我有 2 個模板，如下所示。我想問的是如何Sub在Transform中使用和其他變數？
添加 UserData 時，出現以下錯誤。這是關于Sub。如何根據轉換進行更改？
轉換 AWS::Include 失敗：指定的 S3 物件的內容應該是有效的 Yaml/JSON。用戶請求回滾。

uj5u.com熱心網友回復：
你不能使用!Sub. 它應該是Fn::Sub:：
Type: 'AWS::EC2::Instance'
Properties:
KeyName: test
ImageId: ami-0015a39e4b7c0966f
InstanceType:
Ref: InstanceType
SubnetId:
Fn::Select: [ 0, Ref: Subnets ]
SecurityGroupIds:
- Fn::GetAtt: [ Sec, GroupId ]
UserData:
Fn::Base64:
Fn::Sub: |
#!/bin/bash -xe
yum update -y aws-cfn-bootstrap
/opt/aws/bin/cfn-init -v --stack ${AWS::StackName} --resource LaunchConfig --configsets wordpress_install --region ${AWS::Region}
/opt/aws/bin/cfn-signal -e $? --stack ${AWS::StackName} --resource WebServerGroup --region ${AWS::Region}
