TCP Echo Service
This sample runs TCP Echo Server 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.
To run the TCP Echo Service sample:
Install Istio by following the istio install instructions.
tcp-echo-serverservice inside the Istio service mesh:
$ kubectl apply -f <(istioctl kube-inject -f tcp-echo.yaml) service/tcp-echo created deployment.extensions/tcp-echo created
Test by running the
nccommand from a
busyboxcontainer from within the cluster.
$ kubectl run -i --rm --restart=Never dummy --image=busybox -- sh -c "echo world | nc tcp-echo 9000" hello world pod "dummy" deleted
As you observe, sending world on a TCP connection to the server results in the server prepending hello and echoing back with hello world.
To clean up, execute the following command:
$ kubectl delete -f tcp-echo.yaml service "tcp-echo" deleted deployment.extensions "tcp-echo" deleted
