<p>We'd like to have a separate test and prod project on the Google Cloud Platform but we want to reuse the same docker images in both environments. Is it possible for the Kubernetes cluster running on the test project to use images pushed to the prod project? If so, how?</p>

<p>Looking at your question, I believe by account you mean project.</p>

<p>The <a href="https://cloud.google.com/container-registry/docs/#pulling_from_the_registry" rel="nofollow">command</a> for pulling an image from the registry  is:</p>

<pre><code>$ gcloud docker pull gcr.io/your-project-id/example-image
</code></pre>

<p>This means as long as your account is a member of the project which the image belongs to, you can pull the image from that project to any other projects that your account is a member of.</p>
