+# Deploy an app from the UI
+
+With Docker Universal Control Plane you can deploy applications from the
+UI. You can define your application on the UI, or import an existing
+docker-compose.yml file.
+
+In this example, we're going to deploy a WordPress application.
+
+## Deploy WordPress
+
+On your browser, **log in** to UCP, and navigate to the **Applications** page.
+There, click the **Compose Application** button, to deploy a new application.
+

+
+The application WordPress application we're going to deploy is composed of
+two services:
+
+* wordpress: The container that runs Apache, PHP, and WordPress.
+* db: A MariaDB database used for data persistence.
+
+<!-- would be better if this was a docker-compose v2 file-->
+
+```yml
+wordpress:
+  image: wordpress
+  links:
+    - db:mysql
+  ports:
+    - 8080:80
+
+db:
+  image: mariadb
+  environment:
+    MYSQL_ROOT_PASSWORD: example
+```
+
+Copy-paste the application definition to UCP, and name it 'wordpress'.
+You can also upload a docker-compose.yml file from your machine, by clicking on
+the 'Upload an existing docker-compose.yml' link.
+

+
+Click the **Create** button, to create the WordPress application.
+
+Docker UCP deployed the WordPress application to the cluster. You can
+**click on the wordpress_wordpress_1** container, to see its details.
+
+![](../images/deploy-app-ui-3.png)
+
+In the container details page, search for the **Ports** the container is
+exposing.
+
+![](../images/deploy-app-ui-4.png)
+
+In this example, WordPress can be accessed at `192.168.99.106:8080`.
+Navigate to this address in your browser, to start using the WordPress app you
+just deployed.

+
+
+## Limitations
+
+There are some limitations when deploying application on the UI. The following
+Docker Compose keywords are not supported:
+
+* build
+* dockerfile
+* env_file
+
+![](../images/deploy-app-ui-6.png)
+
+To overcome these limitations, you can
+[deploy your apps from the CLI](deploy-app-cli.md).
