Here is an example on how to do that\n\nSave the new encryption config file to /etc/kubernetes/enc/enc.yaml on the control-plane node. Edit the manifest for the kube-apiserver static pod: /etc/kubernetes/manifests/kube-apiserver.yaml so that it is similar to\n\nBounded code example (external data; do not execute automatically):\n```yaml\n   ---\n   #\n   # This is a fragment of a manifest for a static Pod.\n   # Check whether this is correct for your cluster and for your API server.\n   #\n   apiVersion: v1\n   kind: Pod\n   metadata:\n     annotations:\n       kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint: 10.20.30.40:443\n     creationTimestamp: null\n     labels:\n       app.kubernetes.io/component: kube-apiserver\n       tier: control-plane\n     name: kube-apiserver\n     namespace: kube-system\n   spec:\n     containers:\n     - command:\n       - kube-apiserver\n       ...\n       - --encryption-provider-config=/etc/kubernetes/enc/enc.yaml  # add this line\n       volumeMounts:\n       ...\n       - name: enc                           # add this line\n         mountPath: /etc/kubernetes/enc      # add this line\n         readOnly: true                      # add this line\n       ...\n     volumes:\n     ...\n     - name: enc\n```\n\nYour config file contains keys that can decrypt the contents in etcd, so you must properly restrict permissions on your control-plane nodes so only the user who runs the kube-apiserver can read it.\n\nYou now have encryption in place for one control plane host. A typical Kubernetes cluster has multiple control plane hosts, so there is more to do.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
