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 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.
|
|
|
|
Once UCP deploys the WordPress application, you can
|
|
**click on the wordpress_wordpress_1** container, to see its details.
|
|
|
|
|
|
|
|
In the container details page, search for the **Ports** the container is
|
|
exposing.
|
|
|
|
|
|
|
|
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. You can't
|
|
reference any external files, so the following Docker Compose keywords are not
|
|
supported:
|
|
|
|
* build
|
|
* dockerfile
|
|
* env_file
|
|
|
|
|
|
|
|
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.
|
|
