I am trying to connect my elastic search pod, to ports 9200 and 9300. When I go to:

http://localhost:$IP_FROM_KUBECTL_PROXY(usually 8001)/api/v1/namespaces/default/pods/$POD_NAME/proxy/

I see the following error:

Error: 'net/http: HTTP/1.x transport connection broken: malformed HTTP status code "is"'
Trying to reach: 'http://172.17.0.5:9300/'

What I did is, running :

kubectl run elasticsearch --image=elasticsearch:6.6.1 -labels="elasticsearch" --env="discovery.type=single-node" --port=9200 --port=9300

and running the following service:

kind: Service
apiVersion: v1
metadata:
  name: elasticsearch
spec:
  selector:
    host: elasticsearch
    subdomain: for-kibana
    app: elasticsearch
  ports:
  - protocol: TCP
    name: serving
    port: 9200
    targetPort: 9200
  - protocol: TCP
    name: node2node
    port: 9300
    targetPort: 9300

It's weird, because when I just use port 9200, all works, but when I run with 9300, its fail.
