amazon-web-services - 已删除 Cloudformation 堆栈，由于资源已存在，现在无法重新创建新的 Cloudformation 堆栈

Question

我遇到了导致我的堆栈无法恢复的情况，我别无选择，只能将其删除。使用完全相同的模板，我继续创建了另一个同名的堆栈。

The following resource(s) failed to create: [AdminPanelCDNAccessIdentity, 
BackendLogGroup, BackendLoadBalancerSecurityGroup, AdminPanelCertificate, 
EnvironmentCertificate, AdminPanelBucket, BackendECSTaskRole, 
BackendECSTaskBitbucketAccess2RunTask, BackendLoadBalancerTargetGroup]. The 
following resource(s) failed to update: [FrontEndBucket].

我真的需要手动删除所有这些资源并从头开始重建它们吗？这似乎是一个糟糕的选择。

这是我的模板代码的示例片段

Resources:
FrontEndBucket:
Type: 'AWS::S3::Bucket'
Properties:
  BucketName: !If 
    - IsProduction
    - 'Fn::ImportValue': !Sub '${LandscapeStack}-DNSDomain'
    - 'Fn::Sub':
        - '${EnvironmentSubdomain}.${LandscapeDomain}'
        - LandscapeDomain:
            'Fn::ImportValue': !Sub '${LandscapeStack}-DNSDomain'
  AccessControl: Private
  Tags:
    - Key: landscape
      Value: !Ref Landscape
    - Key: environment
      Value: !Ref EnvironmentName
  WebsiteConfiguration:
    IndexDocument: index.html

  'AWS::CloudFormation::Designer':
    id: 53eb6c3a-767f-46fb-a719-2846f1fd6bdd
FrontEndBucketPolicy:
Type: 'AWS::S3::BucketPolicy'
Properties:
  Bucket: !Ref FrontEndBucket
  PolicyDocument:
    Statement:
      - Effect: Allow
        Action:
          - 's3:PutObject'
          - 's3:GetObject'
          - 's3:DeleteObject'
        Resource: !Sub 'arn:aws:s3:::${FrontEndBucket}/*'
        Principal:
          AWS:
            'Fn::ImportValue': !Sub '${CIResourcesStack}-BitbucketFrontEndPipelineUser'
      - Effect: Allow
        Action:
          - 's3:ListBucket'
        Resource: !Sub 'arn:aws:s3:::${FrontEndBucket}'
        Principal:
          AWS:
            'Fn::ImportValue': !Sub '${CIResourcesStack}-BitbucketFrontEndPipelineUser'
      - Effect: Allow
        Action:
          - 's3:GetObject'
        Resource: !Sub 'arn:aws:s3:::${FrontEndBucket}/*'
        Principal:
          CanonicalUser: !GetAtt FrontEndCDNAccessIdentity.S3CanonicalUserId

对此的任何帮助将不胜感激!!

您可能选择保留删除堆栈时未能删除的所有资源。 CloudFormation 不会将现有资源纳入堆栈。您需要手动删除旧堆栈创建的所有资源，然后才能部署此完全相同的堆栈。或者，您可以在再次部署之前更改资源的名称。
