Go Lambda

WIP - much of the functionality is not there yet.*

$ go get github.com/guardian/go-lambda

(Though see 'Installing Go' below if you haven't already done so before running this command.)

Handles Guardian-related scaffolding for AWS lambda functions written in Go.

• generate a lambda skeleton project
• generate a RiffRaff artifact, including code and relevant cloudformation

A lambda.json file is used for configuration.

Main commands:

$ go-lambda new
$ go-lambda build
$ go-lambda help

new builds the skeleton project. It will optionally create a Teamcity project for you.

build will generate the RiffRaff artifact including cloudformation. This is useful for local testing, but typically will be run on your build server.

Installing Go

To install Go on Mac, run:

$ brew install golang
$ echo 'GOPATH=~/gocode' >> ~/.bashrc
$ echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.bashrc

$GOPATH is used to store and locate dependencies.

You should locate all projects under this path for now.

Typically, under $GOPATH/src/github.com/guardian.

Go Modules solve this and are much better. However, they are very new and VS Code doesn't support them yet unfortunately, though this is expected imminently (in the next month).
