You can specify a `URL` or `-` (dash) to take data directly from `STDIN`. The

containing a fileystem or to an individual file on the Docker host. If you

specify an archive, Docker untars it in the container relative to the `/`

(root). If you specify an individual file, you must specify the full path within

the host. To import from a remote location, specify a `URI` that begins with the

`http://` or `https://` protocol.
