 ## Example: gRPC health checking on Kubernetes
 
-Kubernetes does not natively support gRPC health checking since it does not
-favor one RPC framework over another. Similarly, HTTP health probes Kubernetes
-has is not sufficient to craft a valid gRPC request. As a solution,
+Kubernetes now supports [gRPC health checking][k8s]. If your cluster is running a version of Kubernetes that supports gRPC health checking, you can use the following example to define a liveness probe for your gRPC server:
+
+```yaml
+apiVersion: v1
+kind: Pod
+metadata:
+   name: etcd-with-grpc
+spec:
+   containers:
+      - name: etcd
+        image: registry.k8s.io/etcd:3.5.1-0
+        command: [ "/usr/local/bin/etcd", "--data-dir",  "/var/lib/etcd", "--listen-client-urls", "http://0.0.0.0:2379", "--advertise-client-urls", "http://127.0.0.1:2379", "--log-level", "debug"]
+        ports:
+           - containerPort: 2379
+        livenessProbe:
+           grpc:
+              port: 2379
+           initialDelaySeconds: 10
+```
+
+For more information on how to define a gRPC liveness probe in Kubernetes, see the [Kubernetes documentation][k8s-new].
+
+However, Kubernetes if your Kubernetes version does not support gRPC health checking, you can use `grpc_health_probe` to health-check your gRPC server. As a solution, 
 `grpc_health_probe` [can be used for Kubernetes][k8s] to health-check gRPC
 servers running in the Pod.
