Deploying Kubernetes on Ubuntu 20.04 Focal Fossa

How to install Kubernetes on Ubuntu 20.04 Focal Fossa Linux

Kubernetes is leading software in container orchestration. Kubernetes works by managing clusters, which is simply a set of hosts meant for running containerized applications. In order to have a Kubernetes cluster, you need a minimum of two nodes – a master node and a worker node. Of course, you can expand the cluster by adding as many worker nodes as you need.

In this guide, we’re going to deploy a Kubernetes cluster consisting of two nodes, both of which are running Ubuntu 20.04 Focal Fossa. Having two nodes in our cluster is the most basic configuration possible, but you’ll be able to scale that configuration and add more nodes if you wish.

In this tutorial you will learn:

  • How to install Docker
  • How to install Kubernetes
  • How to configure a master and worker node
  • How to join a worker node to a Kubernetes cluster
  • How to deploy Nginx (or any containerized app) in a Kubernetes cluster
