Command: vagrant port [name|id]
The port command displays the full list of guest ports mapped to the host machine ports:
$ vagrant port
22 (guest) => 2222 (host)
80 (guest) => 8080 (host)
In a multi-machine Vagrantfile, the name of the machine must be specified:
$ vagrant port my-machine
--guest PORT - This displays just the host port that corresponds to the
given guest port. If the guest is not forwarding that port, an error is
returned. This is useful for quick scripting, for example:
$ ssh -p $(vagrant port --guest 22)
--machine-readable - This tells Vagrant to display machine-readable output
instead of the human-friendly output. More information is available in the
machine-readable output documentation.
