Understanding Kubernetes Architecture Cluster

I am trying to deploy nginx on kubernetes, kubernetes version is v1.5.2, I have deployed nginx with 3 replica, YAML file is below,

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: deployment-example
spec:
  replicas: 3
  revisionHistoryLimit: 2
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.10
        ports:
        - containerPort: 80

and now I want to expose its port 80 on port 30062 of node, for that I created a service below,

kind: Service
apiVersion: v1
metadata:
  name: nginx-ils-service
spec:
  ports:
    - name: http
      port: 80
      nodePort: 30062
  selector:
    app: nginx
  type: LoadBalancer

this service is working good as it should be, but it is showing as pending not only on kubernetes dashboard also on terminal.

so please help me to resolve this issue. Thanks ...

It looks like you are using a custom Kubernetes Cluster (using minikube, kubeadm or the like). In this case, there is no LoadBalancer integrated (unlike AWS or Google Cloud). With this default setup, you can only use NodePort (more info here: https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport) or an Ingress Controller. With the Ingress Controller you can setup a domain name which maps to your pod (more information here: https://kubernetes.io/docs/concepts/services-networking/ingress/#ingress-controllers)
