Prerequisite

This section will guide you through installing kubectl, the Kubernetes CLI, and setting up minikube a small cluster that can run on your local machine.

The tutorial was tested on minikube, but should work with any recent Kubernetes version, so feel free to use any alternative like kind or production grade clusters from Infrastructure Providers (maybe you have some free compute time left) like AWS.

For some parts of the tutorial, you will need an ingress controller installed, we will see what this is later on. minikube comes with a command to set up NGINX [1], so it is recommended to use it too, when working with a different cluster.

Installing kubectl#

Kubectl is the CLI that allows you to interact directly with the Kubernetes API server and thus is the main way of interacting with clusters. During the tutorial you will learn more about, for now just install it by following the kubectl installation instructions [2].

Setting up minikube#

To install minikube on your computer, use the minikube installation instructions [3].

Since you will already have Docker installed, you will not necessarily need another hypervisor, but Docker can be quite unstable when it comes to networking and ingresses. So it's recommended to install for example VirtualBox, except if you are on MacOS where you will already have the HyperKit hypervisor installed.

Minikube Cheat Sheet#

Start minikube

minikube start

Start minikube in VM mode (hypervisor not Docker)

minikube start --vm=true

Stop minikube

minikube stop

Enable the ingress controller (recommended to use VM mode)

minikube enable addons ingress
