+To configure which services and ports will be exposed
+```
+kubectl create -f tcp-configmap-example.yaml
+```
+
+The file `tcp-configmap-example.yaml` uses a ConfigMap where the key is the external port to use and the value is
+`<namespace/service name>:<service port>`
+It is possible to use a number or the name of the port.
+
+```
+kubectl create -f rc-tcp.yaml
+```
+
+Now we can test the new service:
+```
+$ (sleep 1; echo "GET / HTTP/1.1"; echo "Host: 172.17.4.99:9000"; echo;echo;sleep 2) | telnet 172.17.4.99 9000
