Kubernetes. What and How?

Introduction

In this part of the workshop you are going to get Minikube running on your local computer.

We are using Minikube because that is the easiest way to demonstrate how kubernetes works and what we can do with it. Minikube is a tool that runs a single-node Kubernetes cluster in a virtual machine on your personal computer.

To be able to run minikube you also need to install Docker and kubectl.

Tasks

1. Install Minikube

Read the instructions on how to install Minikube here, on macOS the short version is:

$ brew install minikube
$ minikube start

Verify Minikube installation

You can verify that Minikube is up and running on your computer by running the following command:

$ minikube status

2. Install kubectl

In order to manipulate the Kubernetes cluster you need to install the official CLI client called kubectl.
