如何在带有保险库的 Ansible v2 中运行 playbook api

Question

这是我所拥有的，我知道这可以在不加密的情况下使用，我可以运行

ansible-vault edit common.yml

和

ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass.txt

在环境中设置

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

variable_manager = VariableManager()
loader = DataLoader()

inventory = Inventory(loader=loader, variable_manager=variable_manager,  host_list='playbooks/hosts')
playbook_path = 'playbooks/' + PROJECT + '.yml'

Options = namedtuple('Options', ['connection',  'forks', 'become', 'become_method', 'become_user', 'check', 'listhosts', 'listtasks', 'listtags', 'syntax', 'module_path', 'vault_password_file'])
options = Options(connection='ssh', forks=5, become=None, become_method=None, become_user=None, check=False, listhosts=False, listtasks=False, listtags=False, syntax=False, module_path="", vault_password_file=os.environ['ANSIBLE_VAULT_PASSWORD_FILE'])

variable_manager.extra_vars = {'CAP_VERSION': CAP_VERSION, 'cluster': PROJECT + '-' + ENVIRONMENT, 'environ': ENVIRONMENT, 'rpm': rpmSource, 'VRSN': ARTI_BRANCH }

passwords = {}

pbex = PlaybookExecutor(playbooks=[playbook_path], inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=passwords)
results = pbex.run()

在 ansible 2.2.2 中（不确定其他版本，因为 API 可以经常更改）：

您可以在 python 脚本中手动设置密码，如下所示：

loader = DataLoader()
loader.set_vault_password('mypass')

或者您可以从保管库密码文件加载密码：

import os
loader = DataLoader()
with open('{}/.vault_pass.txt'.format(os.path.expanduser('~')), 'r') as file:
    loader.set_vault_password(file.read().splitlines()[0])

您可以跳过导入 os，只需输入 .vault_pass.txt 文件的绝对路径即可。

如果您确定您的 ANSIBLE_VAULT_PASSWORD_FILE 已在环境中设置：

import os
loader = DataLoader()
with open(os.environ['ANSIBLE_VAULT_PASSWORD_FILE'], 'r') as file:
    loader.set_vault_password(file.read().splitlines()[0])
