   `nc` on MacOS does not allow use of both `-l` and `-p`. Ubuntu seems fine either with or without `-p`. What variant of `nc` is Flink's Docker image using? Is this [BusyBox](https://busybox.net/downloads/BusyBox.html#nc)? Rather than change the listed command, we may want to include a note that some variants of `nc` require the additional flag.
