There are tons of articles available on the internet on the basics of how to run something, but there is a huge gap when you run something just to test it out and run it in production. A lot of tools will break when they start working at scale. In this series, we are going
Kubernetes has gained a lot of traction recently and is one of the standards followed across organizations when it comes to running and managing their containerized workloads. In this article, we are going to talk about Kubernetes operators. Usage Operators are used to running applications and tools on Kubernetes, like Redis Operator, Flink Operator, Istio
In our previous article series on Basics on Kubernetes which is still going, we talked about different components like control plane, pods, etcd, kube-proxy, deployments, etc. You can read the article series on Learnsteps. In this article, we are going to see how we can do basic debugging in Kubernetes. Before starting I am assuming
In one of my organizations, most of our Redis infrastructure runs on Kubernetes. if you know about the Redis cluster, you can connect to shards using the IP of the machines. Since we are running Redis in statefulsets, we have exposed the IPs of the pods inside our infrastructure. Kubernetes cluster is EKS and the
We have always focused on learning paths that can help you in longer and more in-depth knowledge. In this article, we are going to talk about what you can learn from Kubernetes from long-term perspective. When we talk about Kubernetes there are multiple components to it and basic deployment ways also have a lot of

Hi in this article we will talk about a very easy DevOps interview question. How to kill a running process. Earlier we have talked about VPC design, logging system design, monitoring system design, page fault, etc. kill, pkill and killall So we can use kill, pkill and killall commands to kill a process in Linux. All of these
In our previous interview-related question we talked about VPC design, logging system design, monitoring system design, page fault, etc. In this article, we are going to talk about how to calculate how many usage IPs are there in a /24 CIDR. What is a CIDR? CIDR stands for classless inter-domain routing. This is a set
In the previous article of the series, Basics on Kubernetes we talked about deployments in Kubernetes. You can read about it at the below link. In this article, we are going to talk about statefulsets, their similarity, and differences with deployments. What exactly is a Statefulset? Statefulsets are like deployments, they also manage pods that
