Lambda Service

This service is github.com/aws/aws-sdk-go/service/lambda.Lambda proxy

To check all supported method run

    endly -s="aws/lambda"

To check method contract run endly -s="aws/lambda" -a=methodName

    endly -s="aws/lambda" -a=deployFunction

On top of that service implements the following helper methods:

  • deployFunction: creates or modifies function with specified policies
  • recreateFunction: drop if exists and create new function
  • dropFunction: drop function with dependencies
  • setupPermission: add permission if it does not exists

Usage

Prerequisites:

AWS credentials
