1.准备镜像：
1007 docker run -itd --name client2 ff37bc5ab732
1008 docker run -itd --name client ff37bc5ab732
1009 docker run -itd --name client1 ff37bc5ab732
1010 docker run -itd --name ansible ff37bc5ab732
1011 docker exec -it ansible /bin/bash
2.容器ansible安装：
yum --enablerepo=epel -y install ansible openssh-clients
## db-[99:101]-node.example.com
# write clients you manage
172.17.0.2
# possible to group
# define any group name you like
[target_servers]
# write clients to be grouped
172.17.0.2
172.17.0.3
172.17.0.4
172.17.0.5
3.客户端安装SSH-Agent.：简单两步完成：
ansible：
ssh-keygen -t rsa
ssh 172.17.0.5 mkdir -p .ssh
cat .ssh/id_rsa.pub | ssh 172.17.0.5 ‘cat >> .ssh/authorized_keys‘
ssh 172.17.0.5测试一下，秒过：
4.ansible安装成功：
[root@784390b5dd19 /]# ansible target_servers -m ping

"changed": false,
"ping": "pong"
}
