python docker-py模块

官方文档https://docker-py.readthedocs.io/en/stable/

1.安装docker 模块

若是不指定版本，默认安装最新的，若不匹配会报如下错误（解决方法为在定义client时可指定client的版本）

docker.errors.APIError: 400 Client Error: Bad Request ("client is newer than server (client API version: 1.26, server API version: 1.24)") 

pip install docker -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

2.最简单测试

>>> import tab
>>> import docker
>>> client = docker.from_env()
>>> client.containers.run("ubuntu","echo hello world")
'hello world\n'

　在主机上查看

[root@centos7 ~]# docker ps -a
