在使用ansible python模块运行时,如何更改ansible的主机值?

这是我的代码,我正在为主机传递值,但它正在本地主机上执行命令。我还尝试传递硬编码的值,在输出中显示它在给定的主机上运行。 代码如下:-

def __init__(self):
    self.variable_manager = VariableManager()
    self.loader = DataLoader()
    self.inventory = Inventory(loader=self.loader, variable_manager=self.variable_manager, host_list="host")
    Options = namedtuple('Options', ['listtags', 'listtasks', 'listhosts', 'syntax', 'connection','module_path', 'forks', 'remote_user', 'private_key_file', 'ssh_common_args', 'ssh_extra_args', 'sftp_extra_args', 'scp_extra_args', 'become', 'become_method', 'become_user', 'verbosity', 'check'])
    self.options = Options(listtags=False, listtasks=False, listhosts=True, syntax=False, connection='local', module_path=None, forks=100, remote_user='ubuntu', private_key_file="/tmp/xxx-key2.pem", ssh_common_args=None, ssh_extra_args=None, sftp_extra_args=None, scp_extra_args=None, become=False, become_method=None, become_user='root', verbosity=None, check=False)

def execute_playbook(self, playbook, host, scriptname=None, command=None,
                     path=None, username=None, password=None, key=None):
    if not os.path.exists(playbook):
        print '[INFO] The playbook does not exist'
        sys.exit()

    script_path = None
    if scriptname is not None:
        script_path = os.getcwd() + '/' + scriptname
        if not os.path.exists(script_path):
            print '[INFO] The script does not exist'
            sys.exit()
    self.variable_manager.extra_vars = {'scriptname': script_path,
                        'host': host, 'command': command, 'path': path} # This can accomodate various other command line arguments.`
    passwords = {}
    if password is not None:
        self.loader.set_vault_password(password)
    play_source =  dict(
        name = "Ansible Play",
        hosts = host,
        gather_facts = 'no',
        tasks = [
            dict(action=dict(module='shell', args='sudo mkdir /tmp/test-ansible'), register='shell_out'),
            dict(action=dict(module='debug', args=dict(msg='{{shell_out.stdout}}')))
         ]
    )
    play = Play.load(play_source, self.variable_manager, self.loader)

    tqm = TaskQueueManager(
        inventory=self.inventory,
        variable_manager=self.variable_manager,
        loader=self.loader,
        options=self.options,
        passwords=passwords,
    )

    try:
        result = tqm.run(play)
    except Exception as e:
        print e, "Exception in Ansible tqm.run()"

输出为:-
