docker开发之pyudev模块用法

一、实现功能：获取docker_id

#docker数据源：

[root@docker scripts]# docker ps -a

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                         PORTS               NAMES

#获取docker_id

[root@docker scripts]# cat dc_mgmt.py

#!/usr/bin/env python

# -*- coding:utf-8 -*-

#Author: nulige

import os

import re

DC_list = []

p=os.popen('docker ps -a').read()

dock_list=re.findall(r'\s\w{12}\s',p)

for i in dock_list:

    DC_list.append(i.strip())

print(DC_list)

#执行结果

[root@docker scripts]# python3 dc_mgmt.py

#获取bus号（备注：用到pyudev模块，去获取bus号）
