Create a cluster
Most of the Kubernetes installation methods out there do not get you a cluster with Network Policies feature. You manually need to install and configure a Network Policy provider such as Weave Net or Calico.
Google Kubernetes Engine (GKE) easily lets you get a Kubernetes cluster with Network Policies feature. You do not need to install a network policy provider yourself, as GKE configures Calico as the networking provider for you. (This feature is generally available as of GKE v1.10.)
To create a GKE cluster named
np with Network Policy feature enabled, run:
gcloud beta container clusters create np \ --enable-network-policy \ --zone us-central1-b
This will create a 3-node Kubernetes cluster on Kubernetes Engine and turn on the Network Policy feature.
Once you complete this tutorial, you can delete the cluster by running:
gcloud container clusters delete -q --zone us-central1-b np
