I am writing an enhanced tutorial for deploying kubernetes cluster on a limited resource system.

Highlights:

• This tutorial is based upon rgmorales ’s k8s hard way on LXD
• Upgraded the base tutorial to use K8s updated version 1.22.3
• Used Multipass virtual system to host the Ubuntu Hosting machine

If you have very little available memory (say 8GB), I recommend going with this option. Install Multipass. Going through my tutorial you will be able to run the entire k8s cluster (3 Master Nodes with etcd cluster + 3 worker nodes and 1 Ingress load balancer (haproxy) to k8s cluster ). More importantly this entire cluster used less than 2GB of my laptop memory.

In this tutorial you will learn the following

• Multipass Install Instructions
• Prerequisites
• Installing the Client Tools
• Setting up Compute Resources
• Provisioning the CA and Generating TLS Certificates
• Generating Kubernetes Configuration Files for Authentication
• Generating the Data Encryption Config and Key
• Bootstrapping the etcd Cluster
• Bootstrapping the Kubernetes Control Plane
• Bootstrapping the Kubernetes Worker Nodes
• Configuring kubectl for Remote Access
• Deploying the DNS Cluster Add-on
• Smoke Test the cluster
• Cleaning Up activities

Note: The above lab takes typical 1-2 hours to setup and run all the above items.
