I started implementing the Kuberenetes for my simple app. I am facing issue when i use NodePort. IF I use LoadBalancer I can open my url. If I use NodePort it will take long time for trying to load and getting error connection refused. Below is my simple yaml file.

> POD yaml
apiVersion: v1
kind: Pod
metadata:
  name: pod-webapp
  labels:
    app: webapp
spec:
  containers:
  - name:  app
    image: mydockerimage_xxx

> service.yaml

kind: Service
apiVersion: v1
metadata:
  # Unique key of the Service instance
  name: service-webapp
spec:
  ports:
    # Accept traffic sent to port 80
    - name: http
      port: 80
      nodePort: 30080
  selector:
    app: webapp
  type: NodePort
