问题描述
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:
错误:正在等待创建变更集.. 错误:无法为堆栈创建变更集:hello-world-sam, 例如:Water ChangeSetCreateComplete Failed: Waiter遇到了一个 终端故障状态:对于表达式“状态”,我们匹配 预期路径:“失败”状态:失败。原因:无效 模板属性或属性[表格]
解决方法
您的 YAML 格式不正确:
AWSTemplateFormatVersion: "2010-09-09"
Transform: "AWS::Serverless-2016-10-31"
Description: A starter AWS Lambda function.
Resources:
helloworldpython3:

Properties:
Handler: app.lambda_handler
Runtime: python3.6

Table
应该在 Resources
之下。使用像 cfn-python-lint
