title: odoo deployment in auto-scaling scenario
body: <p>I am trying to understand how to prepare a fresh server to deploy into a currently running cluster. Or as a replacement for a failed instance.</p>
  <p>Other than the content of the source distribution (plus any added custom resources), what else needs to be deployed?</p>
  <p>I have discovered images being served from the 'data_dir' filestore. Some resources like fontawesome files and certain icons are not being served.</p>
  <p>Should the 'data_dir' location be shared between multiple instances in a cluster? And should it survive server failures?</p>
  <p>Any other tips also appreciated?</p>
