Kubernetes is an open-source platform that makes it easy to deploy, manage, and scale containerized applications. It provides a way to automate the deployment, scaling, and management of applications, making it an essential tool for organizations that are looking to take advantage of the benefits of containerization.

In this tutorial, we will guide you through the process of installing and setting up a Kubernetes cluster, so you can start using it to manage your applications.

Step 1: Install Docker

The first step in getting started with Kubernetes is to install Docker. Docker is a containerization technology that provides a way to package and run applications in containers. Kubernetes is designed to work with Docker containers, so it is important that you have Docker installed on your system before you begin.

Step 2: Install kubectl

kubectl is the command-line interface (CLI) tool that you use to manage your Kubernetes cluster. To install kubectl, follow the instructions for your operating system from the official Kubernetes documentation.

Step 3: Install a Kubernetes cluster

There are several ways to install a Kubernetes cluster, including using a managed service such as Google Kubernetes Engine (GKE) or Amazon Elastic Kubernetes Service (EKS), or by installing it manually using tools such as Minikube or kubeadm.

For the purpose of this tutorial, we will use Minikube, a tool that makes it easy to set up a single-node Kubernetes cluster on your local machine for development and testing purposes. To install Minikube, follow the instructions for your operating system from the official Minikube documentation.

Step 4: Start the cluster

Once you have installed Minikube, you can start the cluster by running the following command:

Type command: minikube start

Step 5: Verify the installation

To verify that your Kubernetes cluster is up and running, you can use the following command:

Type command: kubectl get nodes

This command should display a list of the nodes in your cluster, including the single node that is running in Minikube.

Step 6: Deploy an application

Now that your Kubernetes cluster is up and running, you can start deploying applications to it. To demonstrate this, we will deploy a simple web application that displays "Hello, World!" in a web browser.

To deploy the application, create a file called hello-world.yaml with the following content:

#code :

apiVersion: apps/v1

kind: Deployment


name: hello-world

spec: replicas: 1 selector: matchLabels: app: hello-world template: metadata: labels: app: hello-world spec: containers: - name: hello-world image: ports: - containerPort: 8080

This file defines a deployment that creates a single replica of the hello-world application and runs it in a container. The container uses the `
