        """
        Creates a container. Parameters are similar to those for the ``docker
        run`` command except it doesn't support the attach options (``-a``).

        The arguments that are passed directly to this function are
        host-independent configuration options. Host-specific configuration
        is passed with the `host_config` argument. You'll normally want to
        use this method in combination with the :py:meth:`create_host_config`
        method to generate ``host_config``.

        **Port bindings**

        Port binding is done in two parts: first, provide a list of ports to
        open inside the container with the ``ports`` parameter, then declare
        bindings with the ``host_config`` parameter. For example:

        .. code-block:: python

            container_id = cli.create_container(
                'busybox', 'ls', ports=[1111, 2222],
                host_config=cli.create_host_config(port_bindings={
                    1111: 4567,
                    2222: None
                })
            )


        You can limit the host address on which the port will be exposed like
        such:

        .. code-block:: python

            cli.create_host_config(port_bindings={1111: ('127.0.0.1', 4567)})

        Or without host port assignment:

        .. code-block:: python

            cli.create_host_config(port_bindings={1111: ('127.0.0.1',)})

        If you wish to use UDP instead of TCP (default), you need to declare
        ports as such in both the config and host config:

        .. code-block:: python

            container_id = cli.create_container(
                'busybox', 'ls', ports=[(1111, 'udp'), 2222],
                host_config=cli.create_host_config(port_bindings={
                    '1111/udp': 4567, 2222: None
                })
            )

        To bind multiple host ports to a single container port, use the
        following syntax:

        .. code-block:: python

            cli.create_host_config(port_bindings={
                1111: [1234, 4567]
            })

        You can also bind multiple IPs to a single container port:

        .. code-block:: python

            cli.create_host_config(port_bindings={
                1111: [
                    ('192.168.0.100', 1234),
                    ('192.168.0.101', 1234)
                ]
            })

        **Using volumes**

        Volume declaration is done in two parts. Provide a list of
        paths to use as mountpoints inside the container with the
        ``volumes`` parameter, and declare mappings from paths on the host
        in the ``host_config`` section.

        .. code-block:: python

            container_id = cli.create_container(
                'busybox', 'ls', volumes=['/mnt/vol1', '/mnt/vol2'],
                host_config=cli.create_host_config(binds={
                    '/home/user1/': {
                        'bind': '/mnt/vol2',
                        'mode': 'rw',
                    },
                    '/var/www': {
                        'bind': '/mnt/vol1',
                        'mode': 'ro',
                    }
                })
            )

        You can alternatively specify binds as a list. This code is equivalent
        to the example above:

        .. code-block:: python

            container_id = cli.create_container(
                'busybox', 'ls', volumes=['/mnt/vol1', '/mnt/vol2'],
                host_config=cli.create_host_config(binds=[
                    '/home/user1/:/mnt/vol2',
                    '/var/www:/mnt/vol1:ro',
                ])
            )

        **Networking**

        You can specify networks to connect the container to by using the
        ``networking_config`` parameter. At the time of creation, you can
        only connect a container to a single networking, but you
        can create more connections by using
        :py:meth:`~connect_container_to_network`.

        For example:

        .. code-block:: python

            networking_config = docker_client.create_networking_config({
                'network1': docker_client.create_endpoint_config(
                    ipv4_address='172.28.0.124',
                    aliases=['foo', 'bar'],
                    links=['container2']
                )
            })

            ctnr = docker_client.create_container(
                img, command, networking_config=networking_config
            )

                (e.g. ``SIGINT``).

                variables will be set in the container being created.
