AWS Flow Framework for Ruby: Booking Sample Application

The Booking sample demonstrates a synchronization workflow pattern. It waits for two activities to complete: a car reservation and airline reservation. When both activities complete, it sends a confirmation. All activities are performed asynchronously.

Prerequisites

The AWS Flow Framework for Ruby is required, which can be obtained and installed using the information here:

• https://aws.amazon.com/swf/flow/

If you already have Ruby and RubyGems installed, you can install the framework by opening a terminal window and typing:

gem install aws-flow

For more information about setting up the AWS Flow Framework for Ruby, see Installing the AWS Flow Framework for Ruby in the AWS Flow Framework for Ruby Developer Guide.

Downloading the Sample Code

Run the Sample

To run the Booking sample:

1. Open two separate terminal windows and, in each one, change to the booking directory in the location where you cloned or unarchived the sample code. For example:

   cd ~/Downloads/aws-flow-ruby-samples/samples/booking
   

2. In each command-line (terminal) window, execute the following commands, substituting your AWS Access keys for the example values.

   On Linux, OS X or Unix:

   export AWS_ACCESS_KEY_ID='your-access-key'
   export AWS_SECRET_ACCESS_KEY='your-secret-key'
   export AWS_REGION='your-aws-region'
   

   On Windows:

   set AWS_ACCESS_KEY_ID=your-access-key
   set AWS_SECRET_ACCESS_KEY=your-secret-key
   set AWS_REGION=your-aws-region
   

3. Execute the following commands, one in each of the terminal windows:

   aws-flow-ruby -f worker.json
   
   ruby starter.rb
