# šŸ³ Pharmacy Docker Orchestration Specialist

## Operational Ground Rules
- Frontend is Dockerized with HMR. Control via docker compose, not npm restart.
  - Start: `docker compose up -d frontend`
  - Logs: `docker compose logs -f frontend`
  - Restart: `docker compose restart frontend`
- Use Tailscale IPs for cross-device access:
  - Server: 100.120.219.68
  - API (Backend): http://100.120.219.68:3001
  - Frontend: http://100.120.219.68:3000
  - Capcom6: http://100.126.232.47:8080
- Volumes policy: use named volumes for state; bind mounts only for dev HMR.
- Role-specific:
  - Verify volumes usage: `docker volume ls`, inspect with `docker volume inspect <name>`
  - Avoid writable config bind mounts; prefer COPY or read-only mounts.
  - Helpful: `docker compose config`, `docker compose ps`
- See: [docker-compose.yml](docker-compose.yml:1), [CLAUDE.md](CLAUDE.md:1)

```

## Docker Compose Management

### Current Docker Compose Structure
```yaml
name: pharmacy-scheduling

services:
  # Frontend Development Server
  frontend:
    container_name: pharm-frontend
    build:
      context: ./frontend
      dockerfile: Dockerfile.dev
    restart: unless-stopped
    ports:
      - "3000:3000"
    volumes:
      # Hot reload volumes
      - ./frontend/src:/app/src
      - ./frontend/public:/app/public
      - /app/node_modules  # Exclude node_modules
    environment:
      - VITE_BACKEND_URL=http://localhost:3001
      - VITE_SOCKET_URL=http://localhost:3001
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:3000"]
      interval: 30s
      timeout: 10s
      retries: 3
    depends_on:
      backend:
        condition: service_healthy

  # PostgreSQL Database
  db:
    container_name: pharm-db
    image: postgres:15-alpine
    restart: unless-stopped
    volumes:
      # Schema initialization
      - ./backend/db/init:/docker-entrypoint-initdb.d:ro
      # Persistent configuration
      - db-config:/etc/postgresql-custom
    environment:
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
      POSTGRES_DB: ${POSTGRES_DB}
      JWT_SECRET: ${JWT_SECRET}
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "postgres", "-h", "localhost"]
      interval: 5s
      timeout: 5s
      retries: 10
```

### Service Dependencies and Startup Order
1. **Database** (db) - Must start first, provides foundation for all services
2. **Authentication & API** (auth, rest) - Depend on healthy database
3. **Backend** (Express) - Requires db service
4. **Edge Functions** (functions) - Can start independently
5. **Frontend** (frontend) - Waits for healthy API gateway
6. **Workflow Platform** (n8n) - Requires healthy database
7. **Connection Pooler** (supavisor) - Optional, depends on database

## Container Management Operations

### Essential Docker Commands
```bash
# Service lifecycle management
docker compose up -d                    # Start all services
docker compose ps                       # Check service status
docker compose logs <service> --tail=20 # View service logs
docker compose restart <service>        # Restart specific service
docker compose down                     # Stop all services

# Health monitoring
docker compose ps --format table        # Formatted service status
docker stats --no-stream               # Resource usage snapshot
docker compose top                     # Running processes in containers

# Development workflow
docker compose up -d frontend          # Start frontend only
docker compose logs frontend --follow  # Follow frontend logs
docker compose exec db psql -U postgres # Access database directly
```

### Service-Specific Operations
```bash
# Database operations
docker compose exec db pg_isready -U postgres
docker compose exec db psql -U postgres -c "SELECT version()"
docker compose logs db | grep -i error

# Frontend development
docker compose restart frontend         # Restart after config changes
docker compose exec frontend npm run build  # Build production assets
docker compose logs frontend --follow   # Monitor hot reload

# API Gateway management
docker compose logs backend --tail=20   # Monitor API requests
docker compose restart backend          # Restart after config changes

# Workflow automation
docker compose logs n8n --tail=20       # Monitor workflow executions
curl -u admin:admin123 http://localhost:5678/healthz  # Health check
```

## Environment Configuration Management

### Environment Variable Organization
```bash
# Core Backend Configuration
JWT_SECRET=change_me

# Database Configuration
POSTGRES_PASSWORD=your_secure_postgres_password
POSTGRES_DB=pharmacy
POSTGRES_HOST=db
POSTGRES_PORT=5432

# External Services
CAPCOM6_PASSWORD=your_password
OPENROUTER_API_KEY=your_openrouter_api_key

# Application URLs
SITE_URL=http://localhost:3000
API_EXTERNAL_URL=http://localhost:3001
```

### Configuration Security
```bash
# Validate environment configuration
source .env && echo "Environment loaded successfully"

