如何为我的lambda功能添加SQS IAM

Question

我能够与serverless.yml一起使用：

  iamRoleStatements:
    - Effect: "Allow"
      Action:
        - "sqs:SendMessage"
        - "sqs:ListQueues"
      Resource: "arn:aws:sqs:us-east-1:*:*"

，但我只想将其应用于某个功能。我该怎么做？

从文档中，您需要在resources下创建功能角色，并在您的功能中引用此新角色。

示例：

service: my-test
provider:
  name: aws
  runtime: nodejs6.10
functions:
  hello:
    role: mySQSRole
    handler: handler.hello
resources:
  Resources:
    mySQSRole:
      Type: AWS::IAM::Role
      Properties:
        RoleName: mySQSRole
        AssumeRolePolicyDocument:
          Version: '2012-10-17'
          Statement:
            - Effect: Allow
              Principal:
                Service:
                  - lambda.amazonaws.com
              Action: sts:AssumeRole
        Policies:
          - PolicyName: myPolicyName
            PolicyDocument:
              Version: '2012-10-17'
              Statement:
                - Effect: Allow
                  Action:
                    - sqs:SendMessage
                    - sqs:ListQueues
                  Resource: "arn:aws:sqs:us-east-1:*:*"
