使用CloudFormation模板创建EC2实例状态检查失败

Question

我在us-east-1中使用下面的模板创建了一个CloudFormation堆栈和 ap-south-1 地区

AWSTemplateFormatVersion: "2010-09-09"
Description: Template for node-aws-ec2-github-actions tutorial
Resources:
  InstanceSecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: Sample Security Group
      SecurityGroupIngress:
      - IpProtocol: tcp
        FromPort: 80
        ToPort: 80
        CidrIp: 0.0.0.0/0
      - IpProtocol: tcp
        FromPort: 443
        ToPort: 443
        CidrIp: 0.0.0.0/0
      - IpProtocol: tcp
        FromPort: 22
        ToPort: 22
        CidrIp: 0.0.0.0/0
  EC2Instance: 
    Type: "AWS::EC2::Instance"
    Properties: 
      ImageId: "ami-0d2986f2e8c0f7d01" #Another comment -- This is a Linux AMI
      InstanceType: t2.micro
      KeyName: node-ec2-github-actions-key
      SecurityGroups:
      - Ref: InstanceSecurityGroup
      BlockDeviceMappings:
      - DeviceName: /dev/sda1
        Ebs:
          VolumeSize: 8
          DeleteOnTermination: true
      Tags:
        - Key: Name
          Value: Node-Ec2-Github-Actions
  EIP:
      Type: AWS::EC2::EIP
      Properties:
        InstanceId: !Ref EC2Instance
Outputs:
  InstanceId:
    Description: InstanceId of the newly created EC2 instance
    Value:
      Ref: EC2Instance
  PublicIP:
    Description: Elastic IP 
    Value:
      Ref: EIP

Stack执行成功，所有资源创建完成。但不幸的是，一旦EC2状态检查初始化，实例状态检查失败，我无法使用SSH访问实例。

我已经尝试通过相同的IAM用户手动创建一个实例，并且工作完美。

这些是我附加到IAM用户的策略。

提前感谢你的帮助。祝你过得愉快

回答我自己的问题。问题出在EBS块存储设备名称上。对于这里指定的Amazon Linux AMI，设备名称应该是/dev/xvda/

BlockDeviceMappings:
   - DeviceName: /dev/xvda
     Ebs:
       VolumeSize: 8
       DeleteOnTermination: true

谢谢你的帮助
