本文介绍了一种基于Ansible 2.8版本的自动化部署方案，通过自定义接口调用和参数传递，实现对远程主机的批量管理和任务执行。重点展示了如何通过Python脚本动态创建Ansible inventory，设置变量，并自定义回调函数来处理执行结果。

前言：根据ansible2.8官方提供的接口，做了以下调整，可以加参数

例如：请求的参数是：{"fork":"5","hosts":[{"group":"aa","ip":"192.168.100.3","port":"22","vars":{"ansible_ssh_user":"root","ansible_ssh_pass":"123456"}}],"modules":"shell","args_list":"df -h"}
