AWS Flow Framework for Ruby: Periodic Sample Application

The Periodic sample periodically executes an activity in a long-running workflow. The ability to continue executions as new executions so that an execution can run for very extended periods of time is demonstrated.

Prerequisites

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

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

To view or download the code for all of the AWS Flow Framework for Ruby recipes and samples, go to:

Run the Sample

To run the Periodic sample:

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

    cd ~/Downloads/aws-flow-ruby-samples/Samples/periodic/lib

  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:

    ruby error_reporting_activity.rb

ruby periodic_activity.rb

ruby periodic_workflow.rb

ruby periodic_workflow_starter.rb
