networkingConfigure HAProxy with Consul for dynamic service discovery and automatic backend updates
Build a self-updating load balancer by integrating HAProxy with Consul service discovery, consul-template, and health checks so backends register and deregister automatically without manual reloads.
Implement HAProxy WAF integration with ModSecurity 3 for advanced threat protection
Deploy ModSecurity 3 as a Stream Processing Offload Agent in front of HAProxy to inspect HTTP traffic with the OWASP Core Rule Set. This tutorial covers SPOA compilation, SPOE filter configuration, detection versus blocking modes, and production tuning.
Set up HAProxy SSL termination with Let's Encrypt certificates
Learn how to terminate SSL/TLS at HAProxy using Let's Encrypt certificates, redirect HTTP to HTTPS, automate renewal with deploy hooks, and harden your cipher suites for production load balancing.
Configure HAProxy with Consul for dynamic service discovery
Learn how to combine HAProxy, Consul and consul-template to build a self-updating load balancer that discovers backends automatically, reacts to health checks, and reloads without downtime.
Configure Jaeger authentication with OAuth2 and RBAC for enterprise security
Set up enterprise-grade authentication for Jaeger distributed tracing using OAuth2 with Keycloak integration and role-based access control policies for secure production deployments.
Setup Node.js error tracking with Sentry for production monitoring and debugging
