                  to a single container port. For example,
                  ``{'1111/tcp': [1234, 4567]}``.

                Incompatible with ``host`` network mode.

                - ``bind`` The path to mount the volume inside the container
                - ``mode`` Either ``rw`` to mount the volume read/write, or

            The container logs, either ``STDOUT``, ``STDERR``, or both,
            depending on the value of the ``stdout`` and ``stderr`` arguments.

            ``STDOUT`` and ``STDERR`` may be read only if either ``json-file``
            or ``journald`` logging driver used. Thus, if you are using none of
            these drivers, a ``None`` object is returned instead. See the
            `Engine API documentation
            <https://docs.docker.com/engine/api/v1.30/#operation/ContainerLogs/>`_
            for full details.

            If ``detach`` is ``True``, a :py:class:`Container` object is
            returned instead.

        Raises:
            :py:class:`docker.errors.ContainerError`
                If the container exits with a non-zero exit code and
