>         Environment: ```
> $ uname -a

> Flink (or some of its services) listens on three random TCP ports
> during the local[1] execution, e.g., 39951, 41009 and 42849.
> [1]: https://ci.apache.org/projects/flink/flink-docs-stable/dev/local_execution.html#local-environment
> The sockets listens on `0.0.0.0` and since I need to run some
> long-running tests on an Internet-facing machine I was wondering how
> to make them listen on `localhost` instead or if there is anything
> else I can do to improve the security in this scenario.
> Here's what I tried (with little luck):
> ```
> Configuration config = new Configuration();
> config.setString("taskmanager.host", "127.0.0.1");
> cconfig.setString("rest.bind-address", "127.0.0.1"); // OK
> config.setString("jobmanager.rpc.address", "127.0.0.1");
> StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironment(StreamExecutionEnvironment.getDefaultLocalParallelism(), config);
> ```
> Only the `rest.bind-address` configuration actually changes the
> binding address of one of those ports. Are there other parameters that
> I'm not aware of or this is not the right approach in local mode?
