title: Firestore authorization for Google Compute engine for app on a docker container
body: <p>I have deployed a Node.js app on a Google compute instance via a Docker container. Is there a recommended way to pass the GOOGLE_APPLICATION_CREDENTIALS to the docker container?</p>
  
  <p>I see the documentation states that GCE has Application Default Credentials (ADC), but these are not available in the docker container. (<a href="https://cloud.google.com/docs/authentication/production" rel="nofollow noreferrer">https://cloud.google.com/docs/authentication/production</a>) </p>
  
  <p>I am a bit new to docker &amp; GCP, so any help would be appreciated.</p>
  
  <p>Thank you! </p>
