Cannot receive UDP in docker container

Coming from https://stackoverflow.com/questions/63328454/howto-test-if-container-receives-udp:

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

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.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
