I have written about this or similar topics before in both Post-Deployment script on Elastic Beanstalk: Restart Delayed Job as well as Convenient way to run app commands in Elastic Beanstalk.

Elastic Beanstalk is great! It is very easy to get a Rails app up and running on AWS quickly. Perfect for an app developer that prefers not to deal directly with sysops but still wants to deploy to and leverage the services on AWS.

UPDATE 2021!

When the need arise to SSH into your EB instance and execute a command in your app, you might run into issues. I describe in an earlier post how to trigger a restart of DelayedJob after each deployment. In that particular case, one issue was that the command was not running under the correct ruby installation. Turns out that we can make use of EB’s own support scripts to help us out.
