title: What's the equivalent to shared Docker volumes in GCE?
body: <p>When developing with containers locally, <code>docker-compose</code> lets you create shared volumes that all of your containers can access. You can easily drop small credential files onto these volumes from one container, and have another container use them.</p>
  <p>I'm trying to find something similar in Google Compute Engine but I haven't been able to find anything analagous.</p>
  <ul>
  <li>Compute Engine disks cannot be shared between instances</li>
  <li>Filestore instances start at a minimum of 1 Tb and are expensive overkill</li>
  </ul>
  <p>Is there anything similar in Google Compute Engine to the concept of shared volumes in Docker, in terms of how it can be mounted to the instances, shared among instances, and small/cheap?</p>
  <p>Does such a concept not exist in GCE, and is such a feature perhaps available, but only available, in Google Kubernetes Engine (GKE)?</p>
