Question

我正在尝试通过CloudFormation模板启动Elastic Beanstalk应用程序，但是我一直收到错误The EC2 instances failed to communicate with AWS Elastic Beanstalk, either because of configuration problems with the VPC or a failed EC2 instance. Check your VPC configuration and try launching the environment again.，我已经尝试了所有可以找到的解决方案，但似乎没有任何效果。另外，我无法进入已启动的EC2实例，因此我必须假定它们是相关的。与无法通过公共互联网访问有关吗？我是Elastic Beanstalk（和EC2）的新手，所以感谢您的帮助。这是我的CloudFormation模板的相关部分：

Answer 1

您可以将模板分为两个

运行VPC模板
启动t2.micro并测试连接性
然后运行Elasticbeanstalk模板

似乎您缺少到Internet（公共端点）的路由

还请禁用回滚并排除故障。很有可能是其连接专用子网和elasticbeanstalk服务或s3端点。
