Ansible版本2.6.4，記錄下ansible API使用，合入到運營系統(tǒng)，會使用到ansible批量操作服務(wù)器唉工，ansible本身就是python寫的，所以對于python來說可以直接調(diào)用汹忠，有興趣了解更多可以去官網(wǎng)看看https://docs.ansible.com/ansible/latest/index.html

來自官網(wǎng)的python api example，簡單的封裝了一下花履，就可以用了僧界！其中每一步做了什么我都做了注釋，如果還需要了解更詳細的內(nèi)容臭挽，推薦讀下官方文檔，甚至可以讀下源碼咬腕，以后有空了再研究下源碼欢峰，現(xiàn)在業(yè)務(wù)忙也沒時間搞
