Kubernetes Lab Setup

This repository contains the relevant steps to setup

• 1 Alpine OS Management Server
• 1 single node Lightweight Kubernetes ( k3s)
• 1 High Available Cluster Lightweight Kubernetes ( k3s)

The objective of this lab is to be able to rebuild the clusters very quickly as this is for testing services and applications.

Files required for the setup can be extracted from the git repository https://github.com/belajarpowershell/kubernetes-lab

The guide is designed such that , someone with basic knowledge of Ubuntu , can setup the lab succesfully. Basic knowledge of Ubuntu only requires connecting, navigating and editing files .

Follow the sequence number in the files , this will ensure that all the required services are setup.

Here is a high level on the tasks required .

Operating System Setup 100-alpine1

• Clone the repository to the Hyper V host. (step 003-clone-repository)
• Create the Virtual machines required using the PowerShell script. ( step 004-Hyper-V-VM-creation )
• Setup Alpine Linux on VM alpine1 .(step 100-alpine1-setup)
• Connect to alpine1 via ssh (step 101-ssh-to-alpine1 )
• Clone the repository on alpine1 ( step 102-Clone-repository)
• Setup on alpine1 the various services required . (step 103-setup-using-ansible)
• Install Ubuntu OS on the remaining Virtual Machines ( loadbalancer,master1/2/3,worker1/2/3,singlenode) (step113-generate-user-data-multipleVM )
