Access to devices on the host

If you need to directly expose some host devices to a container, you can use the devices parameter in the host_config param in Client.create_container as shown below:

cli.create_container(
    'busybox', 'true', host_config=cli.create_host_config(devices=[
        '/dev/sda:/dev/xvda:rwm'
    ])
)

Each string is a single mapping using the colon (':') as the separator. So the above example essentially allow the container to have read write permissions to access the host's /dev/sda via a node named /dev/xvda in the container. The devices parameter is a list to allow multiple devices to be mapped.
