Kubernetes cluster. To make the `hello-node` Container accessible from outside the
Kubernetes virtual network, you have to expose the Pod as a
Kubernetes [*Service*](/docs/concepts/services-networking/service/).
1. Expose the Pod to the public internet using the `kubectl expose` command:
```shell
kubectl expose deployment hello-node --type=LoadBalancer --port=8080
```
The `--type=LoadBalancer` flag indicates that you want to expose your Service
outside of the cluster.

On cloud providers that support load balancers,
an external IP address would be provisioned to access the Service. On Minikube,
the `LoadBalancer` type makes the Service accessible through the `minikube service`

## 创建 Service
