Using Kyverno To Enforce EKS Best Practices

Hey folks, in this post we’ll see how you can use Kyverno to enforce some best practices for your EKS cluster. For those not familiar, Kyverno is a Kubernetes native policy engine that aims to make your life easy when managing clusters. To know more you can read my previous post on Kyverno where we discuss the project and its internals in detail. With that out of the way, let’s get started!...

Channels In Golang

This is the final post in my “Do You Concur?” series. If you’ve not checked the other two out it is highly recommended you do that before reading this one. With that out of the way let’s get started! What Are Channels? A channel in Go can be best understood by comparing it with a box. It is a box where goroutines can put and take out the data. So essentially channels help your goroutines to share data....

Race Conditions In Golang

This post is the second in my series of articles on Concurrency in Go. In this post, we’ll understand what a race condition is, the why and how of it, and finally, we see some code that creates a race condition, and then we will learn to fix that race condition with the help of Mutexes. So let’s get started! The What, Why And How Of A Race Condition A race condition in Go occurs when two or more goroutines have shared data and interact with it at the same time....

Concurrency In Golang

I recently started learning more about concurrency in golang and so as with other things I learn, I decided to write about it. This article will be a part of a short series I plan to write about concurrency in Go. So let’s get started! Concurrency Vs Parallelism Before we start looking at some code, I think it would be better to know what concurrency actually is. But even before we do that let us first talk about parallelism because it is a word that often comes up when talking about concurrency....

Pod Health With Liveness Probes

Kubernetes relies on Probes to determine the health of a Pod container. A probe can be understood simply as a periodical diagnostic performed by the kubelet on the container. In this short article, I’m going to show you a liveness probe in action. Liveness probes are used to check if a Pod is healthy (running as expected) or not. It simply acts as a check for Kubernetes to know when it should restart the container....
