Ever wished your AI assistant could actually remember things between conversations? Not just the current chat, but the architectural decisions you made three months ago, the patterns your team agreed on, or that obscure networking fix you discovered at 2 AM? We built exactly that, a persistent, searchable long-term memory
Say goodbye to downtime when you need more storage Running out of disk space on a production VM is stressful enough without the added headache of scheduling a reboot. The good news? If you're running Linux on VMware, you can expand your disk and have the guest OS
Preface: If you're running Jenkins in an internal datacenter and using Bitbucket Cloud for source control, you've likely hit this wall: Bitbucket can't send webhooks to Jenkins because your Jenkins server isn't publicly accessible. The typical workaround? Having Jenkins poll every repository
Monitoring HAProxy is essential for maintaining reliable load balancing infrastructure. Prometheus provides powerful metrics collection, alerting capabilities, and seamless Grafana integration for visualizing HAProxy performance and health. Why Prometheus for HAProxy? Prometheus offers: * Pull-based metrics - Prometheus scrapes HAProxy metrics endpoints * Time-series database - Store historical data for trend analysis
In dynamic environments where services scale up and down automatically, static HAProxy configurations become a management burden. Consul integration enables HAProxy to automatically discover and route traffic to healthy service instances without manual configuration updates. Why Consul + HAProxy? The combination provides: * Automatic service registration - Services announce themselves to Consul
Managing HAProxy configuration traditionally requires editing files and reloading the service. The Data Plane API transforms HAProxy into a dynamically configurable load balancer with a RESTful interface, enabling real-time configuration changes without service interruption. Why Data Plane API? The Data Plane API provides: * Runtime configuration - Add/remove backends and
Mutual TLS (mTLS) provides strong authentication by requiring both client and server to present certificates. This guide shows how to configure HAProxy for mTLS to secure API endpoints, internal services, and zero-trust networks. What is mTLS? In standard TLS, only the server presents a certificate. With mTLS: 1. Server presents
When applications misbehave behind a load balancer, HTTP headers are often the culprit. This guide shows you how to debug, inspect, and manipulate HTTP headers in HAProxy to troubleshoot web application issues. Why Header Debugging Matters HTTP headers control critical aspects of web traffic: * Client IP forwarding (X-Forwarded-For) * Protocol information
HTTPS is no longer optional - it's a requirement for modern web applications. This guide shows how to integrate HAProxy with Let's Encrypt for fully automated TLS certificate provisioning and renewal, giving you secure HTTPS without manual certificate management. Overview The integration involves: 1. HAProxy serving
DNS is critical infrastructure - when DNS fails, nothing works. This guide shows how to use HAProxy to load balance DNS queries across multiple resolvers or authoritative servers, providing high availability and improved performance for your DNS infrastructure. Why Load Balance DNS? DNS load balancing offers several benefits: * High availability:
HAProxy is one of the most powerful and reliable load balancers available. While it's often associated with HTTP load balancing, HAProxy excels at Layer 4 (TCP) load balancing for any TCP-based protocol. This guide covers everything you need to know about TCP load balancing with HAProxy. Why TCP
A well-monitored DNS infrastructure provides visibility into query patterns, performance bottlenecks, and potential security issues. This final post in the BIND series covers setting up comprehensive monitoring using Prometheus and Grafana, giving you dashboards and alerts for your DNS servers. BIND Statistics Overview BIND provides extensive statistics through several channels:
