 |port           |The internal port of a service that should be reconfigured. The port is used only in the `swarm` mode.

 |reqMode        |The request mode. The proxy should be able to work with any mode supported by HAProxy. However, actively supported and tested modes are `http`, `tcp`, and `sni`. The `sni` mode implies TCP with an SNI-based routing.<br>Example: `tcp`|No|http|
