+{% capture overview %}
+
+This page shows how to create a Kubernetes Service object that external
+clients can use to access an application running in a cluster. The
+Service exposes a stable IP address and provides load balancing for
+an application that has two running instances.
+
+{% endcapture %}
+
+
+{% capture prerequisites %}
+
+* Install [kubectl](http://kubernetes.io/docs/user-guide/prereqs).
+
+* Create a Kubernetes cluster, including a running Kubernetes
+  API server. One way to create a new cluster is to use
+  [Minikube](/docs/getting-started-guides/minikube).
+
+* Configure `kubectl` to communicate with your Kubernetes API server. This
+  configuration is done automatically if you use Minikube.
+
+{% endcapture %}
+
+
+{% capture objectives %}
+
+* Run two instances of a Hello World application.
+* Create a Service object that exposes an external IP address.
+* Use the Service object to access the running application.

+
+### Creating a service for an application running in two pods
+
+1. Run a Hello World application in your cluster:
+
+        kubectl run hello-world --replicas=2 --labels="run=load-balancer-example" --image=gcr.io/google-samples/node-hello:1.0  --port=8080
+
+    The preceding command creates a
+    [Deployment](/docs/user-guide/deployments/)
+    object and an associated
+    [ReplicaSet](/docs/user-guide/replicasets/)
+    object. The ReplicaSet has two
+    [Pods](/docs/user-guide/pods/),
+    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 the ReplicaSet:
+
+        kubectl get replicasets hello-world
+        kubectl describe replicasets hello-world
+
+1. List the pods that are running the Hello World application:
+
+        kubectl get pods --selector="run=load-balancer-example"
+
+    The output is similar to this:
+
+        NAME                           READY     STATUS    RESTARTS   AGE
+        hello-world-2189936611-8fyp0   1/1       Running   0          6m
+        hello-world-2189936611-9isq8   1/1       Running   0          6m
+
+1. Create a Service object that exposes the deployment:
+
+        kubectl expose deployment hello-world --type="LoadBalancer" --name="example-service"
+
+1. Display the IP addresses for your service:
+
+        kubectl get services example-service
+
+   The output shows the internal IP address and the external IP address of
+   your service. If the external IP address shows as `<pending>`, repeat the
+   command.
+
+   Note: If you are using Minikube, you don't get an external IP address. The
+   external IP address remains in the pending state.
+
+       NAME              CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
+       example-service   10.0.0.160   <pending>     8080/TCP   40s
+
+1. Use your service to access the Hello World application:
+
+        curl <your-external-ip-address>:8080
+
+    where `<your-external-ip-address>` is the external IP address of your
+    service.
+
+    The output is a hello message from the application:
+
+        Hello Kubernetes!
+
+    Note: If you are using Minikube, enter these commands:
+
+        kubectl cluster-info
+        kubectl describe services example-service
+
+    The output displays the IP address of your Minikube node and the NodePort
+    value for your service. Enter this command to access the Hello World
+    application:
+
+        curl <minikube-node-ip-address>:<service-node-port>
+
+    where `<minikube-node-ip-address>` us the IP address of your Minikube node,
+    and `<service-node-port>` is the NodePort value for your service.
+
+### Using a service configuration file
+
+As an alternative to using `kubectl expose`, you can use a
+[service configuration file](/docs/user-guide/services/operations)
+to create a Service.
+
+{% endcapture %}
+
+
+{% capture cleanup %}
+
+To delete the Service, enter this command:
+
+    kubectl delete services example-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
