<p>Trying to get <a href="https://github.com/thingsboard/thingsboard/blob/release-2.3/k8s/thingsboard.yml" rel="noreferrer">ThingsBoard</a> running on google cloud. </p>

<p>I am now seeing the following error:</p>

<blockquote>
  <p>Error during sync: error running load balancer syncing routine:
  loadbalancer thingsboard-tb-ingress--013d7ab9087175d7 does not exist:
  CreateUrlMap: googleapi: Error 400: Invalid value for field
  'resource': '{ "name":
  "k8s-um-thingsboard-tb-ingress--013d7ab9087175d7", "hostRule": [{
  "host": ["*"], "...'. Invalid path pattern, invalid</p>

<p>kubectl describe ingress gives me the following:</p>

<p>What am I missing here?</p>

<p>I forgot to specify kubernetes.io/ingress.class: "nginx" annotation. If you don't specify any kubernetes.io/ingress.class - GKE will consider using its own ingress which does not support regexps and gives the error mentioned.</p>
