time service status
- Historical health trends
- Alert notifications
- Performance metrics

## Security Enhancements

### Network Security

**Network Isolation**
- Frontend network: Public-facing services only
- Backend network: API services with restricted access
- Database network: Data services with no external access
- Platform network: Microservices internal communication

**Access Control**
- Traefik middleware for authentication
- Service-to-service authentication
- Network-level access restrictions
- SSL/TLS encryption for all traffic

### Secret Management

**Secrets Rotation**
- Database passwords
- API keys
- SSL certificates
- Auth0 client secrets

**Access Policies**
- Least privilege principle
- Service-specific secret access
- Audit logging for secret access
- Encrypted secret storage

## Testing Strategy

### Automated Testing

**Integration Tests**
- Service discovery validation
- Health check verification
- SSL certificate testing
- Load balancing functionality

**Performance Tests**
- Service response times
- Network latency measurement
- Resource utilization monitoring
- Concurrent user simulation

**Security Tests**
- Network isolation verification
- Authentication middleware testing
- SSL/TLS configuration validation
- Secret management verification

### Manual Testing Procedures

**Development Workflow**
1. Service startup validation
2. Route accessibility testing
3. Mobile/desktop compatibility
4. Feature functionality verification
5. Performance benchmarking

**Deployment Validation**
1. Service discovery verification
2. Health check validation
3. SSL certificate functionality
4. Load balancing behavior
5. Failover testing

## Migration Rollback Plan

### Rollback Triggers

- Service discovery failures
- Performance degradation > 20%
- SSL certificate issues
- Health check failures
- Mobile/desktop compatibility issues

### Rollback Procedure

1. **Immediate**: Switch DNS to backup nginx configuration
2. **Quick**: Restore docker-compose.yml.backup
3. **Complete**: Revert all configuration changes
4. **Verify**: Run full test suite
5. **Monitor**: Ensure service stability

### Backup Strategy

**Critical Data Backup:**
- Backup platform services PostgreSQL database:
  ```bash
  docker compose exec platform-postgres pg_dump -U platform_user platform > platform_backup_$(date +%Y%m%d_%H%M%S).sql
  ```

**Note:** All other services are stateless or use development data that can be recreated. Application database, Redis, and MinIO contain only development data.

## Success Metrics

### Performance Metrics

- **Service Startup Time**: < 30 seconds for all services
- **Request Response Time**: < 500ms for API calls
- **Health Check Response**: < 2 seconds

## Conclusion

This aggressive redesign completely replaces the Docker Compose architecture with a production-ready K8s-equivalent setup in 2-3 days. **Breaking changes are the strategy** - eliminating all development shortcuts and implementing true production constraints from day one.

### **Key Transformation**
- **11 services** migrated from single-network to 4-network isolation
- **10+ exposed ports** reduced to 3 (Traefik only)
- **35+ environment variables** replaced with mandatory file-based configuration
- **All development bypasses removed** - production security enforced
- **Direct service access eliminated** - all traffic through Traefik

### **Benefits of Aggressive Approach**
1. **Faster Implementation**: 2-3 days vs 4 weeks of gradual migration
2. **Authentic K8s Simulation**: True production constraints from start
3. **No Legacy Debt**: Clean architecture without compatibility layers
4. **Better Security**: Production-only mode eliminates development vulnerabilities
5. **Simplified Testing**: Single target architecture instead of multiple transition states

### **Post-Migration State**
The new architecture provides an exact Docker Compose equivalent of Kubernetes deployment patterns. All services operate under production constraints with proper isolation, authentication, and resource management. This setup can be directly translated to Kubernetes manifests with minimal changes.

**Development teams gain production-like experience while maintaining local development efficiency through container-based workflows and Traefik-based service discovery.**
