Are you looking for how to install Kubernetes on Ubuntu? This blog is designed for you. In this blog, we will delve into Kubernetes and learn how to install Kubernetes on the Ubuntu Operating system. We will also know the prerequisites to install Kubernetes, what Kubernetes is, and why it is used. Once you complete reading the blog, you will know how to install Kubernetes on Ubuntu.
Software development is constantly evolving along with the rest of the technology world. Developers now depend on containerization to build and deploy applications more quickly. Kubernetes is one of the container orchestration tools that developers and DevOps engineers prefer to manage their resources effectively.
As you know, Ubuntu is one of the operating systems widely used by many companies worldwide. It is an open-source software that provides high security to its applications and resources.
In this blog, we will go over how to install Kubernetes in the Ubuntu operating system. The step-by-step procedure will help you to install Kubernetes on Ubuntu smoothly. Also, you will learn the basics of Kubernetes and Ubuntu in addition to the perquisites to install Kubernetes on Ubuntu. Let’s start now!
Ubuntu is a Linux-based open-source operating system that you can use on your computer or virtual private server. Ubuntu serves as a standard Kubernetes platform on all the major public clouds.
Kubernetes is a container orchestration framework created by Google. In a nutshell, it's like a master Lego Builder who assists you in efficiently managing and organizing all of the Lego pieces (your software applications). Where you run Kubernetes is up to you, as it is inherently portable.

Some of the key features that make Kubernetes a popular choice for container orchestration are:
Following are the software and hardware prerequisites to install Kubernetes on Ubuntu.

Let's go to the step-by-step procedure to install Kubernetes on Ubuntu.
Step 1: First, update system packages in the Linux terminal using the following command:
sudo apt-get update
Step 2: Once system packages are updated, then install a transporter. Note that transport is one of the essential components required for Kubernetes installation. You can install a transporter using the following command.
sudo apt-get install -y apt-transport-https
Next, you must install Docker to coordinate with Kubernetes. For this, you must use the below command.
sudo apt install docker.io
Step 3: Soon after Docker is installed, you must start and enable Docker. Otherwise, it won't provide permission to install Kubernetes. Mainly, it can be done using the below commands.
sudo sysemctl start docker sudo systemctl enable docker
Step 4: To enable the execution of multiple dependencies and auto updates of Kubernetes to prevent it from malfunctioning, we will require 'Curl' on our Linux machine. You must use the command "sudo apt-get install curl" to do so. Now moving to the core!!
Step 5: Now we will be installing Kubernetes. Kubernetes consists of four main components Kubelet, kubeadm, Kubectl, and Kubernetes. But before that, we have to download some crucial packages and dependencies, which can be done by using the command.
sudo curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg| sudo apt-key add ok Sudo chmod 777/etc/apt/sources.list.d/kubernetes.list.d/
Also, to install all four types, we can use the below command:
sudo apt-get install -y kubelet kubeadm kubectl kubernetes-cni
Step 6: Moving further, we will configure Kubernetes using the commands “sudo swapoff -a” and "sudo kubeadm init". After that, you can start Kubernetes and configure it.
Step 7: Right now, we have started our Kubernetes, and now it's successfully initiated and operational.

You can install Kubernetes on clouds, on-premises, and in data centers.
It depends on specific requirements. However, a typical Kubernetes cluster will need a dozen worker nodes and two master nodes for installation.
Every node in a Kubernetes cluster must have the following:
Single-container pods and multi-container pods are the two types of pods available in Kubernetes.
Totally, 256 pods can run on a single node in a standard Kubernetes cluster.
We need a minimum of 2GB of memory to install Kubernetes. It will include eight nodes, and each node will contain 40 pods.
Kubernetes supports both Linux and Windows operating systems.
