Example Workflow: Create a new cluster and use it with kubectl

1. k3d create to create a new single-node cluster (docker container)
2. export KUBECONFIG=$(k3d get-kubeconfig) to make kubectl to use the kubeconfig for that cluster
3. execute some commands like kubectl get pods --all-namespaces
4. k3d delete to delete the default cluster
