CommandableLambdaFunction

Extends: LambdaFunction

Description

The CommandableLambdaFunction class allows you to create AWS Lambda function that acts as a container to instantiate and run components and expose them via an external entry point.

Important points

• All actions are automatically generated for commands defined in ICommandable components. Each command is exposed as an action defined by the “cmd” parameter.

• Container configuration for this Lambda function is stored in "./config/config.yml" file. But this path can be overriden by CONFIG_PATH environment variable.

• Note: This component has been deprecated. Use LambdaController instead.
