[erlang-questions] erlang:open_port/2 return eaddrinuse while running with docker, in open network mode.

[18年梦醒]

I use netlink(https://github.com/Feuerlabs/netlink) in my docker container,
which use erlang:open_port/2. It works fine on my linux host, but something
goes wrong in the docker container with docker open network.
I build a simple project in the github,
https://github.com/getong/netlink_docker , you can check it out.
The things goes wrong when the second container starts with the same image.
As https://github.com/getong/netlink_docker#error-message show:

                 {failed_to_start_child,netlink,

                         [{erlang,open_port,
                              [{spawn_driver,"netlink_drv 0"},[binary]],
                              []},
