标签:reg 配置 info for 提示 star lambda ber describe 下面是一个例子遍历所有的region查找EC2,如果状态是开机,那就关掉;或者倒过来也可以写成 如果是关机状态,就开机。 执行一下是工作的 然后我们在aws的Lambda里创建一个新的函数, 这里我已经自定义了一个role了,确保这个role可以对ec2有开机和关机的权限 IAM的权限如下所示: 拷贝函数上来 接下来 在cloudwatch里面添加一个新的rule 创建向导,这里选择schedule,这里使用 cron的表达式,注意他是GMT的时间,因此需要自己和本地时间转换一下 写好之后他会有个友好的提示界面 完成创建 回到Lambda的界面, 可以看见他的触发器多了一个CloudWatch Events 等待执行之后,可以查看日志 也可以确认EC2 服务 的确关机了 Lambda,AWS和Python的自动化管理操作 - 自动开机和关机 标签:reg 配置 info for 提示 star lambda ber describe 原文地址:https://blog.51cto.com/beanxyz/2439072import boto3
