notifyhub

A multi-slack serverless approach to AWS Outage Notifications. Inspired by aws-status-in-slack, but serverless.

How does it work?

There are two lambdas using serverless. One polls AWS and keeps an history on DynamoDB (nh-poll), forwarding to SNS.

The other (nh-slack) is a SNS Handler via HTTPS which pushes to the right place.

npm install -g serverless
npm install

go get github.com/constabulary/gb/...
gb vendor restore
bash ./build.sh

serverless deploy

Create the SNS Topic nh-dev
Create an Incoming Webhook on Slack, and take note of the three last parameters on its URL (we'll call it TOKENA TOKENB and TOKENC)
Create subscriptions to your lambda by means of HTTP, in the format:
