错误
发生错误：sampleEnvironment - 环境在进入终止状态时无法启动。

注意
配置文件beanstalk-test-deployment已经具有 IAM 角色：

• AWSElasticBeanstalkFullAccess
• 管理员权限

您需要创建aws-elasticbeanstalk-ec2-role AWS::IAM::InstanceProfile 并在 sampleConfigurationTemplate 的 OptionSettings 中提供它：

- Namespace: aws:autoscaling:launchconfiguration
  OptionName: IamInstanceProfile
  Value: aws-elasticbeanstalk-ec2-role

该角色可以使用这些托管策略 Arn：

- arn:aws:iam::aws:policy/AWSElasticBeanstalkWebTier
- arn:aws:iam::aws:policy/AWSElasticBeanstalkWorkerTier
- arn:aws:iam::aws:policy/AWSElasticBeanstalkMulticontainerDocker

如果添加此角色没有帮助，则该错误还可能表明.ebextensions失败。我曾经通过在 ebextensions 中调用一个不存在的 KeyName 来得到这个错误。
