fairchild / heroku-dyno-scaler Goto Github PK

Simple AWS lambda function to help scale heroku dynos. The function receives SNS published events that contain a json message specifying the dyno type and desired quantity.

{type: 'worker', quantity: 1}

This can be published from the rails app, or anywhere else that knows a worker will be needed.

To develop:

npm install
node-lamba run

node-lambda run will use the event.json as sample input to the lambda function and run it locally.

To deploy, copy the deploy.env.example file to deploy.env and update its contents to match your needs and then

`node-lambda deploy`

This will zip up the directory, including node_modules, upload the zip to AWS and make the deploy.env variables available on process.env
