Start Docker Desktop, then start Minikube to create a VM and a Kubernetes cluster on that machine with the following command:

minikube start --driver=docker

If starting Minikube fails, try deleting with this command and retry again:

minikube delete

You can run this command to check the Minikube status

minikube status

In your terminal, go to the terraform directory

cd ./terraform

In variables.tfvars, set the path to your .kube/config folder. It is where Kubernetes store its config files. On Windows, usually its $env:userprofile/.kube/config. So in a powershell terminal, type $env:userprofile to get the first part of the path. If you are using \ in the path, make sure to escape it with \\. Then initialize Terraform

terraform init

Then apply the tf files to configure the cluster

terraform apply -var-file="variables.tfvars"

Use the following command to make sure the cluster is configured. You should see the namespace webgoat.

kubectl get namespaces

• Before configuring the cluster, you need to register an application on Google Console.
• Then you need to install Google Cloud SDK, and set up the project. The following command configures Google Cloud SDK to point to the project.

gcloud config set project ${{ secrets.PROJECT_ID }}
gcloud components install gke-gcloud-auth-plugin
gcloud container clusters get-credentials ${{ secrets.GKE_CLUSTER }} --region=${{ secrets.GKE_REGION }}

Then, in your terminal, go to the terraform/gke directory

cd ./terraform/gke

If you are running Terraform for the first time, intialize Terraform:

terraform init

If you updated the variables.tfvars file, apply the tf files to provision the cluster:

terraform apply
