Kubecon NA 2023 - Breaking your Cluster - This is a WIP!!!!

Learning Kubernetes by Chaos - Breaking a Kubernetes cluster to understand the components

This repo contains a set of scripts/programs that will help you to have your own broken Kubernetes cluster, and then fix it.

WORK IN PROGRESS - This repo is a Work in Progress and we plan to document all the items we covered during the presentation + some additional docs!!

Pre requisites

• Kubectl
• Docker
• KinD

Getting started

• Clone this repo: git clone https://github.com/rikatz/kubeconna-2023.git

• Run make start After this you will have a kind clusters and you should expect a functional kind cluster.

• Run make break With this make break everything should be broken (duh).

• Run make help if you want to explore other possible make targets.

• Run make deploy-app DEPLOY_NAME=app1

• Run make deploy-app DEPLOY_NAME=app2

And start fixing the cluster until the Pods start running and you can call one and other using services.

A valid output would be, from any pod of "app1", doing:

curl http://app2:9000

And receiving a Hello World!!!
