是的，您可以使用AWS Lambda做到这一点。您可以在Cloudwatch中选择触发器，该触发器在UTC的Cron表达式上运行。
这是一个相关链接https://aws.amazon.com/premiumsupport/knowledge-center/start-stop-lambda-cloudwatch/
另一种方法是使用awscli它可以从pip，apt-get，yum或brew，然后运行aws configure与您的凭据从IAM导出并执行以下bash脚本，以停止已标有EC2 Name: Appname和Value: Appname Prod。您可以使用awscli标记实例或从AWS控制台手动标记实例。aws ec2 stop-instances将停止实例，jq并用于过滤json查询并使用中的标记获取正确的实例ID aws ec2 describe-instances。
要验证是否aws configure成功并返回json输出aws ec2 describe-instances，请在输出中找到您正在运行的实例ID。这是示例输出

下面的bash脚本是stop-ec2.sh在/home/centos/cron-scripts/其灵感来自这个职位的SO
(instance=$(aws ec2 describe-instances | jq '.Reservations[].Instances | select(.[].Tags[].Value | startswith("Appname Prod") ) | select(.[].Tags[].Key == "Appname") | {InstanceId: .[].InstanceId, PublicDnsName: .[].PublicDnsName, State: .[].State, LaunchTime: .[].LaunchTime, Tags: .[].Tags} | [.]' | jq -r .[].InstanceId) && aws ec2 stop-instances --instance-ids ${instance} )
使用运行文件，sh /home/centos/cron-scripts/stop-ec2.sh并验证EC2实例是否已停止。要调试运行aws ec2 describe-instances | jq '.Reservations[].Instances | select(.[].Tags[].Value | startswith("Appname Prod") ) | select(.[].Tags[].Key == "Appname") | {InstanceId: .[].InstanceId, PublicDnsName: .[].PublicDnsName, State: .[].State, LaunchTime: .[].LaunchTime, Tags: .[].Tags} | [.]' | jq -r .[].InstanceId并查看它是否返回已标记的正确实例ID。
然后可以在crontab -e下面的行中添加
30 14 * * * sh /home/centos/cron-scripts/stop-ec2.sh >> /tmp/stop
这会将输出记录到/tmp/stop。30 14 * * *您可以检入的是UTC cron表达式https://crontab.guru/。同样，替换为aws ec2 start-instances可以启动实例。
