    12  The `null` Packer builder is not really a builder, it just sets up an SSH connection
    13  and runs the provisioners. It can be used to debug provisioners without
    14  incurring high wait times. It does not create any kind of image or artifact.
    15  
    16  ## Basic Example
    17  
    18  Below is a fully functioning example. It doesn't do anything useful, since
    19  no provisioners are defined, but it will connect to the specified host via ssh.
    20  
    21  ```javascript
    22  {
    23    "type":     "null",
    24    "host":     "127.0.0.1",
    25    "ssh_username": "foo",
    26    "ssh_password": "bar"
    27  }
    28  ```
    29  
    30  ## Configuration Reference
    31  
    32  The null builder has no configuration parameters other than the
    33  [communicator](/docs/templates/communicator.html) settings.
