Description:

def remove(name, stop=False):
    '''
    Remove the named container

    .. warning::

        This function will remove all data associated with the container. It
        will not, however, remove the btrfs subvolumes created by pulling
        container images (:mod:`nspawn.pull_raw
        <salt.modules.nspawn.pull_raw>`, :mod:`nspawn.pull_tar
        <salt.modules.nspawn.pull_tar>`, :mod:`nspawn.pull_dkr
        <salt.modules.nspawn.pull_dkr>`).

    stop : False
        If ``True``, the container will be destroyed even if it is
        running/frozen.

    CLI Examples:

    .. code-block:: bash

        salt '*' nspawn.remove foo
        salt '*' nspawn.remove foo stop=True

        raise CommandExecutionError(
            'Unable to remove container \'{0}\': {1}'.format(name, exc)
