--publish, -p=[[ip:][hostPort]:]containerPort[/protocol]
Publish a container's port, or range of ports,<<| within this pod>> to the host.
Both hostPort and containerPort can be specified as a range of ports. When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range.
If host IP is set to 0.0.0.0 or not set at all, the port is bound on all IPs on the host.
By default, Podman publishes TCP ports. 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 is randomly assigned a port on the host.
Use podman port to see the actual mapping: podman port $CONTAINER $CONTAINERPORT.
Note that the network drivers macvlan and ipvlan do not support port forwarding,
therefore this option will have no effect on such networks.
