使用 Python API 2.0.0.1 运行 Ansible Playbook

安塞布尔版本：2.0.0.1

我现在已经四处寻找了很多，我发现的大多数文档要么不完整，要么已弃用（这篇文章适用于1.8.4版本，即 https://stackoverflow.com/questions/27590039/running-ansible-playbook-using-python-api?newreg=7a292f45eb6c43e2a4c3be5ac30efc11)

我正在尝试通过 Python API 启动 Ansible playbook。 Ansible 的文档似乎展示了如何生成和播放任务，但没有展示如何加载和运行 playbook yml 文件。我一直在深入研究代码，试图了解如何启动它，我认为我已经取得了一些进展，但我真的遇到了困难。这是我到目前为止所拥有的：

def createcluster(region, environment, cluster):
    Options = namedtuple('Options', ['region','env', 'cluster'])

    # initialize needed objects
    variable_manager = VariableManager()
    loader = DataLoader()
    options = Options(region=region, env=environment, cluster=cluster)
    options.listhosts = False
    vault_password = getpass.getpass('Enter vault password :')
    passwords = dict(vault_pass=vault_password)

    #Getting hosts
    hostsread = open('provisioning/inventory/hosts','r')
    hosts =  hostsread.read()
    inventory = Inventory(loader=loader, variable_manager=variable_manager, host_list=hosts)
    variable_manager.set_inventory(inventory)
    #Create and load the playbook file
    playbook = Playbook(loader)
    playbook.load('provisioning/cluster.yml', variable_manager,loader)

    #Create an executor to launch the playbook ? 
    executor = None
    executor = PlaybookExecutor(playbook,inventory,variable_manager,loader,options,passwords)
    try:
        result = executor.run()
    finally:
        if executor is not None:
            executor.cleanup()

我完全不确定执行器部分，当我尝试启动代码时，我不断收到“AttributeError：'Options'对象没有属性'listhosts'”错误（很奇怪，因为它应该忽略它的缺失，我认为（第 60 行） https://github.com/ansible/ansible/blob/stable-2.0.0.1/lib/ansible/executor/playbook_executor.py)

我应该如何加载 YML 文件并通过 Python API 启动它？我是走在正确的道路上还是迷失了自己？为什么 Ansible 没有更好的文档记录？为什么 42 是 7*7 的答案？

以下是 Ansible 2 的示例：

#!/usr/bin/python2

from collections import namedtuple
from ansible.parsing.dataloader import DataLoader
from ansible.vars import VariableManager
from ansible.inventory import Inventory
from ansible.playbook import Playbook
from ansible.executor.playbook_executor import PlaybookExecutor

Options = namedtuple('Options', ['connection',  'forks', 'become', 'become_method', 'become_user', 'check', 'listhosts', 'listtasks', 'listtags', 'syntax', 'module_path'])

variable_manager = VariableManager()
loader = DataLoader()
options = Options(connection='local', forks=100, become=None, become_method=None, become_user=None, check=False, listhosts=False, listtasks=False, listtags=False, syntax=False, module_path="")
passwords = dict(vault_pass='secret')

inventory = Inventory(loader=loader, variable_manager=variable_manager, host_list='localhost')
variable_manager.set_inventory(inventory)
playbooks = ["./test.yaml"]

executor = PlaybookExecutor(
              playbooks=playbooks,
              inventory=inventory,
              variable_manager=variable_manager,
              loader=loader,
              options=options,
              passwords=passwords)

executor.run()

使用 Python 2.7.10 和 ansible 2.0.1.0 进行测试
