#Tencent-SCF Variables

Variables allow users to dynamically replace config values in serverless.yml config. They are especially useful when providing secrets for your service to use and when you are working with multiple stages.

The Serverless framework provides a powerful variable system which allows you to add dynamic data into your serverless.yml. With Serverless Variables, you'll be able to do the following:

  • Reference & load variables from environment variables

Note: You can only use variables in serverless.yml property values, not property keys. So you can't use variables to generate dynamic logical IDs in the custom resources section for example.

#Reference variables from environment variables

To reference variables from environment variables, use the ${env:someProperty} syntax in your serverless.yml.

service: new-service

provider:
  name: tencent
  runtime: Nodejs8.9
  credentials: ~/.tencent/credentials
  environment:
    variables:
      ENV_FIRST: ${env:TENCENTCLOUD_APPID}
