python - 按计划重启 ElasticBeanstalk 应用服务器

问题描述

我在非默认 VPC 的私有子网中使用无服务器创建了一个 lambda 函数。我想在计划的时间重新启动 elasticbeanstalk 应用程序的应用服务器。我使用了 boto3，这是参考 [https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/elasticbeanstalk.html][1]

问题是当我在本地运行该功能时，它会运行并重新启动应用程序服务器。但是当我使用 sls deploy 进行部署时，它不起作用，当我从 lambda 控制台对其进行测试时，我得到了空响应。

这是代码：

import json
from logging import log
from loguru import logger
import boto3

    from datetime import datetime
    import pytz
    
    
        def main(event, context):
            try:
                client = boto3.client("elasticbeanstalk", region_name="us-west-1")
                applications = client.describe_environments()
                current_hour = datetime.now(pytz.timezone("US/Eastern")).hour
                for env in applications["Environments"]:
                    applicationname = env["EnvironmentName"]
                    if applicationname == "xxxxx-xxx":
                        response = client.restart_app_server(
                            EnvironmentName=applicationname,
                        )
                        logger.info(response)
                        print("restarted the application")
        
                
             return {"statusCode": 200, "body": json.dumps("restarted the instance")}
       except Exception as e:
            logger.exception(e)

    if __name__ == "__main__":
        main("", "")

这里是 serverless.yml 文件：
