Description

Seem to be unable to publish ports to the host w/ docker run. Perhaps I'm doing something wrong

        conatiner = client.containers.run(
            image='mongo:3.2.11',
            detach=True,
            name='name',
            network_mode='host',
            ports={
                '{}/tcp'.format(27017): ('127.0.0.1', 30000)
            },
            publish_all_ports=True
        )
            },
            "NetworkMode": "host",
            "PortBindings": {
                "27017/tcp": [
                    {
                        "HostIp": "127.0.0.1",
                        "HostPort": "30000"
                    }
                ]
            },
...

Research direction

Start with the containers.run() call shown in the report and reproduce it using network_mode='host', the ports mapping, and publish_all_ports=True. Compare the resulting PortBindings and NetworkSettings with the expected host-port behavior; done means the issue is fixed or the supported behavior is clearly established and covered by an appropriate test.
