In this Kubernetes YAML file, there are two objects, separated by the `---`:
- A Deployment, describing a scalable group of identical pods. In this case,
you'll get just one replica, or copy of your pod. That pod, which is
described under `template`, has just one container in it. The container is
created from the image built by GitHub Actions in [Configure CI/CD for your
PHP application](configure-ci-cd.md).
- A NodePort service, which will route traffic from port 30001 on your host to
port 80 inside the pods it routes to, allowing you to reach your app
from the network.
To learn more about Kubernetes objects, see the [Kubernetes documentation](https://kubernetes.io/docs/home/).
## Deploy and check your application
1. In a terminal, navigate to the `docker-php-sample` directory
and deploy your application to Kubernetes.
```console
$ kubectl apply -f docker-php-kubernetes.yaml
```
You should see output that looks like the following, indicating your Kubernetes objects were created successfully.
```text
deployment.apps/docker-php-demo created
service/php-entrypoint created
```
2. Make sure everything worked by listing your deployments.
```console
$ kubectl get deployments
```
Your deployment should be listed as follows:
```text
NAME READY UP-TO-DATE AVAILABLE AGE
docker-php-demo 1/1 1 1 6s
```
This indicates all of the pods are up and running. Do the same check for your services.
```console
$ kubectl get services
```
You should get output like the following.
```text
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 7d22h
php-entrypoint NodePort 10.111.101.229 <none> 80:30001/TCP 33s
```
In addition to the default `kubernetes` service, you can see your `php-entrypoint` service. The `php-entrypoint` service is accepting traffic on port 30001/TCP.
3. Open a browser and visit your app at
[http://localhost:30001/hello.php](http://localhost:30001/hello.php). You
should see your application.
4. Run the following command to tear down your application.
```console
$ kubectl delete -f docker-php-kubernetes.yaml
```
## Summary
