Managing Services and Ingress

The service is an abstraction method that exposes applications running in a set of pods as a network service, and ingress is used to expose HTTP and HTTPS paths from outside the cluster to inside the cluster. After creating a namespace, you can create or delete services, endpoints, ingresses, and ingress classes.

Reference

Service, Endpoint, Ingress, IngressClass The service is set to the default cluster (namespace) selected when the service is created. Even if you select other items in the list, the default cluster (namespace) setting is maintained.

To select a different cluster (namespace), click the gear button on the right side of the list. In the Cluster/Namespace Settings popup window, select the cluster and namespace you want to change and click the OK button. You can see the services created in the selected cluster/namespace.
