# TCP Echo Service

This sample runs [TCP Echo Server](src/) as an Istio service. TCP Echo Server
allows you to connect to it over TCP and echoes back data sent to it along with
a preconfigured prefix.

## Usage

To run the TCP Echo Service sample:

1. Install Istio by following the [istio install instructions](https://istio.io/docs/setup/kubernetes/quick-start.html).

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