What is Kubernetes? 🤔

Kubernetes, also known as K8s, is an open-source platform designed to automate deploying, scaling, and operating application containers. It helps you manage a cluster of Linux containers as a single system to streamline DevOps processes and ensure efficient resource utilization.

Why Kubernetes? 🌟

• Scalability: Automatically scale your applications up or down based on demand.
• Portability: Run Kubernetes on various environments like on-premises, cloud providers, or hybrid setups.
• Self-healing: Automatically replace or reschedule failed containers.
• Service Discovery & Load Balancing: Efficiently manage service discovery and load balancing.
• Automated Rollouts & Rollbacks: Seamlessly update your applications without downtime.

Getting Started 🚀

In this documentation, we'll cover everything from setting up your local machine with Minikube to deploying clusters on cloud providers like AWS (EKS), DigitalOcean, and more.

Setting Up Your Local Environment 🛠️

To start your Kubernetes journey, you'll first need to set up a local development environment. We recommend using Minikube for this purpose.

Prerequisites

• Docker: Ensure Docker is installed on your machine.
• Kubectl: Kubernetes command-line tool for interacting with the cluster.
• Minikube: Tool to run Kubernetes locally.

Installation Steps

1. Install Docker:

2. Install Kubectl:
   • Kubectl Installation Guide (opens in a new tab)
3. Install Minikube:
   • Minikube Installation Guide (opens in a new tab)

Once you have everything installed, you can start your Minikube cluster with:

minikube start

You're now ready to explore the power of Kubernetes!
