Thank you for sharing your Docker compose file. I find it particularly helpful how you include different settings for PHP. Allow me a few comments:

• According to the WordPress documentation, define('ENVIRONMENT', 'local'); should be replaced by define('WP_ENVIRONMENT', 'local'); (or development, staging, and productionrespectively). At least if you want to use a plugin like Display Environment Type for your development website.

• To use the plugin Intellephense in VS Code, I only use

volumes:
  - ./wordpress:/var/www/html
  - ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
  - ./error-logging.ini:/usr/local/etc/php/conf.d/error-logging.ini

instead of the volumes you use for themes, plugins and mu-plugins. This way I can load all files of the WordPress installation into VS Code, which e.g. makes it easy to look up core function definitions.

• I am also missing a setup to use WordPress Coding Standards with PHP Code Sniffer and wonder, of that may be included into the Docker file.
