ansible安装docker脚本

使用ansible批量在服务器安装docker

注意：

1. ansible版本是2.8，其他版本也都是支持的，低版本请自行百度下，看下模块的使用方法

2. 我修改了docker的存储路径，默认是在/var/lib/docker，系统盘太小，所以单独挂载了一块数据盘，挂载到了/data，执行脚本请确定有/data此目录

3. 使用直接修改 yourhosts即可

4. 配置范例

cat /etc/ansible/hosts

[yourhosts]

web01 ansible_host=192.168.10.30 ansible_port=22 ansible_user=root ansible_password=1qaz

web02 ansible_host=192.168.10.23 ansible_port=22 ansible_user=root ansible_password=2wsx

5. 执行脚本

ansible-playbook docker_install.yml

6. 脚本内容：

cat /usr/local/srcipt/docker_install.yml
