How to Run Kubernetes on Windows

Kubernetes is a popular container orchestration system that can help manage, scale and deploy containerized applications. While Kubernetes is typically associated with Linux, it's also possible to run Kubernetes on Windows. In this article, we'll cover the steps necessary to run Kubernetes on Windows, including installing Docker and Kubernetes, configuring Kubernetes, and deploying a sample application.

Prerequisites

• A Windows 10 or Windows Server 2019 machine
• A PowerShell terminal
• Administrative privileges

Step 1: Install Docker for Windows

The first step in running Kubernetes on Windows is to install Docker for Windows. Docker for Windows provides the necessary components for running and managing containers. To install Docker for Windows, follow these steps:

• Download Docker for Windows from the Docker website.
• Run the installer and follow the prompts to install Docker.
• Once installed, Docker will automatically start and run in the background.

Step 2: Enable Kubernetes in Docker

Once Docker is installed, you need to enable Kubernetes support. To do this, follow these steps:

• Open the Docker settings by right-clicking on the Docker icon in the taskbar and selecting "Settings."
• Click on the "Kubernetes" tab and select the "Enable Kubernetes" checkbox.
• Click "Apply" to save the changes.

Step 3: Deploy a Kubernetes Cluster

With Kubernetes support enabled in Docker, the next step is to deploy a Kubernetes cluster. To do this, follow these steps:

• Open a PowerShell terminal as an administrator.
• Use the following command to deploy a Kubernetes cluster:

  kubectl config use-context docker-for-desktop
  

• Verify that the Kubernetes cluster is running by using the following command:

  kubectl cluster-info
  

Step 4: Deploy a Sample Application

With the Kubernetes cluster up and running, the next step is to deploy a sample application. To do this, follow these steps:

• Create a file named "nginx.yaml" with the following content:

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: nginx-deployment
  spec:
    selector:
      matchLabels:
        app: nginx
    replicas: 1
    template:
      metadata:
        labels:
          app: nginx
      spec:
        containers:
        - name: nginx
          image: nginx:latest
          ports:
          - containerPort: 80
  ---
  apiVersion: v1
  kind: Service
  metadata:
    name: nginx-service
  spec:
    selector:
      app: nginx
    ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  

• Use the following command to deploy the application:

  kubectl apply -f nginx.yaml
  

• Verify that the application is running by using the following command:

  kubectl get pods
  

In this article, we covered the steps necessary to run Kubernetes on Windows. By following these steps, you should now have a working Kubernetes cluster on your Windows machine, as well as a deployed sample application. With this setup, you can begin exploring the many possibilities of container orchestration with Kubernetes.
