Inside the `docker-compose.yml` file, add the necessary information which is tagged with curly braces ' `{  }` '.&#x20;

* **`IP`** -> The IP of the web service which you are running, such as on AWS EC2 Ubuntu, Lightsail instance or Azure Web services as an example.
* **`PORT`** -> The port which the app client-side is served at (e.g. Port 80).
* **`APPCODE`** -> Navigate to Developer dashboard > Applications > {App Name} > App Data, the Application code will be available there.
* **`HOSTNAME`** -> Can be found on the Developer dashboard, the boilerplate is the hostname  of the application: `https://<your_domain>/{APPCODE}`

{% hint style="info" %}
If the application container is pushed onto IndustryApps, the HOSTNAME is the Application ID.
{% endhint %}
