If I want to use docker swarm in my system, I know I must open port 2377,7946 and 4789. And I know that the port 2377 and 4789 can be changed through --listen-addr and --data-path-port, but I didn't find any option to change port 7946. What shall I do?

I did a quick research to see if it was released yet. But by the looks of some GitHub issues for instance this, it does not look like they made any progress on the topic itself. By the look of the swarm init and swarm update it does not look there would be any sign of the documentation stating there could be any config to do such a thing.

    By the looks of the already open question [Is it possible to customise the swarm port? How to do this?](https://stackoverflow.com/questions/57151496/is-it-possible-to-customize-swarm-port-if-so-how-to-do-this) it does not look like any good news as well. – matic1123 May 18 '22 at 09:11
