如何在使用ansible-python模块运行时更改ansible的主机值？

Question

这是我的代码，我在那里为主机传递值，但是它在localhost上执行命令。我也试过传递硬编码的值，并在输出中显示它在给定的主机上运行。这是代码： -

类定义然后，

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()"

输出是： -

PLAY [Ansible Play] *************************************************************************************************************************

TASK [command] ******************************************************************************************************************************
[WARNING]: Consider using 'become', 'become_method', and 'become_user' rather than running sudo

changed: [110.110.112.139]

TASK [debug] ********************************************************************************************************************************
ok: [110.110.112.139] => {
"msg": ""
}

但它在我的localhost中创建目录而不是“110.110.112.139”。

Answer 1

你将connection='local'设置为__init__中的选项。 这意味着Ansible无论目标主机是什么，都可以在localhost上执行任务。

不要设置它（保留默认值）或使用ssh远程执行任务。
