Hello everyone, I have been trying to deploy elasticsearch helm chart in my k8s cluster consisting of 4 nodes (1 k8s master, 1 controller and 2 computes) after deploying fluentbit and fluentd helm charts which are deployed with success. I have plan to make the EFK (Elasticsearch-Fluentd-Kibana) stack running in my k8s cluster setup for logs management. However I face issues while deploying elasticsearch helm chart using the below command : $ helm install elasticsearch local/elasticsearch --values values_overrides/local-storage.yaml -n openstack Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(StatefulSet.spec): unknown field "strategy" in io.k8s.api.apps.v1.StatefulSetSpec Can anyone point me if I missing anything? What are the prerequisites before deploying elasticsearch chart which intended to use local storage/pv in my case avoiding the default S3 storage as per the chart? Thanks for your pointers and suggestions. ' best regards, SanjayK
