云形成：进入终止状态时环境无法启动

Question

我正在建立一个有弹性的beantalk环境。运行模板时出现上述错误。我添加了IAM角色，使EC2可以完全访问云形成

 Resources:
  TestApp:
    Type: 'AWS::ElasticBeanstalk::Application'
    Properties: {}
    Metadata:
      'AWS::CloudFormation::Designer':
        id: 53bb2af6-3a68-487a-8048-34f111147171

  EBE1RNK0:
    Type: 'AWS::ElasticBeanstalk::Environment'
    Properties:
      ApplicationName: !Ref TestApp
      Description: AWS Elastic Beanstalk Environment running Node Sample Application
      EnvironmentName: NodejsEnvironment
      SolutionStackName: 64bit Amazon Linux 2 v5.0.1 running Node.js 12
      OptionSettings:

          OptionName: InstanceType
          Value: t1.micro

查看屏幕快照，尝试访问S3后失败了-令人怀疑。 AWS Docs说beantalk需要访问S3，Xray和CloudWatch Logs，并提供以下示例策略。您的角色是否包含这些权限？

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "BucketAccess",
      "Action": [
        "s3:Get*",
        "s3:List*",
        "s3:PutObject"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:s3:::elasticbeanstalk-*",
        "arn:aws:s3:::elasticbeanstalk-*/*"
      ]
    },
    {
      "Sid": "XRayAccess",
      "Action": [
        "xray:PutTraceSegments",
        "xray:PutTelemetryRecords"
      ],
      "Effect": "Allow",
      "Resource": "*"
    },
    {
      "Sid": "CloudWatchLogsAccess",
      "Action": [
        "logs:PutLogEvents",
        "logs:CreateLogStream",
        "logs:DescribeLogStreams",
        "logs:DescribeLogGroups"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:logs:*:*:log-group:/aws/elasticbeanstalk*"
      ]
    }
  ]
}

已解决：我错过了添加实例配置文件的操作，因为这将使我能够在实例开始运行时将信息传递给EC2。

这应该在您的选项设置下方。显示如下。

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