Building a High-Availability Ingress Solution with Envoy Proxy on Kubernetes

Moving from External Load Balancer to Cloud-Native Architecture

The Challenge

In on-premise Kubernetes deployments, achieving high availability for ingress traffic often relies on external load balancers running on dedicated VMs. While functional, this approach creates single points of failure, adds operational complexity, and wastes valuable infrastructure resources.

In this guide, I’ll walk you through migrating from an external Envoy load balancer to a fully integrated, Kubernetes-native solution using DaemonSet deployments, Keepalived for VIP management, and host networking for optimal performance.

A Complete Guide to Kubernetes CRDs: Definition, Uses , Benefits, and Error Fixes

Hi Everyone , Today we are trying to understand CRDs(Custom Resource Definitions) as I was working on one Observability project in OpsTree Global and suddenly found CRD errors and let me tell you, It was very Frustration. I will try to make you understand them in easy way, so that you don’t need to make another doc of knowledge. Comment if you will have any doubts.

Modern Traffic Management with Gateway API in Kubernetes

Managing traffic in Kubernetes is like directing cars at a busy intersection. If everything flows smoothly, the system works like a charm. But if traffic gets out of control, you’ll end up with a gridlock—applications slow down, and users get frustrated.

For years, Ingress was the go-to traffic cop for Kubernetes. It handled requests, routed them to the right places, and kept things moving. But as workloads grew more complex and modern, Ingress started to feel like using paper maps in a GPS world. Enter the Gateway API—the next-gen solution built to handle today’s dynamic application demands. Continue reading “Modern Traffic Management with Gateway API in Kubernetes”

Extending K8S API

Ever found yourself thinking, “Kubernetes is awesome, but I wish it could do this specific thing just for my setup”? Well, guess what? It probably can. Kubernetes isn’t just about managing those swanky Pods and Services; it’s like a LEGO set, and with the right pieces, you can build pretty much anything.

Enter the world of Custom Resource Definitions, or CRDs for the cool kids. Imagine being able to teach your Kubernetes new tricks without waiting for the next big release. That’s exactly what CRDs let you do!

In this blog post, we will explore how to extend the Kubernetes API with Custom Resource Definitions (CRDs).

What are Kubernetes Events ?

Hi Guys !! I am back with another blog where we learn concepts both in Traditional and Hilarious way.

So What are waiting for “CHRISTMAS “ 🎄 Duhh Let’s go .

Kubernetes Events

Boring Version💤

Kubernetes Events are records of significant changes or occurrences within a Kubernetes cluster. They provide insights into what is happening inside the cluster, helping administrators and developers troubleshoot issues, monitor the system, and understand the behavior of Kubernetes objects.

Funny Version 😂

Imagine your Kubernetes cluster is a bustling city, and events are like the city’s wildest news headlines. Picture this: “Pod Pete Lands a New Gig, Buys Everyone Virtual Donuts!” or “Node Nancy Calls in Sick, Blames Her Wi-Fi for Playing Hooky!” Every time something crazy happens — whether it’s a pod getting a new assignment or a node mysteriously disappearing for a “coffee break” — an event gets published to keep the whole Kubernetes town buzzing with the latest gossip.
