+
+```shell
+mkdir -p $HOME/.kube
+sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
+sudo chown $(id -u):$(id -g) $HOME/.kube/config
+```
+
+## Install CNI
+We choose Cilium
+https://docs.cilium.io/en/stable/gettingstarted/k8s-install-helm/
+
+```shell
+helm repo add cilium https://helm.cilium.io/
+helm install cilium cilium/cilium --version 1.11.5 --namespace kube-system
+```
+
+## (Optional) Remove taint for single node use
+```shell
+kubectl taint nodes --all node-role.kubernetes.io/control-plane- node-role.kubernetes.io/master-
+```
+
+## Deploy using Terraform
+https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs/guides/getting-started
+```shell
+terraform plan 
+terraform apply
+```
+
+## Cleanup
+```shell
+kubectl drain <node name> --delete-emptydir-data --force --ignore-daemonsets
+kubeadm reset
+```
