To publish a UDP port instead, give +`udp` as protocol. To publish both TCP and UDP ports, set `--publish` twice, +with `tcp`, and `udp` as protocols respectively. Rootful containers can also +publish ports using the `sctp` protocol. + +Host port does not have to be specified (e.g. `podman run -p 127.0.0.1::80`). +If it is not, the container port will be randomly assigned a port on the host. + +Use **podman port** to see the actual mapping: `podman port $CONTAINER $CONTAINERPORT`. |
