• Before we set up the Kubernetes Goat, ensure that you have created and have admin access to the Kubernetes cluster

kubectl version --short

• Set up the helm version 2 in your path as helm2. Refer to helm releases for more information about setup

helm2 --help

• Then finally setup Kubernetes Goat by running the following command

git clone https://github.com/madhuakula/kubernetes-goat.git
cd kubernetes-goat
bash setup-kubernetes-goat.sh

• To export the ports/services locally to start learning, run the following command

bash access-kubernetes-goat.sh

• Then navigate to http://127.0.0.1:1234
