Deployment Steps

Step 1: Pre-Deployment Checks

# Verify system requirements
./scripts/check_system_requirements.sh

# Check port availability
./scripts/check_port_availability.sh

# Validate Docker installation
docker --version
docker-compose --version

Step 2: Database Initialization

# Initialize PostgreSQL database
docker-compose exec postgres psql -U piper_user -d piper_morgan_staging -f /docker-entrypoint-initdb.d/init.sql

# Verify database connection
docker-compose exec app python -c "from services.database import get_db; print('Database connection successful')"

Step 3: Service Deployment

# Start core services
docker-compose up -d postgres redis chromadb

# Wait for services to be ready
./scripts/wait_for_services.sh

# Deploy application
docker-compose up -d app

# Deploy monitoring stack
docker-compose up -d prometheus grafana

Step 4: Health Verification

# Run comprehensive health checks
./scripts/verify_staging_deployment.sh

# Expected output: 14/14 tests passing

Troubleshooting

Common Issues

Service Won’t Start

# Check service logs
docker-compose logs [service_name]

# Verify port conflicts
netstat -tulpn | grep :8001

# Check resource usage
docker stats

Database Connection Issues

# Verify PostgreSQL is running
docker-compose exec postgres pg_isready

# Check connection parameters
docker-compose exec app python -c "import os; print(os.getenv('DATABASE_URL'))"

Performance Issues

# Check MCP connection pool status
curl http://localhost:8001/health/mcp

# Monitor resource usage
docker stats --no-stream

Recovery Procedures

Service Restart

# Restart specific service
docker-compose restart [service_name]

# Restart all services
docker-compose restart

Database Recovery

# Backup current data
docker-compose exec postgres pg_dump -U piper_user piper_morgan_staging > backup.sql

# Restore from backup
docker-compose exec -T postgres psql -U piper_user -d piper_morgan_staging < backup.sql

Rollback Procedures

Automatic Rollback

The staging environment includes automatic rollback capabilities:

# Trigger rollback to previous version
./scripts/rollback_staging.sh

# Verify rollback success
./scripts/verify_staging_deployment.sh

Manual Rollback

# Stop current deployment
docker-compose down

# Restore previous version
git checkout HEAD~1
docker-compose up -d

# Verify rollback
./scripts/verify_staging_deployment.sh

Security Considerations

Network Security

Internal Communication: Services communicate over Docker network
External Access: Only Nginx proxy exposed to host
Port Binding: Limited to localhost for development

Data Security

Database: No external access, internal Docker network only
Credentials: Environment variables, not hardcoded
Backups: Automated daily backups with encryption

Performance Tuning

MCP Connection Pooling

# Monitor connection pool status
curl http://localhost:8001/health/mcp

# Expected metrics:
# - Active connections: 5-10
# - Pool size: 20
# - Connection wait time: <10ms

Database Optimization

# Check query performance
docker-compose exec postgres psql -U piper_user -d piper_morgan_staging -c "SELECT * FROM pg_stat_statements ORDER BY mean_time DESC LIMIT 10;"

Maintenance

Regular Tasks

Daily: Health check verification
Weekly: Performance metrics review
Monthly: Security updates and dependency upgrades

Backup Strategy

# Automated daily backup
0 2 * * * /scripts/backup_staging.sh

# Manual backup
./scripts/backup_staging.sh

# Restore from backup
./scripts/restore_staging.sh backup_2025-08-11.sql
