Optional Parameters:
- `local_port` (string) - The port on which to
attempt to listen for SSH connections. This value is a starting point.
The provisioner will attempt listen for SSH connections on the first
available of ten ports, starting at `local_port`. The default value is 2200.
- `local_port` (string) - The port on which to attempt to listen for SSH
connections. This value is a starting point. The provisioner will attempt
listen for SSH connections on the first available of ten ports, starting at
`local_port`. When `local_port` is missing or empty, ansible-provisioner will
listen on a system-chosen port.
- `sftp_command` (string) - The command to run on the machine to handle the
SFTP protocol that Ansible will use to transfer files. The command should
