使用ansible批量在服務(wù)器安裝docker
注意：
1. ansible版本是2.8，其他版本也都是支持的，低版本請自行百度下，看下模塊的使用方法
2. 我修改了docker的存儲路徑，默認(rèn)是在/var/lib/docker，系統(tǒng)盤太小，所以單獨掛載了一塊數(shù)據(jù)盤，掛載到了/data，執(zhí)行腳本請確定有/data此目錄
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. 執(zhí)行腳本
ansible-playbook docker_install.yml
6. 腳本內(nèi)容：
cat /usr/local/srcipt/docker_install.yml
