title: Ansible: in case of identical variables
body: <p>I have a file with identical variables, each belong to different service:</p>
  
  <pre><code>#integration/integration.yml
  
  WEB:
  aws_id: &lt;some var&gt;
  aws_outh: &lt;some var&gt;
  
  BACKEND:
  aws_id: &lt;some var&gt;
  aws_outh: &lt;some var&gt;
  </code></pre>
  
  <p>Each service has its own role/task:</p>
  
  <pre><code>roles/web
  roles/backend
  </code></pre>
  
  <p>How to make ansible tasks for each service, to point to the variable that it belongs to?</p>
