+
+You can deploy and monitor your services from the UCP web UI. In this example
+we'll deploy an NGINX web server, and make it accessible on port `8000`.
+
+Navigate to the **UCP web UI**, click the **Resources** tab, and choose
+**Services**.

+Click the **Create a Service** button to deploy the NGINX service.

+
+Fill-in the following fields:
+
+| Field         | Value |
+|:--------------|:------|
+| Service name  | nginx |
+| Image name    | nginx |
+| Internal port | 80    |
+| Public port   | 8000  |
+

+
+Once you've specified the service image and ports, click **Deploy now** to
+deploy the service into a node in the UCP cluster.
+
+Once the service is up and running, you'll be able to see the default NGINX
+page, by going to `http://<node-ip>:8000`.

+
+## Deploy from the CLI
+
+You can also deploy the same service from the CLI. Once you've set up your
+[UCP client bundle](../access-ucp/cli-based-access.md), run:
+
+```none
+docker service create --name nginx \
+  --publish 8000:80 \
+  --label com.docker.ucp.access.owner=<your-username> \
+  nginx
+```
