How to Install Kubernetes on Ubuntu VM
If you’re looking to set up a Kubernetes cluster on an Ubuntu virtual machine, you’ve come to the right place. In this guide, we’ll walk you through the step-by-step process of installing and configuring Kubernetes on your Ubuntu VM.
Prerequisites
Before we begin, make sure you have the following prerequisites:
- An Ubuntu virtual machine with internet access
- SSH access to your Ubuntu VM
- Root privileges or access to a user with sudo privileges
Step 1: Update and Upgrade Ubuntu
First, SSH into your Ubuntu virtual machine and update the package list and upgrade the installed packages by running the following commands:
sudo apt update
sudo apt upgrade -y
Step 2: Install Docker
Kubernetes relies on Docker to run its containerized applications. Install Docker on your Ubuntu VM by executing the following commands:
sudo apt install docker.io -y
sudo systemctl enable docker
sudo systemctl start docker
Step 3: Install Kubernetes
Now, it’s time to install Kubernetes on your Ubuntu VM. Run the following commands to add the Kubernetes repository, install the necessary packages, and enable the Kubernetes service:
sudo apt install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"
sudo apt update
sudo apt install -y kubeadm kubelet kubectl
sudo systemctl enable kubelet
sudo systemctl start kubelet
Step 4: Initialize the Kubernetes Cluster
Finally, initialize the Kubernetes cluster on your Ubuntu VM by running the following command:
sudo kubeadm init
Follow the instructions provided by the command to set up your Kubernetes cluster. Once the initialization process is complete, you’ll have a fully functioning Kubernetes cluster running on your Ubuntu VM.
Congratulations! You have successfully installed Kubernetes on your Ubuntu virtual machine. You can now start deploying and managing containerized applications with ease. Happy containerizing!
