PART 01 - PREREQUISITES

https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/01-prerequisites.md

We had a cpu lying with lots of space at SDSLabs. Although I use Mac M1, it doesn’t have enough space as mentioned. Maybe it could have run but i decided to setup 3 vm’s (server’s and node) on the the ubuntu installed system. (let’s call it poseidon)

For creating the vm’s, I chose qemu. Part of the reason being comfortable with it and subtle dislike for virtualbox. And it’s a learning project, so I honestly don’t care about any performance overhead.

Configuring Qemu

Enable Virtualization

egrep -c '(vmx|svm)' /proc/cpuinfo

If output is zero, look up on net how to enable it for your device, should be straigtforward.

Install Qemu and download Debian Image

sudo apt update
sudo apt install qemu-system qemu-utils qemu-efi-aarch64
wget <replace with link of the iso from : https://cdimage.debian.org/debian-cd/current/arm64/iso-cd/>

Also, make sure your user is the root user, if not, you’ll have to make sure it is added to the respective groups if required. I have root privileges, so skipping this part.
