Go programming on Lambda with Apex

Apex is a tool for building, deploying, and managing AWS Lambda functions. It provides wrappers for Go (using a Node.js shim). Currently, there is not a way to run native Go code on Lambda without such a shim. This recipe will explore creating Go Lambda functions and deploying them with Apex.

Getting ready

Configure your environment according to these steps:

Download and install Go on your operating system (https://golang.org/doc/install) and configure your GOPATH environment variable.
Open a terminal/console application.
Navigate to your GOPATH/src directory and create a project directory, for example, $GOPATH/src/github.com/yourusername/customrepo. All code will be run and modified from this directory.
Optionally, install the latest tested version of the code using thego get github.com/agtorre/go-cookbook/... command.
Install Apex from http://apex.run/.
Run the go get github.com/apex/go-apex command.

How to do it...

These steps cover writing and running your application...
