I create two containers in two pods in k8s, elasticsearch and kibana.
kibana container needs to access elasticsearch endpoint on the port 9200. So I set the env to be http://es-cluster-1.elasticsearch.default.svc.local:9200 based on this doc: https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/.
But in kibana logs I can see it can't reach to this endpoint. What did I do wrong?
