title: Docker: "Unable to pull 'tomcat:8.5' : no matching manifest for linux/arm/v7 in the manifest list entries"
body: <p>On Raspberry Pi, I got an error when I tried to set up ODK-X Sync Endpoint.</p>
  <p>I referred to the instruction from <a href="https://docs.odk-x.org/sync-endpoint-manual-setup/" rel="nofollow noreferrer">https://docs.odk-x.org/sync-endpoint-manual-setup/</a></p>
  <p>This is the command I ran:</p>
  <p><code>$ mvn clean install</code></p>
  <p>The error message is as below:</p>
  <p><code>Failed to execute goal io.fabric8:docker-maven-plugin:0.34.1:build (start) on project sync-endpoint-docker-swarm: Unable to pull 'tomcat:8.5' : no matching manifest for linux/arm/v7 in the manifest list entries</code></p>
  <p>How can I solve this problem?</p>
