How to Install Kubernetes on Ubuntu 22.04

Kubernetes is an open-source container orchestration platform that enables the deployment, scaling, and management of containerized applications. It is an efficient tool that automates the deployment and management of applications in a cluster of nodes. In this article, we will explore how to install Kubernetes on Ubuntu 22.04.

Prerequisites

Before we begin, make sure you have the following prerequisites:

  1. Ubuntu 22.04 installed on your system.
  2. A user account with sudo privileges.
  3. A reliable internet connection.

Step 1: Update the system

Before installing Kubernetes, it is essential to update the system to the latest version. To do this, run the following command in the terminal:

sudo apt-get update
sudo apt-get upgrade

Step 2: Install Docker

Kubernetes uses Docker to run containers. To install Docker, run the following commands:

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce

To check if Docker is installed, run the following command:

docker --version

Step 3: Install Kubernetes

To install Kubernetes, we will use the snap package manager. Run the following command to install the snap package manager:

sudo apt-get install snapd

Once the snap package manager is installed, run the following command to install Kubernetes:

sudo snap install microk8s --classic

Step 4: Configure Kubernetes

After installing Kubernetes, we need to configure it by enabling required add-ons. Run the following commands to enable the add-ons:

sudo microk8s enable dashboard dns registry istio

To check the status of the add-ons, run the following command:

sudo microk8s status

Step 5: Access Kubernetes Dashboard

To access the Kubernetes dashboard, run the following command:

sudo microk8s dashboard-proxy

This will start the Kubernetes dashboard, and you can access it by navigating to http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/ in your web browser.

In this article, we learned how to install Kubernetes on Ubuntu 22.04. Kubernetes is a powerful tool that simplifies the deployment and management of containerized applications. By following the steps mentioned above, you can easily install Kubernetes and start deploying your applications in a cluster of nodes.
