Implement Kubernetes network policies with Calico for microsegmentation
Configure Calico CNI to enforce network policies for pod-to-pod traffic control and namespace isolation. This tutorial covers advanced microsegmentation patterns, ingress/egress rules, and policy monitoring for production Kubernetes security.
Configure Cilium BGP peering with MetalLB integration for Kubernetes load balancing
Set up Cilium CNI with BGP routing capabilities and integrate with MetalLB speaker components for bare-metal Kubernetes load balancing. This configuration enables external traffic routing and service discovery in on-premises environments.
Setup HAProxy with Docker container backends for dynamic load balancing
Configure HAProxy 2.8 to automatically discover and load balance traffic across Docker containers with health checks, service discovery, and SSL termination for production-grade dynamic routing.
Configure HAProxy advanced routing with ACLs and maps for intelligent traffic management
Set up sophisticated traffic routing in HAProxy using Access Control Lists (ACLs) and map files for dynamic backend selection, SSL SNI routing, and intelligent request distribution based on headers, paths, and custom conditions.
Configure WireGuard site-to-site VPN connections with advanced routing and security
Set up secure network-to-network VPN tunnels using WireGuard with advanced routing, firewall rules, and monitoring for connecting multiple office locations or data centers.
Configure HAProxy multi-site SSL termination with SNI for secure load balancing
Set up HAProxy to handle SSL certificates for multiple domains using Server Name Indication (SNI), enabling secure HTTPS traffic termination and load balancing across different backend services.
Configure HAProxy SSL termination with Let's Encrypt and security headers
Set up HAProxy 2.8 with SSL termination, automatic Let's Encrypt certificates, and security headers for high-performance load balancing with HTTPS offloading and automated certificate renewal.
Configure Tailscale with Kubernetes cluster networking integration
