Primary-remote on the same network

In primary-remote on the same network cluster, the services can access other inter-cluster services because they are on the same network. That means we don’t need an east-west gateway for inter-cluster communication between services. We will make cluster1 the primary cluster and cluster2 the remote cluster. We still need an east-west gateway to proxy istiod services. All control plane-related traffic from cluster 2 to cluster 1 will traverse via the east-west gateway.

Here, we will make use of the infrastructure we set up in the previous section, Primary-remote on multi-network, but if you want, you can also create a separate infrastructure.

Let’s get started!

1. If you are using the Kubernetes cluster from the previous section, you will need to first uninstall Istio on the remote cluster using the following code block:

   $ istioctl...
