Upgrade Ruby on Elastic Beanstalk
<p>How does ruby version get set and updated on ELB?</p>

<p>I've been using <code>ruby 2.2.2</code> on our qa and staging env's for about 8 months now. I just setup our production env Monday and it wouldn't deploy as it said ruby was set to 2.2.3 and my gemfile said 2.2.2. I updated and redeployed and everything seemed to be fine.</p>

<p>I came back to the qa/staging env's and can't get it to update to ruby 2.2.3. Kept saying ruby version is 2.2.2 and Gemfile is 2.2.3</p>

<p>I upgraded (through elb ui):</p>

<p><code>64bit Amazon Linux 2015.03 v1.3.1 running Ruby 2.2 (Passenger Standalone)</code> to</p>

<p><code>64bit Amazon Linux 2015.09 v2.0.6 running Ruby 2.2 (Passenger Standalone)</code></p>

<p>Now it says <code>Your Ruby version is 2.2.3, but your Gemfile specified 2.2.2</code>. There has to be an easier way to do this.</p>
