[FEAT] Add environment flag to set listening port.

Is this a new feature request?

• [X] I have searched the existing issues

Wanted change

Can we please add the ability to configure the listening port, it overrides the port in the config every start and for those of us who use macvlan/ipvlan's, using port mapping isn't an option and would rather just use the port explicitly.

Reason for change

because this would be useful.

Proposed code change

never mind, found the other ticket with the flag, environment var missing from dockerhub information so had not seen it.
