Kibana can't connect to ES having (openstack) LoadBalancer setting

Interesting. According to your experience it looks like Openstack internal LoadBalancer prevents the internal service DNS from resolving. Which would make sense, I guess, if you want another "internal" endpoint.

If that helps, you should be able to keep the existing Elasticsearch service with default options, so Kibana can reach it normally. Then create your own additional Service to target Elasticsearch Pods the way you want:

apiVersion: v1
kind: Service
metadata:
  name: your-service-name-here
  annotations:
    service.beta.kubernetes.io/openstack-internal-load-balancer: "true"
spec:
  externalTrafficPolicy: Local
  type: LoadBalancer
  ports:
  - name: https
    port: 9200
    protocol: TCP
    targetPort: 9200
  selector:
    common.k8s.elastic.co/type: elasticsearch
    elasticsearch.k8s.elastic.co/cluster-name: elasticsearch-sample
