Way to integrate GD or Imagick extensions with docker compose

[WraShadow]

1. What did you do? If possible, provide a simple script for reproducing the error.

   
   I setup openswoole using docker-compose and I was trying to implement a image manipulation library but they seem to require either GD or Imagick, but I cannot seem to find a way to activate the extension.

2. What did you expect to see?

No error

3. What did you see instead?

ImageMagick module not available with this PHP installation. The same happens with GD.

4. What version of OpenSwoole are you using (show your `php --ri openswoole`)?

openswoole/swoole:4.11-php8.1

You can also try the following OpenSwoole support channels:

* [Documentation](https://openswoole.com/docs) - Documentation for Open Swoole
* [Slack](https://goo.gl/forms/wooTTDmhbu30x4qC3) - Slack channel of Open Swoole
* [Discord](https://discord.gg/5QC57RNPpw) - Discord server of Open Swoole

Is there anything else I can provide to help?

Create a custom Dockerfile and use that in docker-compose.yml.

FROM openswoole/swoole:4.11-php8.1

# Enable extensions
RUN apt-get update && apt-get install -y --no-install-recommends libpng-dev \
    && docker-php-ext-install gd

swoole5:
        restart: unless-stopped
        build:
            context: [path-to-dockerfile]
            dockerfile: ./Dockerfile

Thank you. It worked.