# Check for missing variables
docker compose config | grep -i "warning\|error"

# Verify service environment
docker compose exec frontend env | grep VITE_
docker compose exec db env | grep POSTGRES_
```

## Volume and Data Management

### Named Volumes
```yaml
volumes:
  db-config:
    # PostgreSQL configuration persistence
    driver: local
  
  n8n_data:
    # n8n workflow and execution data
    driver: local
```

### Volume Operations
```bash
# List all volumes
docker volume ls | grep pharmacy-scheduling

# Inspect volume contents
docker volume inspect pharmacy-scheduling_db-config

# Backup volume data
docker run --rm -v pharmacy-scheduling_db-config:/data -v $(pwd):/backup alpine tar czf /backup/db-config-backup.tar.gz -C /data .

# Restore volume data
docker run --rm -v pharmacy-scheduling_db-config:/data -v $(pwd):/backup alpine tar xzf /backup/db-config-backup.tar.gz -C /data
```

### Database Data Persistence
```bash
# Create database backup
docker compose exec db pg_dump -U postgres postgres > pharmacy_backup_$(date +%Y%m%d_%H%M%S).sql

# Restore database from backup
docker compose exec -T db psql -U postgres postgres < pharmacy_backup.sql

# Monitor database size
docker compose exec db du -sh /var/lib/postgresql/data
```

## Development Environment Optimization

### Hot Reload Configuration
```yaml
# Frontend hot reload setup
frontend:
  volumes:
    # Source code mapping for live updates
    - ./frontend/src:/app/src
    - ./frontend/public:/app/public
    - ./frontend/index.html:/app/index.html
    - ./frontend/package.json:/app/package.json
    - ./frontend/vite.config.ts:/app/vite.config.ts
    - ./frontend/tailwind.config.ts:/app/tailwind.config.ts
    # Exclude node_modules to prevent conflicts
    - /app/node_modules
  environment:
    # Enable polling for file system events
    - CHOKIDAR_USEPOLLING=true
    - WATCHPACK_POLLING=true
    - NODE_ENV=development
```

### Performance Optimization
```bash
# Monitor resource usage
docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}"

# Optimize memory usage
docker system prune -f  # Remove unused containers/images
docker image prune -f   # Remove dangling images

# Clean up development artifacts
docker compose down --volumes --remove-orphans
docker system prune -a --volumes -f
```

## Network Management

### Internal Service Communication
```yaml
# Service discovery and communication
networks:
  default:
    name: pharmacy-scheduling_default
    
# Internal service URLs (for container-to-container communication)
# backend:3001   - Backend internal
# db:5432        - Database internal
```

### External Network Integration
```bash
# Tailscale network for SMS gateway
# External SMS gateway: 100.126.232.47:8080
# Accessible from within containers via Tailscale

# Test external connectivity
docker compose exec functions curl -f http://100.126.232.47:8080/state

# Monitor network traffic
docker compose exec backend netstat -tuln
```

## Health Monitoring and Troubleshooting

### Comprehensive Health Check
```bash
#!/bin/bash
# pharmacy-health-check.sh

echo "=== Pharmacy System Health Check ==="
echo "Date: $(date)"
echo ""

# Check Docker daemon
echo "Docker Status:"
docker version --format 'Client: {{.Client.Version}}, Server: {{.Server.Version}}'
echo ""

# Check service health
echo "Service Health:"
docker compose ps --format "table {{.Name}}\t{{.Status}}\t{{.Health}}"
echo ""

# Check resource usage
echo "Resource Usage:"
docker stats --no-stream --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"
echo ""

# Test API endpoints
echo "API Connectivity:"
source .env
curl -s -o /dev/null -w "Stores API: %{http_code}\n" \
  -H "Authorization: Bearer $ANON_KEY" \
  -H "apikey: $ANON_KEY" \
  http://localhost:3001/api/health

curl -s -o /dev/null -w "Frontend: %{http_code}\n" http://localhost:3000
curl -s -o /dev/null -w "n8n: %{http_code}\n" http://localhost:5678
echo ""

# Check volume status
echo "Volume Status:"
docker volume ls | grep pharmacy-scheduling
echo ""

echo "=== Health Check Complete ==="
```

### Common Issue Resolution
```bash
# Service won't start - check logs
docker compose logs <service> --tail=50

# Database connection issues
docker compose exec db pg_isready -U postgres
docker compose restart db

# Frontend build issues
docker compose exec frontend npm run build
docker compose restart frontend

# API Gateway issues
docker compose logs backend | grep -i error
docker compose restart backend

# Network connectivity issues
docker network ls | grep pharmacy-scheduling
docker compose down && docker compose up -d
```

## Backup and Recovery Procedures

### Automated Backup Script
```bash
#!/bin/bash
# pharmacy-backup.sh

BACKUP_DIR="./backups/$(date +%Y%m%d_%H%M%S)"
mkdir -p "$BACKUP_DIR"

echo "Creating pharmacy system backup..."

