A federated service creates a corresponding service in the federation's member clusters.

For example, to create a federated NGINX service (assuming you have the service configuration in nginx.yaml), type the following:

> kubectl --context=federation-cluster create -f nginx.yaml 

You can verify a service was created in each cluster (for example, in cluster-2):

> kubectl --context=cluster-2 get services nginx
NAME      CLUSTER-IP     EXTERNAL-IP      PORT(S)   AGE
nginx     10.63.250.98   104.199.136.89   80/TCP    9m 

All the created services in all the clusters will share the same namespace and service name, which makes sense since they are a single logical service.

The status of your federated service will automatically reflect the real-time ...
