title: How to work with codepipeline in SAM project?
body: <p>I have a SAM project to deploy my app, I deploy this stack using <code>sam build</code> and <code>sam deploy</code></p>
  <p>I recently added a codepipeline (with all its resources) to the template. The problem is that when I deployed the app, code pipeline created another stack.</p>
  <p>Is there a way to mantain only 1 stack?</p>
  <p>If not I must separate them as nested stack o different stacks?</p>
