实例学习ansible系列（12）常用模块之docker

知识点：ansible使用docker可以对其进行管理。基本接近docker-compose对docker的使用支持，非常接近。诸如从port的设定到volume_from都支持，但是需要docker-py0.3.0 以上的支持。

使用前提条件

需要使用docker的module的管理对象节点需要满足如下前提

Package	所需版本
python	2.6 以上
docker-py	0.3.0 以上
docker server	0.10.0 以上

安装docker-py

一般python等基本上无需意识，一般安装了docker-py本模块就能支持。

安装步骤
[root@host32 ~]# yum -y python-pip
[root@host31 ~]# yum -y install python-pip
[root@host31 ~]# pip install docker-py

使用docker模块启动container

事前确认

[root@host31 ~]# ansible host32 -m shell -a "docker images && docker ps -a"
