Cannot receive UDP in docker container
I'm having troubles with my container receiving UDP responses. I've tried to test this and the test already fails (using OSX):
~/htdocs/evcc master 17s ❯ docker run -p 7090:7090/udp -it --rm alpine / # nc -u -l 0.0.0.0 7090
and from the host:
~/htdocs/evcc master ❯ nc -u 0.0.0.0 7090 ljkhgdkfjhg
Yet, no echo inside the container. The same works fine when both are run on the host. Same also works when e.g. using Ubuntu as image.
