# 01b) The Docker Compose example

### The Docker Compose Example

1. To install Pterodactyl, you should use the `docker-compose.pt.yml` example that I made. It's just a bundled version of the official Pterodactyl Docker images. It includes both the Panel and Wings in one docker-compose file.
2. First, we need to create the `docker-compose.pt.yml` example. I'm going to put mine in this directory, since this is what I created back in the [beginning of this guide](https://guides.engels.zip/docker-and-compose-setup/02-cosmos-server-setup).

```bash
nano /opt/docker-all/docker-compose.pt.yml
```

3. You should use this `docker-compose.pt.yml` example, but remember to edit out the parts, that says `!!! CHANGE ME !!!` or something similar.

{% hint style="warning" %}
**Remember** to also change the `APP_URL`.\
In my case, the subdomain `pt-panel.engels.zip` is used. For the sake of simplicity, I recommend you keep the `pt-panel`as your subdomain.
{% endhint %}

```yaml
version: "3.9"
name: pt-stack
x-common:
  pt-database: &db-environment
    # Do not remove the "&db-password" from the end of the line below, it is important
    # for Panel functionality.
    MYSQL_PASSWORD: &db-password "!!Change This To Your Own Password!!"
    MYSQL_ROOT_PASSWORD: "!!Change This To A Different Password!!"
  pt-panel: &panel-environment
    APP_URL: "https://pt-panel.ChangeThisToYourDomain.com"
    # A list of valid timezones can be found here: http://php.net/manual/en/timezones.php
    APP_TIMEZONE: "Europe/Berlin"
    APP_SERVICE_AUTHOR: "your@email.com"
    # Uncomment the line below and set to a non-empty value if you want to use Let's Encrypt
    # to generate an SSL certificate for the Panel.
