Assuming you have already registered a DNS record for your application pointing to the external load-balancer fronting the `infra` nodes, you should be able to access your application using the URL.You can also scale the docker demo deployment to test how ingress correctly routes traffic to all the backend pods!

## Check your deployment
The `default-http-backend` provides a simple service that serves a 404 page
at `/` and serves 200 on the `/healthz` endpoint.
1. Navigate to the **Controllers** page and confirm that the
**default-http-backend** and **nginx-ingress-controller** objects are
scheduled.
> Scheduling latency
>
> It may take several seconds for the HTTP backend and the ingress controller's
> `Deployment` and `ReplicaSet` objects to be scheduled.

2. When the workload is running, navigate to the **Load Balancers** page
and click the **ingress-nginx** service.

3. In the details pane, click the first URL in the **Ports** section.
A new page opens, displaying `default backend - 404`.
## Check your deployment from the CLI
From the command line, confirm that the deployment is running by using
`curl` with the URL that's shown on the details pane of the **ingress-nginx**
service.
```bash
curl -I http://<ucp-ip>:<ingress port>/
```
This command returns the following result.
```
HTTP/1.1 404 Not Found
Server: nginx/1.13.8
```
Test the server's health ping service by appending `/healthz` to the URL.
```bash
curl -I http://<ucp-ip>:<ingress port>/healthz
```
This command returns the following result.
```
HTTP/1.1 200 OK
Server: nginx/1.13.8
```
