I am trying to run elasticsearch on kubernetes following https://github.com/pires/kubernetes-elasticsearch-cluster

The yaml file that I am using to deploy on the cluster looks like this:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: es5-master
  ...
spec:
  ...
    spec:
      initContainers:
      - name: init-sysctl
        image: busybox
        imagePullPolicy: IfNotPresent
        command: ["sysctl", "-w", "vm.max_map_count=262144"]
        securityContext:
          privileged: true
      containers:
      - name: es5-master
        securityContext:
          privileged: false
          capabilities:
            add:
              - IPC_LOCK
              - SYS_RESOURCE
        image: quay.io/pires/docker-elasticsearch-kubernetes:5.6.0
        imagePullPolicy: Always
        env:
        - name: NAMESPACE
          valueFrom:
            fieldRef:
              fieldPath: metadata.namespace
        - name: NODE_NAME
          valueFrom:
            fieldRef:
              fieldPath: metadata.name
        - name: "CLUSTER_NAME"
          value: "myes5db"
        - name: "NUMBER_OF_MASTERS"
          value: "2"
        - name: NODE_MASTER
          value: "true"
        - name: NODE_INGEST
          value: "false"
        - name: NODE_DATA
          value: "false"
        - name: HTTP_ENABLE
          value: "false"
        - name: "ES_JAVA_OPTS"
          value: "-Xms256m -Xmx256m"
        - name: "NETWORK_HOST"
          value: "_eth0_"
        ports:
        - containerPort: 9300
          name: transport
          protocol: TCP
        livenessProbe:
          tcpSocket:
            port: 9300
        volumeMounts:
        - name: storage
          mountPath: /data
      volumes:
          - emptyDir:
              medium: ""
            name: "storage"

The error that I am getting is:

I am running Es version 1.7 and that's why I renamed this new one to elasticsearch5. I hope this naming is not the cause of the problem. I initially didn't have eth0 for NETWORK_HOST , reviewing Troubleshooting par from the readme doc, I added in but now getting 253 hex: fd error. Other network host values didnt work.

I really appreciate any ideas regarding that.
