我是使用 AWS 的初学者。
我只想定期自动停止和启动几个 EC2 实例（不重启）。
有什么推荐的方法吗？
Amazon 最近（2018 年 2 月）发布了 EC2 instance scheduler 工具：
AWS Instance Scheduler 是一个简单的 AWS 提供的解决方案，它 使客户能够轻松配置自定义启动和停止时间表 用于他们的 Amazon Elastic Compute Cloud (Amazon EC2) 和 Amazon 关系数据库服务 (Amazon RDS) 实例。解决办法是 易于部署，有助于降低两者的运营成本 开发和生产环境。使用此服务的客户 在正常工作时间运行实例的解决方案最多可节省 与每天 24 小时运行这些实例相比，减少了 70%。
我在 15 分钟内在我的帐户中启动并运行了它；使用起来非常简单，而且几乎免费。

AWS 有一个很好的文档，解释了如何使用 Lambda 和 Cloudwatch 事件来实现这一点。你可以参考它 - https://aws.amazon.com/premiumsupport/knowledge-center/start-stop-lambda-cloudwatch/
这个解决方案可以修改为动态获取EC2列表，或者对一组可以根据特定标签识别的实例进行操作。
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。

另一种选择是使用

以下bash脚本是
stop-ec2.sh/home/centos/cron-scripts/(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
sh /home/centos/cron-scripts/stop-ec2.shaws 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然后在
crontab -e30 14 * * * sh /home/centos/cron-scripts/stop-ec2.sh >> /tmp/stop这会将输出记录到
/tmp/stop30 14 * * *https://crontab.guru/Lambda 脚本停止实例：
import json
import boto3
# Enter the region your instances are in. Include only the region without specifying Availability Zone; e.g., 'us-east-1'
region = 'us-east-1'
def lambda_handler(event, context):
ec2 = boto3.client('ec2', region_name=region)
filter = [{'Name': 'tag:Name', 'Values': ['****-env']}] //give instance name here in place of ****-env
instances = ec2.describe_instances(Filters=filter)
#ec2.stop_instances(InstanceIds=instances)
stop_instance = instances.get('Reservations')[0].get('Instances')[0].get('InstanceId')
stop_instances = []
stop_instances.append(stop_instance)
ec2.stop_instances(InstanceIds=stop_instances)
启动实例的Lambda脚本：
import json
import boto3
# Enter the region your instances are in. Include only the region without specifying Availability Zone; e.g., 'us-east-1'
region = 'us-east-1'
def lambda_handler(event, context):
ec2 = boto3.client('ec2', region_name=region)
filter = [{'Name': 'tag:Name', 'Values': ['****-env']}]
instances = ec2.describe_instances(Filters=filter)
#ec2.stop_instances(InstanceIds=instances)
start_instance = instances.get('Reservations')[0].get('Instances')[0].get('InstanceId')
start_instances = []
start_instances.append(start_instance)
ec2.start_instances(InstanceIds=start_instances)
ASG 调度程序是管理 EC2 实例的最佳和最简单的选项，如果您正在使用 ASG。如果不使用 ASG，那么您可以使用 AWS 实例调度程序 CF 解决方案或带有 cloudwatch Cron 事件的 lambda。
您现在可以使用 EventScheduler 并且现在已经全部涵盖了
首先创建一个 iAM 策略并在其中添加以下 json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "ec2Stop",
"Effect": "Allow",
"Action": "ec2:StopInstances",
"Resource": "*"
}
]
}
现在创建 iAM 角色，选择自定义信任策略并在信任策略中添加以下 json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "ec2Stop",
"Effect": "Allow",
"Action": "ec2:StopInstances",
"Resource": "*"
}
]
}
现在去亚马逊事件桥，创建一个调度器并指定调度器细节，你可以使用cron进行循环。然后在选择目标中选择所有 Apis 并搜索 ec2。然后搜索 stopInstances API。选择它并添加您的实例 ID。最后将角色附加到它并繁荣它全部完成以自动停止实例
同样以下是启动实例的策略其余流程保持不变
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "EC2Start",
"Effect": "Allow",
"Action": "ec2:StartInstances",
"Resource": "*"
}
]
}
