After installing minikube on my Ubuntu VM which is running in Vagrant, on top of my windows 10 desktop. I started to notice some performance issues which ended up with frequent minikube restarts and constant VM reboots. Then on the internet, I found another way or actually two ways to run my k8s cluster lab setup on my local virtual environment using KIND  & MicroK8s , which i would like to share with the community. So the steps are as follows, So, what is KIND ? KIND is a tool that allows you to run local Kubernetes clusters using Docker container “nodes”. It is primarily designed for testing Kubernetes itself, but it can also be used for local development or continuous integration (CI). With KIND, you can create a Kubernetes cluster within minutes. It supports multi-node (including high availability) clusters and building Kubernetes release builds from source. First lets build our VM using Vagrant and Virtualbox, you can get the steps from here . Setting up the Vagrant directory

Introduction: In the ever-evolving world of technology, two terms often thrown around are Site Reliability Engineering (SRE) and DevOps. They sound fancy, but what do they really mean? Are they the same thing, or do they have their own unique roles in the tech landscape? Let's break it down in simple terms. Understanding DevOps: DevOps, short for Development and Operations, is like a magical bridge that connects software development with IT operations. Imagine it as a team of wizards ensuring that the code developers create not only works flawlessly but also smoothly integrates with the infrastructure it runs on. In simpler terms, DevOps is all about teamwork and collaboration. Developers and operations folks come together, share responsibilities, and work hand-in-hand to build, test, and deploy software. The goal? Faster and more reliable delivery of applications. Meet the SRE Heroes: Now, enter the Site Reliability Engineer, or SRE. If DevOps is the magical bridge, SREs are the g

DevOps and GitOps are two popular models for software development that have gained traction in recent years. While both models share some similarities, they differ in several key ways. What is DevOps? DevOps is a software development model that emphasizes collaboration between development and operations teams. The goal of DevOps is to make the software development process faster and more efficient by improving communication between teams and automating certain tasks. What is GitOps? GitOps is a newer model that builds on the principles of DevOps. GitOps uses Git as the single source of truth for infrastructure and application code deployments. This means that all changes to the system are tracked in Git, making it easier to manage and deploy changes. GitOps also emphasizes automation and observability. How is GitOps Different from DevOps? The main difference between GitOps and DevOps is that GitOps uses Git as the single source of truth for infrastructure and application code deploymen
