如何将变量设置为 ansible 清单? [英] How to set vars into ansible inventory?
问题描述
在剧本中我使用变量 {{excluded_service}}.我想从 python 运行 ansible playbook 并提供这个变量.而且我不能使用外部库存脚本来提供这个变量.我正在使用创建库存:
In playbook I'm using variable {{excluded_service}}. I want to run ansible playbook from python and provide this variable. And I can't use external inventory script to provide this variable. I am using to create inventory:
hosts = ["127.0.0.1"]
inventory=ansible.inventory.Inventory(hosts)
但我不明白在哪里可以添加变量的值?
but I don't understand where I can add value of variable?
我的代码，适用于外部库存脚本:

推荐答案
在 host_vars 文件?例如.创建一个名为 /etc/ansible/host_vars/localhost 的 YAML 文件，其中包含您想要放置的变量.
Specify the vars in a host_vars file?
E.g. create a YAML file named /etc/ansible/host_vars/localhost with the vars you wanna put there.
我还不知道如何在 Python 代码中指定它.
I don't know, yet, how to specify it in Python code itself.
--- 更新---
快速查看代码后，我认为当您通过 host_list 参数指定主机时，ansible 不支持指定主机变量.我能想到的黑客(如果你必须在 python 代码中这样做)是:
After a quick look the code, I don't think ansible supports specifying host variables when you specify hosts via host_list parameter. Hacks I can think of (if you must do this in python code) are:
- [误]使用 extra_vars 参数.
- 从您的 Python 代码编写一个清单文件(YAML 或仅打印所需 JSON 的可执行文件)，并将其路径作为参数
inventory传递.
