docker port
HOST:CONTAINER
docker expose port
docker run -p [external]:[Internal]
#example (will open in localhost:8080 to container port 80)
docker run -p 8080:80
dockerfile expose udp port
sudo docker run -p 53160:53160 \
-p 53160:53160/udp -p 58846:58846 \
-p 8112:8112 -t -i aostanin/deluge /start.sh
docker run all port mapping
docker run --network host
When running using --network host there is no need to map the ports.
All the docker container ports will be available since the network host mode
makes the container use the host's network stack.
