Universal Control Plane.

|
|
|
|
With Docker Universal Control Plane you can deploy applications from the
|
|
UI using `docker-compose.yml` files. In this example, we're going to deploy a
|
|
WordPress application.
|
|
|
|
## Deploy WordPress
|
|
|
|
In your browser, **log in** to UCP, and navigate to the **Applications** page.
|
|
There, click the **Deploy compose.yml** button, to deploy a new application.
|
|
|
|
{: .with-border}
|
|
|
|
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.
|
|
|
|
```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:
|
|
```
|
|
|
|
Name the application 'wordpress', and paste the docker-compose.yml definition.
|
|
You can also upload a docker-compose.yml file from your machine, by clicking on
|
|
the 'Upload an existing docker-compose.yml' link.
|
|
|
|
{: .with-border}
|
|
|
|
Click the **Create** button, to create the WordPress application.
|
|
|
|
Once UCP deploys the WordPress application, you can
|
|
**click on the wordpress_wordpress_1** container, to see its details.
|
|
|
|
{: .with-border}
|
|
|
|
In the container details page, search for the **Ports** the container is
|
|
exposing.
|
|
|
|
{: .with-border}
|
|
|
|
In this example, WordPress can be accessed at `172.31.18.152:8000`.
|
|
Navigate to this address in your browser, to start using the WordPress app you
|
|
just deployed.
|
|
|
|
{: .with-border}
|
|
|
|
|
|
## Limitations
|
|
|
|
There are some limitations when deploying docker-compose.yml applications from
|
|
the UI. You can't reference any external files, so the following Docker
|
|
Compose keywords are not supported:
|
|
|
|
* build
|
|
* dockerfile
|
|
* env_file
|
|
|
|
{: .with-border}
|
|
|
|
To overcome these limitations, you can
|
|
[deploy your apps from the CLI](deploy-app-cli.md).
|
|
|
|
Also, UCP doesn't store the compose file used to deploy the application. You can
|
|
use your version control system to persist that file.

|
