kubeasz/tools/change_ip_aio.yml

# 敬告：本脚本仅作测试交流使用
# 此脚本仅用于allinone部署情况下，需要修改host ip地址使用（比如，虚机装完allinone部署，克隆或者复制分享给别人测试使用）
#
# ------- 前提 ：一个运行正常的allinone部署在虚机，关机后复制给别人使用，新虚机开机后如果需要修改IP，请执行如下步骤
# 0. 拉取最新项目代码：git pull origin master
# 1. 修改ansible hosts文件：sed -i 's/$OLD_IP/$NEW_IP/g' /etc/ansible/hosts
# 2. 配置ssh免密码登陆：ssh-copy-id $NEW_IP 按提示完成
# 3. 检查下修改是否成功，并且能够成功执行 ansible all -m ping
