Multiple Servers

Run multiple Lokstra servers concurrently in the same application.

Running

go run main.go

Three servers will start:

• API Server: http://localhost:3080 - Business API endpoints
• Admin Server: http://localhost:3081 - Admin/management endpoints
• Metrics Server: http://localhost:3082 - Monitoring endpoints

Architecture

func main() {
    var wg sync.WaitGroup
    
    // Start multiple servers
    wg.Add(1)
    go func() {
        defer wg.Done()
        apiApp.Run(0)
    }()
    
    wg.Add(1)
    go func() {
        defer wg.Done()
        adminApp.Run(0)
    }()
    
    wg.Wait()
}

Servers

API Server (3080)

Business logic endpoints:

• /api/users - User management
• /api/orders - Order processing

Admin Server (3081)

Administrative endpoints:

• /admin/stats - System statistics
• /admin/config - Configuration management

Metrics Server (3082)

Monitoring endpoints:

• /metrics - Application metrics
• /health - Health checks

Use Cases

• Separation of concerns: Different ports for different audiences
• Security: Admin endpoints on internal port only
• Scaling: Scale each service independently
• Load balancing: Route traffic based on purpose
• Monitoring: Dedicated metrics endpoint
