SOLVED in last post…
What I want:
Write data, from inside a container, to a UDP port and be able to run host-side program to read data off this port for onward host-side processing.
What i see:
After running the container, when I execute the host-side program, I am unable to bind to the UDP port since the docker-proxy program has created a binding to the port:
socket.error: [Errno 98] Address already in use
I have confirmed this by switching the execution order of the container and host-side program, where host-side program binds to the port just fine and the ‘docker run’ command fails since it now cannot bind to the UDP port.
Dockerfile line (relevant):
Docker run (relevant):
docker run -p 8888:8888/udp
So the question is: how do I create / run a docker container such that I am transmitting data, from inside the container, across a UDP port, for reading by a program host-side?
Is this possible?
thanks in advance for any and all advice.