# Database backup
docker compose exec -T db pg_dump -U postgres postgres > "$BACKUP_DIR/database.sql"

# Configuration backup
cp .env "$BACKUP_DIR/env"
cp docker-compose.yml "$BACKUP_DIR/"

# Volume backups
docker run --rm -v pharmacy-scheduling_db-config:/data -v $(pwd)/$BACKUP_DIR:/backup alpine \
  tar czf /backup/db-config.tar.gz -C /data .

docker run --rm -v pharmacy-scheduling_n8n_data:/data -v $(pwd)/$BACKUP_DIR:/backup alpine \
  tar czf /backup/n8n-data.tar.gz -C /data .

# Application code backup
tar czf "$BACKUP_DIR/application-code.tar.gz" \
  --exclude=node_modules \
  --exclude=.git \
  frontend/ backend/ scripts/

echo "Backup completed: $BACKUP_DIR"
```

### Disaster Recovery
```bash
#!/bin/bash
# pharmacy-restore.sh

BACKUP_DIR=$1
if [ -z "$BACKUP_DIR" ]; then
  echo "Usage: $0 <backup_directory>"
  exit 1
fi

echo "Restoring pharmacy system from: $BACKUP_DIR"

# Stop services
docker compose down

# Restore configuration
cp "$BACKUP_DIR/env" .env
cp "$BACKUP_DIR/docker-compose.yml" .

# Restore volumes
docker volume rm pharmacy-scheduling_db-config pharmacy-scheduling_n8n_data
docker volume create pharmacy-scheduling_db-config
docker volume create pharmacy-scheduling_n8n_data

docker run --rm -v pharmacy-scheduling_db-config:/data -v $(pwd)/$BACKUP_DIR:/backup alpine \
  tar xzf /backup/db-config.tar.gz -C /data

docker run --rm -v pharmacy-scheduling_n8n_data:/data -v $(pwd)/$BACKUP_DIR:/backup alpine \
  tar xzf /backup/n8n-data.tar.gz -C /data

# Start services
docker compose up -d

# Wait for database
sleep 30

# Restore database
docker compose exec -T db psql -U postgres postgres < "$BACKUP_DIR/database.sql"

echo "Restore completed"
```

## Security Hardening

### Container Security
```yaml
# Security-focused service configuration
services:
  db:
    security_opt:
      - no-new-privileges:true
    read_only: true
    tmpfs:
      - /tmp
      - /var/run/postgresql
    user: postgres
    
  frontend:
    security_opt:
      - no-new-privileges:true
    read_only: false  # Required for hot reload
```

### Network Security
```bash
# Restrict external access
# Only expose necessary ports to host
ports:
  - "3000:3000"    # Frontend (development only)
  - "8002:8000"    # API Gateway
  - "5678:5678"    # n8n (development only)

# Internal services (no external exposure):
# - Database (access via API Gateway)
# - Authentication service
# - Edge Functions
```

## Performance Monitoring

### Resource Monitoring
```bash
# Monitor container performance
docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}"

# Monitor disk usage
docker system df

# Monitor logs
docker compose logs --tail=100 --follow | grep -E "(ERROR|WARN|FATAL)"
```

### Optimization Recommendations
1. **Database**: Monitor connection counts and query performance
2. **Frontend**: Use multi-stage builds for production
3. **API Gateway**: Configure appropriate rate limiting
4. **Edge Functions**: Monitor execution times and memory usage
5. **Volumes**: Regular cleanup of old data and logs

**Context7 Research Steps:**
1. Use context7 to research the specific error message or issue
2. Look up relevant documentation and troubleshooting guides
3. Verify proper configuration patterns and best practices
4. Only then implement the solution based on researched information

## Emergency Procedures

### Critical Service Failure
```bash
# Emergency restart procedure
docker compose down
docker system prune -f
docker compose up -d

# If database corruption suspected
docker compose down
docker volume rm pharmacy-scheduling_db-config
docker compose up -d
# Restore from backup
```

### Complete System Reset
```bash
# Nuclear option - complete reset
docker compose down --volumes --remove-orphans
docker system prune -a --volumes -f
docker compose up -d
# Restore all data from backups
```

Remember: Container orchestration in pharmacy environments requires careful attention to data persistence, service reliability, and security. Always maintain current backups and test recovery procedures regularly.
