The `container-dir` must always be an absolute path such as `/src/docs`.
The `host-dir` can either be an absolute path or a `name` value. If you
supply an absolute path for the `host-dir`, Docker bind-mounts to the path

A `name` value must start with start with an alphanumeric character,
followed by `a-z0-9`, `_` (underscore), `.` (period) or `-` (hyphen).
An absolute path starts with a `/` (forward slash).
