title: How can I list and delete GCP AppEngine images from the command line?
body: <p>I'd like to delete my old unused AppEngine images from Google Cloud Platform, so that I'm not charged for storing them.</p>
  
  <p>I can manually list and delete the images created for my GCP AppEngine project from this URL:
  <a href="https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID" rel="nofollow noreferrer">https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID</a></p>
  
  <p>(Obviously, replace GOOGLE_CLOUD_PROJECT_ID with an appropriate GCP project id.)</p>
  
  <p>Is there a way to list them from the command line?  e.g. via <code>gcloud</code>?</p>
  
  <p>This doesn't work as I would expect:</p>
  
  <pre><code>$ gcloud compute images list --no-standard-images
  Listed 0 items.
  </code></pre>
  
  <p>Neither does this:</p>
  
  <pre><code>$ gcloud container images list 
  Listed 0 items.
  Only listing images in gcr.io/GOOGLE_CLOUD_PROJECT_ID. Use --repository to list images in other repositories.
  </code></pre>
  
  <p>It's a little painful to go in and delete lots of these manually since each image under <a href="https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID/US/appengine" rel="nofollow noreferrer">https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID/US/appengine</a> is in a separate directory that I have to first click into to select the image and then click the delete button, and then go back out to  the appengine directory and start the process again for any other images.</p>
