ansible 1.4.3
1、查看docker已有镜像

REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
ubuntu 3.0 6cee55276528 9 weeks ago 369.8 MB
centos5 3.0 e08d23b09189 9 weeks ago 840.9 MB
centos6 3.0 e94a3b24a19b 9 weeks ago 415.9 MB
可以看到有3个镜像，1个是ubuntu，1个centos5，1个centos6.我这里打算使用centos6来弄。
2、加载新容器

09:31:01 # timedocker inspect $(docker run -d -p 22 -p 80:80 --name="smokeping" centos6:3.0 /usr/sbin/sshd -D)|grep -i address|awk -F '"' '{print $4}'
172.17.0.5
real 0m4.737s
user 0m0.038s
sys 0m0.054s
可以看到4秒就加载新容器完成，并且镜像为centos6系统，容器名为smokeping，开启了ssh服务，并且暴漏了22与80端口。
下面在从后端看看本机都运行了哪些容器

09:34:06 # cat smokeping_install/vars/main.yml
smokeping_dir: /usr/local/smokeping
smokeping_version: 2.6.8
smokeping_user: admin
smokeping_passwd: '()TF%penst*&MedHU'
可以看到smokeping安装目录是/usr/local/smokeping，安装版本是2.6.8，登陆的账户是admin，登陆密码是()TF%penst*&MedHU

花费6分52秒完成，花费时间多的主要是yum安装基础库与使用epel安装smokeping依赖库。
9、安装后测试
查看smokeping
由于我做了安全认证，需要输入账户与密码，这个账户与密码就上文第3步的账户与密码
然后默认的其他网络监控（包括1、2、3线电信、移动、联通、铁通与教育网的节点监控已经做好）
如果有其他的监控需要自己来添加即可。

如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansi ... r/smokeping_install），然后放到/etc/ansible目录里，下面是内容
