Example of IronWorker that uses gems

Setup

1. Create a new project on Ironworker, and a new worker within it

• Create a new project/worker for this project
• notice a link on the 'Getting Started' page for your worker's iron.json

2. Create the base for this project

• Git clone this project onto your local machine
• Download your iron.json file from your worker on iron.io to this repo

3. Note that the Gemfile specifies you should use Ruby 2.1.0, so install it

• $ rvm install 2.1.0

Configure and test the worker locally

1. Configure this project

• Create a /config/config.json file
• Copy and modify contents of config/example_config.json to config/config.json

2. Test this worker

• $ bundle install --standalone
  • creates a bundle of all needed gems within your repo
• $ ruby soa_worker.rb
  • expects you to have an 'SOA_queue' on your regional SQS with JSON messages like:
    • { url: 'http://cadetdynamo.herokuapp.com/api/v3/cadet/soumya.ray.json' }
    • { url: 'http://cadetdynamo.herokuapp.com/api/v3/cadet/chenlizhan.json' }

Deploy and run this worker

3. Upload your worker

• $ zip -r soa_worker.zip .
  • creates a zip of all files in this folder
• $ iron worker upload --zip soa_worker.zip --name soa_worker iron/images:ruby-2.1 ruby soa_worker.rb
  • creates a zip of your entire repo

4. Run your worker remotely

• $ iron worker queue --wait soa_worker
  • runs your worker on iron.io
