--expose=port[/protocol]

Expose a port or a range of ports (e.g. --expose=3300-3310). The protocol can be tcp, udp or sctp and if not given tcp is assumed. This option matches the EXPOSE instruction for image builds and has no effect on the actual networking rules unless -P/--publish-all is used to forward to all exposed ports from random host ports. To forward specific ports from the host into the container use the -p/--publish option instead.
