Serverless Cloudformation Parameters

Generates Cloudformation parameters for Serverless framework.

Use Case

Serverless does not create parameters when it compiles Cloudformation templates. This allows for developers to create parameters that can be used for deployment.

Installation

npm install serverless-cloudformation-parameters --save
sls plugin install -n serverless-cloudformation-parameters 

Usage

serverless.yml

  service: example
  plugins:
    - serverless-cloudformation-parameters

    parameters:
      SomeEnvVarPrefilled:
          Type: String
          Default: foo
          Description: A default parameter, filled with a value from your env when deployed with `sls deploy`
  
  provider:
    name: aws
    runtime: python2.7
    environment:
      # Use Ref to refer to parameter.
