1. Start some other services, for example, the [Bookinfo sample](https://istio.io/docs/examples/bookinfo/).

    Now you can `kubectl exec` into the sleep service to experiment with Istio networking.
    For example, the following commands can be used to call the Bookinfo `ratings` service:

    ```bash

			gateways: []*gateway.Gateway{
				makeGateway("bookinfo", "default", false, true),
				makeGateway("bookinfo-invalid", "fake", true, false),
				makeGateway(constants.DefaultNamespaceWaypoint, "default", false, true),
				makeGateway("bookinfo-valid", "bookinfo", true, true),
				makeGateway("no-name-convention", "default", true, true),
				makeGatewayWithRevision("bookinfo-rev", "bookinfo", true, true, "rev1"),
			},
