before-you-begin), and set `networkPolicy.enabled` to `true`. For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting the DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace: ``` kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}" ``` When using `Cilium` as a CNI in your cluster, please edit the `flavor` field to `cilium`. With NetworkPolicy enabled, traffic will be...

	The v1beta1 API used an annotation on Namespaces to activate the DefaultDeny policy for an entire Namespace. To activate default deny in the v1 API, you can create a NetworkPolicy that matches all Pods but does not allow any traffic:

    ```yaml
    kind: NetworkPolicy

	When upgrading to Kubernetes 1.7 (and a network plugin that supports
	the new NetworkPolicy v1 semantics), to ensure full behavioral
	compatibility with v1beta1:
	1. In Namespaces that previously had the "DefaultDeny" annotation,
	   you can create equivalent v1 semantics by creating a
	   NetworkPolicy that matches all pods but does not allow any
	   traffic:

	   ```yaml
           kind: NetworkPolicy
