title: Setup Continuous deployment with Cloud build through build pack
body: <p>I am trying to set up a node js app on Cloud run which should contain only production-level build code in our container registry image. I want to achieve this through build pack on Cloud run.</p>
  <p>I have a few doubts on the same as below:</p>
  <ul>
  <li>What is buildpack directory in cloud build configurations?</li>
  <li>Is this should be build directory? If yes then how can we build our code through CI-CD?</li>
  </ul>
  <p>Referring to this guide for setup - <a href="https://cloud.google.com/run/docs/continuous-deployment-with-cloud-build#setup-cd" rel="nofollow noreferrer">https://cloud.google.com/run/docs/continuous-deployment-with-cloud-build#setup-cd</a></p>
  <p>Thanks</p>
