I have a 3 node cluster created on kubernetes playground

The 3 nodes as seen on the UI are :

192.168.0.13 : Master
192.168.0.12 : worker
192.168.0.11 : worker

I have a front end app connected to backend mysql.

The deployment and service definition for front end is as below.

apiVersion: v1
kind: Service
metadata:
  name: springboot-app
spec:
  type: NodePort
  ports:
  - port: 8080
  selector:
    app: springboot-app
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: springboot-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: springboot-app
  template:
    metadata:
      labels:
        app: springboot-app
    spec:
      containers:
      - image: chinmayeepdas/springbootapp:1.0
        name: springboot-app
        env:
        - name: DATABASE_HOST
          value: demo-mysql
        - name: DATABASE_NAME
          value: chinmayee
        - name: DATABASE_USER
          value: root
        - name: DATABASE_PASSWORD
          value: root
        - name: DATABASE_PORT
          value: "3306"
        ports:
        - containerPort: 8080
          name: app-port

My PODs for UI and backend are up and running.
