Hi, 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"); > config.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? Best, Andrea
