Kubernetes the Hard Way with Vagrant

This repository provides a Vagrantfile to automate the setup of virtual machines required for Kubernetes the Hard Way by Kelsey Hightower.

Why Use Vagrant?

Setting up the virtual machines manually can be time-consuming and complex, especially for those not deeply familiar with virtualization. To simplify this process for students and professionals, I've created a Vagrantfile that automates the provisioning of the necessary environment. This allows you to focus on learning Kubernetes without the overhead of manual VM configuration.

Prerequisites

Mac with ARM architecture
Vagrant installed
VMware Desktop plugin for Vagrant

Installation Instructions

Install Vagrant

brew tap hashicorp/tap
brew install hashicorp/tap/hashicorp-vagrant

Install VMware Desktop Plugin for Vagrant

vagrant plugin install vagrant-vmware-desktop

Clone the Repository

git clone https://github.com/azalio/kubernetes-the-hard-way.git
cd kubernetes-the-hard-way

Start the Virtual Machines
```
vagrant up
```
This command will create four virtual machines configured according to the requirements of Kubernetes the Hard Way.

Included Files

Vagrantfile: Automates the setup of the virtual machines.
encryption-config.yaml: Necessary for completing the practice as of November 2024.

Getting Started

With the virtual machines up and running, you can proceed with the steps outlined in Kelsey Hightower's Kubernetes the Hard Way tutorial.

Why I Created This

As part of developing an advanced Kubernetes course for senior engineers, I recognized the need for hands-on practice. Manually assembling a Kubernetes cluster provides invaluable insights but can be daunting without the right setup. By automating the virtual machine provisioning with Vagrant, I aimed to:

Reduce Setup Time: Eliminate the hassle of manual VM configuration.
Enhance Learning: Allow learners to focus on Kubernetes concepts rather than infrastructure setup.
Facilitate Teaching: Provide a consistent environment for all students in the course.

Let's make Kubernetes the Hard Way more accessible and focus on mastering the essentials!

Kubernetes The Hard Way

This tutorial walks you through setting up Kubernetes the hard way. This guide is not for someone looking for a fully automated tool to bring up a Kubernetes cluster. Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.

The results of this tutorial should not be viewed as production ready, and may receive limited support from the community, but don't let that stop you from learning!

Target Audience

The target audience for this tutorial is someone who wants to understand the fundamentals of Kubernetes and how the core components fit together.

Cluster Details

Kubernetes The Hard Way guides you through bootstrapping a basic Kubernetes cluster with all control plane components running on a single node, and two worker nodes, which is enough to learn the core concepts.

Component versions:

kubernetes v1.28.x
containerd v1.7.x
cni v1.3.x
etcd v3.4.x

Labs

This tutorial requires four (4) ARM64 based virtual or physical machines connected to the same network. While ARM64 based machines are used for the tutorial, the lessons learned can be applied to other platforms.
