Question

我使用ansible通过AWS或其他云供应商供应多个实例。这是通过python API ansible提供完成的。

如果按顺序运行Playbook，则可以正常运行。我的意思是顺序执行，一次执行一个，只有前一个完成后才转到下一个。

但是我想以异步形式执行此操作。我想同时执行几本剧本。同时创建多个实例。

尝试同时运行至少2或3时，它崩溃并显示以下错误：

File "/home/usr/proj/ansible.py", line 18, in __init__
        self.inventory = InventoryManager(loader=self.loader, sources='/etc/ansible/hosts')
      File "/home/usr/proj/venv/lib/python3.6/site-packages/ansible/inventory/manager.py", line 146, in __init__
        self.parse_sources(cache=True)
      File "/home/usr/proj/venv/lib/python3.6/site-packages/ansible/inventory/manager.py", line 207, in parse_sources
        parse = self.parse_source(source, cache=cache)
      File "/home/usr/proj/venv/lib/python3.6/site-packages/ansible/inventory/manager.py", line 253, in parse_source
        for plugin in self._fetch_inventory_plugins():
      File "/home/user/proj/venv/lib/python3.6/site-packages/ansible/inventory/manager.py", line 186, in _fetch_inventory_plugins
        plugin = inventory_loader.get(name)
      File "/home/usr/proj/venv/lib/python3.6/site-packages/ansible/plugins/loader.py", line 562, in get
        obj = getattr(self._module_cache[path], self.class_name)
    AttributeError: module 'ansible.plugins.inventory.script' has no attribute 'InventoryModule'

出现的其他错误是跳过了多个插件，但不确定其是否与前一个插件有关。巨大列表中的一个小例子：

[警告]：正在跳过插件（/home/usr/venv/lib/python3.6/site- 包/ansible/plugins/connection/buildah.py）无效：模块 'ansible.plugins.connection./home/usr/venv/lib/python3.6/site- 包/ ansible /插件/连接/ buildah'没有属性 “连接”

我的应用中声明库存的代码为：

def __init__(self):
    self.loader = DataLoader()
    self.inventory = InventoryManager(loader=self.loader, sources='/etc/ansible/hosts')
    self.variable_manager = VariableManager(loader=self.loader, inventory=self.inventory)

def run_playbook(self, playbook_path: str, playbook_name: str, extra_vars: dict = None, callback=None):
     variable_manager = VariableManager(loader=self.loader, inventory=self.inventory)
    password = open("pass", "r").read()
    variable_manager._extra_vars = {"ansible_sudo_pass": password}
    variable_manager._extra_vars = {**variable_manager.extra_vars, **extra_vars}
    playbook = playbook_path + playbook_name
    if not os.path.exists(playbook_path):
        print('[INFO] The playbook does not exist')
        sys.exit()

    # List Of Obligatory Flags To Pass When Running The Playbook
    context.CLIARGS = ImmutableDict(listtags=False,
                                    listtasks=False,
                                    listhosts=False,
                                    syntax=False,
                                    start_at_task=None,
                                    connection='ssh',
                                    module_path=None,
                                    forks=100,
                                    remote_user='root',
                                    private_key_file=None,
                                    ssh_common_args='-o StrictHostKeyChecking=no',
                                    ssh_extra_args='-o StrictHostKeyChecking=no',
                                    sftp_extra_args=None,
                                    scp_extra_args=None,
                                    become=True,
                                    become_method='sudo',
                                    become_user='root',
                                    verbosity=5,
                                    check=False,
                                    diff=False,
                                    force_valid_group_names='never')

    pbex = PlaybookExecutor(playbooks=[playbook],
                            inventory=self.inventory,
                            variable_manager=variable_manager,
                            loader=self.loader,
                            passwords={})
    pbex._tqm._stdout_callback = callback

    return pbex.run()

尝试了两个source ='localhost'和主机清单的直接路径

Ansble版本是2.8，操作系统是Ubuntu 18

我使用的代码只有一段时间，线程调用了一个其他端点，这将触发执行剧本，这意味着上面的代码：

i = 0
while i <= 2:
    x = threading.Thread(target=thread_func, args=(str(i),))
    x.start()
    i += 1

异步使用时发生Ansible失败
