With Docker Universal Control Plane you can deploy your apps from the CLI,
using Docker Compose. In this example we're going to deploy a WordPress
application.

## Get a client certificate bundle

Docker UCP secures your Docker swarm with role-based access control, so that only
authorized users can deploy applications. To be able to run
Docker commands on a swarm managed by UCP, you need to authenticate your
requests using client certificates.

[Learn how to set your CLI to use client certificates](../access-ucp/cli-based-access.md).

## Deploy WordPress

The WordPress application we're going to deploy is composed of two services:

* wordpress: The service that runs Apache, PHP, and WordPress.
* db: A MariaDB database used for data persistence.

After setting up your terminal to authenticate using client certificates,
create a file named `docker-compose.yml` with the following service definition:

```none
version: '2'

services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: wordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_PASSWORD: wordpress
volumes:
    db_data:
```

In your command line, navigate to the place where you've created the
`docker-compose.yml` file and run:

```bash
$ docker-compose --project-name wordpress up -d
```

Test that the WordPress service is up and running, and find where you can
reach it.

```bash
$ docker-compose --project-name wordpress ps

Name                       Command               State             Ports
------------------------------------------------------------------------------------------
wordpress_db_1          docker-entrypoint.sh mysqld      Up      3306/tcp                   
wordpress_wordpress_1   docker-entrypoint.sh apach ...   Up      172.31.18.153:8000->80/tcp
```

In this example, WordPress can be accessed at 172.31.18.153:8000. Navigate to
this address in your browser, to start using the WordPress app you just
deployed.
