AWS SNS - Lambda Slack integration written in Go

Using (just recently) released official support for Go in lambda. Inspired by terranova's article.

Install

start with dep ensure

Follow steps in aws manual:

GOOS=linux go build -o main
zip deployment.zip main

upload this file in lambda function setup
make sure you specify ENV variable WEBHOOK_URL with appropriate slack webhook URL
configure lambda trigger as SNS

My usecase

AWS Healhcheck integration with slack, where Healthcheck sends notifications to the SNS which triggers the lambda.
