如何使用 SAM 正确创建 Dynamodb table

Question

刚刚开始使用 AWS SAM。想使用 Lambda 和 DynamoDB 创建一个 CRUD 微服务我的 template.yaml:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: >-
  A simple backend (read/write to DynamoDB) with a RESTful API endpoint using Amazon API Gateway.
Resources:
  microservicehttpendpoint:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: index.handler
      Runtime: nodejs12.x
      CodeUri: .
      Description: >-
        A simple backend (read/write to DynamoDB) with a RESTful API endpoint using Amazon API Gateway.
      MemorySize: 512
      Timeout: 10
      Policies:
        - DynamoDBCrudPolicy:
            TableName: MyTable
      Events:
        Api1:
          Type: Api
          Properties:
            Path: /MyResource
            Method: ANY
  MyTable:
  Type: AWS::Serverless::SimpleTable
  Properties:
    PrimaryKey: name
    TableName: dynocrud-table

我希望创建三个资源：a) Lambda，b) Api 网关端点，3) DynamoDB table Lambda 和 API 网关端点正在按预期创建，但没有 DynamoDB table，也没有错误。这是 cli 输出：

为了与其他资源一起创建 DynamoDB table，我应该更改什么？

Answer 1

请确保您的 yaml 文件正确缩进。 Type: 应在资源名称下方缩进，例如

MyTable:
  Type: AWS::Serverless::SimpleTable <-- indented here
  Properties:
    PrimaryKey: name
    TableName: dynocrud-table
