    ```bash
    kubectl apply -f sleep.yaml
    ```

    Otherwise manually inject the sidecars before applying:

    ```bash
    kubectl apply -f <(istioctl kube-inject -f sleep.yaml)
    ```

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.

1. Start the `tcp-echo-server` service inside the Istio service mesh:

    ```console
    $ kubectl apply -f <(istioctl kube-inject -f tcp-echo.yaml)
    service/tcp-echo created
    deployment.apps/tcp-echo created
    ```

1. Test by running the `nc` command from a `busybox` container from within the cluster.

    ```console
    $ kubectl run -i --rm --restart=Never dummy --image=busybox -- sh -c "echo world | nc tcp-echo 9000"
