Attach a preexisting role in template.yml file while creating sam application through console

Question

I am trying to create a sam application with a pre existing role through sam-cli.By default the sam clil creates new user roles with basic lambda exuection policies ,but as i want to run x-ray on my sam application i would want application to be created with existing user role.

Here is my template.yml

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Resources:
  POCLambdaExecutionRole:
  Type: 'AWS::IAM::Role'
  SAMLocal:
    Type: AWS::Serverless::Function
    Properties:
      Handler: SAMLocal.lambda_handler
      Runtime: python2.7
    TracingConfig:
      Mode: Active
      Environment:
        Variables:
          dev_table: "MessageQueue"
      Events:
        SAMLocal:
          Type: Api
          Properties:
            Path: /
            Method: GET
  SAMLocal1:
    Type: AWS::Serverless::Function
    Properties:
      Handler: SAMLocal.lambda_handler
      Runtime: python2.7

How can i achieve the same .

Answer 1

you need to put existing role in your yaml file in ARN format

role: arn:aws:iam::XXXXXX:role/role
