Generated using TypeDoc
Abstract AWS Lambda function, that acts as a container to instantiate and run components and expose them via external entry point. All actions are automatically generated for commands defined in ICommandable components. Each command is exposed as an action defined by "cmd" parameter.
Container configuration for this Lambda function is stored in
"./config/config.yml"file. But this path can be overriden byCONFIG_PATHenvironment variable.Configuration parameters
