Reference Serverless Core Variables

Serverless initializes core variables which are used internally by the Framework itself. Those values are exposed via the Serverless Variables system and can be re-used with the {sls:} variable prefix.

The following variables are available:

instanceId

A random id which will be generated whenever the Serverless CLI is run. This value can be used when predictable random variables are required.

service: new-service
provider: aws

functions:
  func1:
    name: function-1
    handler: handler.func1
    environment:
      APIG_DEPLOYMENT_ID: ApiGatewayDeployment${sls:instanceId}

stage

The stage used by the Serverless CLI. The ${sls:stage} variable is a shortcut for ${opt:stage, self:provider.stage, "dev"}.
