+# Kata Admission controller webhook
+
+Implement a simple admission controller webhook to annotate pods with the 
+Kata runtime class.
+
+## How to build the admission controller
+
+First build the admission controller image and the associated
+Kubernetes yaml files required to instantiate the admission
+controller.
+
+```bash
+$ docker build -t katadocker/kata-webhook-example:latest .
+$ ./create_certs.sh
+```
+
+> **Note:**
+> Image needs to be published for the webhook needs to work. Alternately
+> on a single machine cluster change the `imagePullPolicy` to use the locally
+> built image.
+
+## Making Kata the default runtime using an admission controller
+
+Today in `crio.conf` `runc` is the default runtime when a user does not specify
+`runtimeClass` in the pod spec. If you want to run a cluster where Kata is used
+by default, except for workloads we know for sure will not work with Kata, use
+the [admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/#admission-webhooks)
+and sample admission controller we created by running
+
+```bash
+$ kubectl apply -f deploy/
+```
+
+The webhook mutates pods to use the kata runtime class for all pods except
+those with 
+
+* `hostNetwork: true` 
+* namespace: `rook-ceph` and `rook-ceph-system`
