amazon-web-services - 服务员ChangeSetCreateComplete失败: Waiter encountered a terminal failure state

Question

我正在学习 CloudFormation 教程，这是我的 AWS CloudFormation 模板:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: A starter AWS Lambda function.
Resources:
  helloworldpython3:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: app.lambda_handler
      Runtime: python3.6
      CodeUri: src/
      Description: A starter AWS Lambda function.
      MemorySize: 128
      Timeout: 3
      Environment:
        Variables:
          TABLE_NAME: !Ref Table
          REGION_NAME: !Ref AWS::Region
      Events:
        HelloWorldSAMAPI:
          Type: Api
          Properties:
            Path: /hello
            Method: GET
      Policies:
        - DynamoDBCrudPolicy:
            TableName: !Ref Table

Table:
  Type: AWS::Serverless::SimpleTable
  Properties:
    PrimaryKey:
      Name: greeting
      Type: String
    ProvisionedThroughput:
      ReadCapacityUnits: 1
      WriteCapacityUnits: 1

我可以使用aws cloudformation package生成最终模板。但是当我尝试使用 sam deploy 部署它时，我从 shell 中得到以下输出:

error : Waiting for changeset to be created..Error: Failed to create changeset for the stack: hello-world-sam,ex: Waiter ChangeSetCreateComplete failed: Waiter encountered aterminal failure state: For expression "Status" we matchedexpected path: "FAILED" Status: FAILED. Reason: Invalidtemplate property or properties [Table]

Answer 1

在我的例子中，cfn linter 可以使用 yaml，错误(使用 cmd 中的 aws CLI)只是

Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state:

For expression "Status" we matched expected path: "FAILED"

你应该离开检查AWS console → CloudFormation → {stack_name} → 变更集

我的错误原因在这里

Status reason

No updates are to be performed.
