v0.5.0: Production Deployment System

[KeshavVarad]

🚀 v0.5.0: Production Deployment System

Complete deployment tooling for Docker and cloud platforms with health checks, graceful shutdown, and one-click deployment commands.

---

What's New

🏥 Health Check System

Production-ready health monitoring with Kubernetes-compatible endpoints:

• Liveness checks: Is the app running?
• Readiness checks: Is the app ready to serve traffic?
• Custom check registration with status tracking
• Automatic duration measurement

from nextmcp.deployment import HealthCheck

health = HealthCheck()

def check_database():
    return db.is_connected()

health.add_readiness_check("database", check_database)

🛑 Graceful Shutdown

Clean application termination with resource cleanup:

• SIGTERM/SIGINT signal handling
• Configurable shutdown timeout
• Async and sync cleanup handlers
• Prevents data loss during deployment

from nextmcp.deployment import GracefulShutdown

shutdown = GracefulShutdown(timeout=30.0)
shutdown.add_cleanup_handler(close_database)
shutdown.register()

🐳 Docker Templates

Optimized Docker deployment with one command:

• Multi-stage Dockerfile (<100MB images)
• docker-compose.yml with optional PostgreSQL/Redis
• Non-root user security
• Built-in health checks

mcp init --docker --with-database

🚢 One-Command Deployment

Deploy to multiple platforms instantly:

• Docker: Local development
• Railway: Automated deployment
• Render: Git-based deployment
• Fly.io: Edge deployment

mcp deploy --platform docker
mcp deploy --platform railway

🎯 Enhanced CLI

# Generate Docker files
mcp init --docker --with-database --with-redis

# Deploy with auto-detection
mcp deploy

# Deploy to specific platform
mcp deploy --platform fly

🎬 Demo

Quick Start

# Create new project
mcp init my-app

# Generate Docker files
cd my-app
mcp init --docker --with-database

# Deploy locally
mcp deploy --platform docker

# View health
curl http://localhost:8000/health

Example Output

{
  "status": "healthy",
  "uptime_seconds": 123.45,
  "checks": {
    "database": {
      "status": "healthy",
      "message": "Database connection is healthy",
      "duration_ms": 2.34
    }
  }
}
