Shoryuken Serverless

This is a PoC for making existing Shoryuken (Active Job or Standard workers) to work with Lambda Ruby using SQS as an event source.

Shoryuken Lambda

Check this sample Lambda for an example of Shoryuken compatible Lambda

It is important to load Rails outside the method handler so that it gets “cached” while your Lambda (container) is still hot.

Lambdas vs Queues

The number of Lambdas or queues is entirely up to you. You can use multiple queues and Lambdas - it is all up-to-you.

Deploy your Lambdas

For deploying your Ruby Lambdas, you need to vendorize your gems with the same container Ruby Lambdas run.

docker run -v `pwd`:`pwd` -w `pwd` -i -t lambci/lambda:build-ruby2.5 bundle install --deployment --without development test
docker run -v `pwd`:`pwd` -w `pwd` -i -t lambci/lambda:build-ruby2.5 gem pristine --all

Deploy with aws-cdk

This sample app uses aws-cdk for making it easy to create stacks and deploy Lambda.

For deploying your stack using this sample project, you can run the commands below (or ./deploy.sh).

(
  cd rails_sample_app
  docker run -v `pwd`:`pwd` -w `pwd` -i -t lambci/lambda:build-ruby2.5 bundle install --deployment --without development test
  docker run -v `pwd`:`pwd` -w `pwd` -i -t lambci/lambda:build-ruby2.5 gem pristine --all
)
npm run build
cdk deploy
