销毁通过 Serverless 创建的资源而不销毁 Lambda 端点

我在 serverless.yml 文件中定义了以下资源。为我所有不同的发展阶段创建资源非常有用。

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: RANGE
        ProvisionedThroughput:
            ReadCapacityUnits: ${self:custom.dynamoDbCapacityUnits.${self:custom.stage}}
            WriteCapacityUnits: ${self:custom.dynamoDbCapacityUnits.${self:custom.stage}}

问题是...如果我这样做sls remove在删除数据库的同时，它还删除了其他所有内容，包括 lambda 函数及其 api 网关端点，因为我为它们明确设置了策略，所以我需要保留这些端点。如何告诉无服务器我只想删除数据库或 S3 或其他任何内容而不删除其余部分？

我尝试过的事情：

我在 AWS 上手动删除，但如果您执行此操作并执行 sls 部署，它不会再次创建数据库！所以不确定最好的方法来做到这一点......

The 无服务器框架文档 https://serverless.com/framework/docs/providers/aws/cli-reference/remove/说以下关于sls remove:

The sls remove命令将删除已部署的服务，定义在 您当前的工作目录，来自提供商。

So sls remove这不是要走的路。只需删除visitsTable资源来自你的serverless.yaml并运行sls deploy再次。无服务器框架在底层使用 AWS CloudFormation。所以手动删除东西并不是一个好主意。请记住：作为 AWS CloudFormation 堆栈一部分创建的资源必须通过堆栈更新进行管理和修改。也许这是一本很好的读物：https://virtualbonzo.com/2017/12/11/did-you-manually-delete-a-resource-created-by-aws-cloudformation/ https://virtualbonzo.com/2017/12/11/did-you-manually-delete-a-resource-created-by-aws-cloudformation/
