一、安装方式

建议使用 pip3 install ansible 的方式安装，便于导入模块

这种安装方式，配置文件不会在 /etc 下产生。

将会在下面的路径下： ``` /usr/local/lib/python3.7/site-packages/ansible/galaxy/data/container/tests
```

二、 先从官方示例入手

点击 官方示例源码 v2.8

注意：下面的所以开发，都是以 2.8 版本为例的。2.7 和 2.8 版本有一些差异： 2.7 使用了 Python 标准库里的 命名元组来初始化选项，而 2.8 是 Ansible 自己封装了一个 ImmutableDict ，之后需要和 context 结合使用的。两者不能互相兼容。 点击 2.7 官方示例
