Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# Starting minikube to create a cluster

minikube has made creating a cluster as easy as it can get. All we need to do is to execute a single command. Minikube will start a virtual machine locally and deploy the necessary Kubernetes components into it. The VM will get configured with Docker and Kubernetes via a single binary called **localkube**.




# A note to windows users

You might experience problems with VirtualBox. If that's the case, you might want to use *Hyper-V* instead. 

* Open a Powershell Admin Window and execute the `Get-NetAdapter` command. Note the name of your network connection. 

* Create a `hyperv` virtual switch `New-VMSwitch -name NonDockerSwitch -NetAdapterName Ethernet -AllowManagementOS ＄true` replacing `Ethernet` with your network connection name. 
* Then, create the minikube VM: `minikube start --vm-driver=hyperv --hyperv-virtual-switch "NonDockerSwitch" --memory=4096`. 

Other minikube commands such as `minikube start`, `minikube stop`, and `minikube delete` all work the same whether you're using VirutalBox or Hyper-V.

A few moments later, a new minikube VM will be created and set up, and a cluster will be ready for use.

# Understanding the process
When we execute the `minikube` start command, it creates a new VM based on the minikube image. This image contains a few binaries. It has both [Docker](https://www.docker.com/) and [rkt](https://www.redhat.com/en/topics/containers/what-is-rkt) container engines as well as the localkube library.
> **Note:** **rkt** is an application container engine developed for modern production cloud-native environments. 

The *localkube* library includes all the components necessary for running Kubernetes. We'll go into details of all those components later. For now, the important thing is that localkube provides everything we need to run a Kubernetes cluster locally.
