如何在Ansible playbook api中设置“--limit”选项

提问于

我正在使用Ansible 2.4.2.0编写python脚本来运行ansible playbook .
据我所知，有一个选项"--limit"，它可以限制特定主机上的ansible游戏 .

例如：
这是/ etc / ansible / hosts
[测试]
192.168.0.1
192.168.0.2

cmd下面只允许ansible在192.168.0.1上执行test.yml
ansible-playbook test.yml --limit = "192.168.0.1"

我想知道如何在ansible playbook api中设置选项来做同样的事情 .
我尝试在选项中添加"limit='192.168.0.1"，但它不起作用 .

下面是我使用的python脚本 .

from collections import namedtuple  
from ansible.parsing.dataloader import DataLoader  
from ansible.vars.manager import VariableManager  
from ansible.inventory.manager import InventoryManager  
from ansible.executor.playbook_executor import PlaybookExecutor  

loader = DataLoader()  
inventory = InventoryManager(loader=loader, sources=['/etc/ansible/hosts'])  
variable_manager = VariableManager(loader=loader, inventory=inventory)  

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

options = Options(listtags=None, listtasks=None, listhosts=None, syntax=None, connection='smart', module_path=None, forks=100, remote_user=None,  become=None, become_method='sudo', become_user='root', verbosity=None, check=False, diff=False, ask_sudo_pass=None, limit='192.168.0.1')  

passwords = {}

pbex = PlaybookExecutor(playbooks=['/home/test.yml'], inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=passwords)  

pbex.run()
ansible

    Ansible是开源的，因此您可以随时查看现有代码 .

    在ansible-playbook CLI中是here：

    inventory.subset(self.options.subset)
    if len(inventory.list_hosts()) == 0 and no_hosts is False:
        # Invalid limit
        raise AnsibleError("Specified --limit does not match any hosts")

    在你的情况下： inventory.subset('192.168.0.1')
