Elasticsearch cluster deletes itself


we have a strange problem with our elasticsearch cluster in kubernetes.

sometimes it happens that the entire cluster is simply deleted. suddenly all pvc's, configmaps, secrets and statefulsets are gone. only the elasticsearch resource is still available.

at first glance I couldn't find anything in the logs.


  • gcloud kubernetes (1.16.15-gke.6000)
  • eck operator (1.1.1)

if further information is required, please contact me

You likely hit this K8S issue.
See the ECK documentation here.
We are trying to avoid that situation since 1.3.1.
