I'm trying to run Elasticsearch and Kibana on Kubernetes cluster (same namepace). I created Pod and a Service for Elasticsearch and for Kibana. When I enter to the elasticsearch website (http://localhost:8001/api/v1/namespaces/default/pods/elasticsearch/proxy/), everything seems fine, but when I enter to Kibana's website, I see "Kibana did not load properly. Check the server output for more information.".

The Kibana pod's logs, are the following:

{"type":"error","@timestamp":"2019-03-04T19:27:21Z","tags":["warning","stats-collection"],"pid":1,"level":"error","error":{"message":"Request Timeout after 30000ms","name":"Error","stack":"Error: Request Timeout after 30000ms\n    at /usr/share/kibana/node_modules/elasticsearch/src/lib/transport.js:355:15\n    at Timeout.<anonymous> (/usr/share/kibana/node_modules/elasticsearch/src/lib/transport.js:384:7)\n    at ontimeout (timers.js:436:11)\n    at tryOnTimeout (timers.js:300:5)\n    at listOnTimeout (timers.js:263:5)\n    at Timer.processTimers (timers.js:223:10)"},"message":"Request Timeout after 30000ms"}

Those are the yaml files:

deployment_elasticsearch.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: elasticsearch
  labels:
    service: elasticsearch
spec:
  ports:
  containers:
  - name: elasticsearch
    image: elasticsearch:6.6.1
    ports:
    - containerPort: 9200
    - containerPort: 9300
    env:
    - name: discovery.type
      value: "single-node"

deployment_elasticsearch_service.yaml:

apiVersion: v1
kind: Service
metadata:
  name: elasticsearch
  labels:
    service: elasticsearch
spec:
  ports:
  - port: 9200
    name: serving
  - port: 9300
    name: node-to-node
  selector:
    service: elasticsearch

deployment_kibana.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: kibana
  labels:
    service: kibana
spec:
  ports:
  containers:
  - name: kibana
    image: kibana:6.6.1
    ports:
    - containerPort: 5601

deployment_kibana_service.yaml:

apiVersion: v1
kind: Service
metadata:
  name: kibana
  labels:
    service: kibana
spec:
  ports:
  - port: 5601
    name: serving
  selector:
    service: kibana

Also, when I enter to kibana pod, and run "$curl http://elasticsearch:9200", I get the elasticsearch home page (so I think that kibana can reach elasticsearch).

EDIT This is the grep error logs for kibana:

From online research, I think that the problem is that els and kibana can't talk to one another. Can you know why?

Edit 2, describe logs:
