+
+This page shows how to create a Kubernetes Service object that exposes an
+external IP address.
+
+{{% /capture %}}
+
+
+{{% capture prerequisites %}}
+
+ * Install [kubectl](/docs/tasks/tools/install-kubectl/).
+
+ * Use a cloud provider like Google Kubernetes Engine or Amazon Web Services to
+ create a Kubernetes cluster. This tutorial creates an
+ [external load balancer](/docs/tasks/access-application-cluster/create-external-load-balancer/),
+ which requires a cloud provider.
+
+ * Configure `kubectl` to communicate with your Kubernetes API server. For
+ instructions, see the documentation for your cloud provider.

+
+## Creating a service for an application running in five pods
+
+1. Run a Hello World application in your cluster:
+
+{{< codenew file="service/load-balancer-example.yaml" >}}
+
+```shell
+kubectl apply -f https://k8s.io/examples/service/load-balancer-example.yaml
+```
+
+
+The preceding command creates a
+    [Deployment](/docs/concepts/workloads/controllers/deployment/)
+    object and an associated
+    [ReplicaSet](/docs/concepts/workloads/controllers/replicaset/)
+    object. The ReplicaSet has five
+    [Pods](/docs/concepts/workloads/pods/pod/),
+    each of which runs the Hello World application.
+
+1. Display information about the Deployment:
+
+        kubectl get deployments hello-world
+        kubectl describe deployments hello-world
+
+1. Display information about your ReplicaSet objects:
+
+        kubectl get replicasets
+        kubectl describe replicasets
+
+1. Create a Service object that exposes the deployment:
+
+        kubectl expose deployment hello-world --type=LoadBalancer --name=my-service
+
+1. Display information about the Service:
+
+        kubectl get services my-service
+
+    The output is similar to this:
+
+        NAME         TYPE           CLUSTER-IP     EXTERNAL-IP      PORT(S)    AGE
+        my-service   LoadBalancer   10.3.245.137   104.198.205.71   8080/TCP   54s
+
+    Note: If the external IP address is shown as \<pending\>, wait for a minute
+    and enter the same command again.
+
+1. Display detailed information about the Service:
+
+        kubectl describe services my-service
+
+    The output is similar to this:
+
+        Name:           my-service
+        Namespace:      default
+        Labels:         app.kubernetes.io/name=load-balancer-example
+        Annotations:    <none>
+        Selector:       app.kubernetes.io/name=load-balancer-example
+        Type:           LoadBalancer
+        IP:             10.3.245.137
+        LoadBalancer Ingress:   104.198.205.71
+        Port:           <unset> 8080/TCP
+        NodePort:       <unset> 32377/TCP
+        Endpoints:      10.0.0.6:8080,10.0.1.6:8080,10.0.1.7:8080 + 2 more...
+        Session Affinity:   None
+        Events:         <none>
+
+    Make a note of the external IP address (`LoadBalancer Ingress`) exposed by
+    your service. In this example, the external IP address is 104.198.205.71.
+    Also note the value of `Port` and `NodePort`. In this example, the `Port`
+    is 8080 and the `NodePort` is 32377.
+
+1. In the preceding output, you can see that the service has several endpoints:
+   10.0.0.6:8080,10.0.1.6:8080,10.0.1.7:8080 + 2 more. These are internal
+   addresses of the pods that are running the Hello World application. To
+   verify these are pod addresses, enter this command:
+
+        kubectl get pods --output=wide
+
+    The output is similar to this:
+
+        NAME                         ...  IP         NODE
+        hello-world-2895499144-1jaz9 ...  10.0.1.6   gke-cluster-1-default-pool-e0b8d269-1afc
+        hello-world-2895499144-2e5uh ...  10.0.1.8   gke-cluster-1-default-pool-e0b8d269-1afc
+        hello-world-2895499144-9m4h1 ...  10.0.0.6   gke-cluster-1-default-pool-e0b8d269-5v7a
+        hello-world-2895499144-o4z13 ...  10.0.1.7   gke-cluster-1-default-pool-e0b8d269-1afc
+        hello-world-2895499144-segjf ...  10.0.2.5   gke-cluster-1-default-pool-e0b8d269-cpuc
+
+1. Use the external IP address (`LoadBalancer Ingress`) to access the Hello
+   World application:
+
+        curl http://<external-ip>:<port>
+
+    where `<external-ip>` is the external IP address (`LoadBalancer Ingress`)
+    of your Service, and `<port>` is the value of `Port` in your Service
+    description.
+    If you are using minikube, typing `minikube service my-service` will
+    automatically open the Hello World application in a browser.
+
+    The response to a successful request is a hello message:
+
+        Hello Kubernetes!
+
+{{% /capture %}}
+
+
+{{% capture cleanup %}}
+
+To delete the Service, enter this command:
+
+        kubectl delete services my-service
+
+To delete the Deployment, the ReplicaSet, and the Pods that are running
+the Hello World application, enter this command:
+
+        kubectl delete deployment hello-world
