Question

I want to write my cloud formation yml file in a different file and load them separately. It is easy to do it in the serverless framework but I couldn\'t figure it out how t

Answer 1

you can use the Location property ( https://docs.aws.amazon.com/de_de/serverless-application-model/latest/developerguide/serverless-sam-template-nested-applications.html)

In your case should be something like

template.yml

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
  Sample SAM Template

# Create our resources with separate CloudFormation templates resources:
Resources:
  yourApplicationAliasName:
    Type: AWS::Serverless::Application
    Properties:
      # Lambda function
      Location: ./resources/lambda-functions.yml

and the lambda-functions.yml file

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: AWS Lambda function.
Resources:
  HelloWorldFunction:
    Type: AWS::Serverless::Function 
    Properties:
      CodeUri: hello-world/
      Handler: app.lambdaHandler
      Runtime: nodejs12.x
      Events:
        HelloWorld:
          Type: Api 
          Properties:
            Path: /helloworld
            Method: get

try to use be sam command for packaging as below:

sam package --template template.yml --output-template-file outputtemplate.yml --s3-bucket your-bucket-name

then you need to deploy it:

sam deploy --template-file outputtemplate.yml --stack-name your-bucket-name --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND

** do not forget to remove your previous stack if there is any.
