Access Minikube Loadbalancer Service From Host Machine

I am trying to learn how to use Kubernetes with Minikube and have the following deployment and service:

---
kind: Service
apiVersion: v1
metadata:
  name: exampleservice
spec:
  selector:
    app: myapp
  ports:
  - protocol: "TCP"
    # Port accessible inside cluster
    port: 8081
    # Port to forward to inside the pod
    targetPort: 8080
    # Port accessible outside cluster
    nodePort: 30002
  type: LoadBalancer
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: myappdeployment
spec:
  replicas: 5
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp
        image: tutum/hello-world
        ports:
        - containerPort: 8080

I expect to be able to hit this service from my local machine at

http://192.168.64.2:30002

As per the command: minikube service exampleservice --url but when I try to access this from the browser I get a site cannot be reached error.

Some information that may help debugging:

kubectl get services --all-namespaces:

NAMESPACE     NAME                   TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                  AGE

I am running minikube on OSX.

You can use External IPs, as described in k8s docs. Update the service as shown below (where I assume 192.168.64.2 is your minikube IP):

kind: Service
apiVersion: v1
metadata:
  name: exampleservice
spec:
  selector:
    app: myapp
  ports:
  - protocol: "TCP"
    # Port accessible inside cluster
    port: 8081
    # Port to forward to inside the pod
    targetPort: 80
    # Port accessible outside cluster
    nodePort: 30002
  type: LoadBalancer
  externalIPs:
  - 192.168.64.2

Now you can access your application at http://192.168.64.2:8081/

If you need to access the application at 30002, you can use it like this

    kind: Service
    apiVersion: v1
    metadata:
      name: exampleservice
    spec:
      selector:
        app: myapp
      ports:
      - protocol: "TCP"
        # Port accessible inside cluster
        port: 8081
        # Port to forward to inside the pod
        targetPort: 80
        # Port accessible outside cluster
        nodePort: 30002
      type: NodePort

Your deployment file does not look correct to me.

delete it kubectl delete deploy/myappdeployment

use this to create again.

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  labels:
    app: myapp
  name: myappdeployment
spec:
  replicas: 5
  selector:
    matchLabels:
      app: myapp
  strategy: {}
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - image: tutum/hello-world
        name: myapp
        ports:
        - containerPort: 80
