Issue with Composer CLI Interpreter

Hello,

I am having a slight issue with the Composer CLI remote interpreter within one of my projects.

As a bit of additional information, I am running my application inside a Docker network where each container is given an alias hostname (i.e. redis, mysql etc..):

version: '3'
services:

  # Application
  app:
    build:
      context: ./
      dockerfile: Dockerfile.dev
    working_dir: /var/www/html
    volumes:
      - ./webroot:/var/www/html
    networks:
      - laravel

  # Web Server
  nginx:
    image: nginx:1.19.2-alpine
    ports:
      - "8005:80"
    volumes:
      - ./webroot:/var/www/html
      - ./docker/vhost.conf:/etc/nginx/conf.d/default.conf
    depends_on:
      - app
      - mysql
      - redis
    networks:
      - laravel

  # MySQL Database
  mysql:
    image: mysql:8.0.21
    restart: unless-stopped
    tty: true
    ports:
      - "3306:3306"
    volumes:
      - db-data:/var/lib/mysql
    environment:
      MYSQL_DATABASE: homestead
      MYSQL_USER: homestead
      MYSQL_PASSWORD: secret
      MYSQL_ROOT_PASSWORD: secret
    networks:
      - laravel

  # Redis Database
  redis:
    image: redis:5.0.6
    restart: unless-stopped
    ports:
      - "6379:6379"
    volumes:
      - redis-data:/data
    command: [ "redis-server", "--appendonly", "yes" ]
    networks:
      - laravel

networks:
  laravel:

volumes:
  db-data:
  redis-data:

When running commands directly from the terminal, I am able to run scripts such as docker-compose exec app composer run post-autoload-dump and everything will work perfectly.

However when I use the built in run configuration screen, it just won't work at all. I get the following issue suggesting it can't resolve the alias hostname redis.

In my mind both are using the composer instance remotely installed within the docker container, so I don't see any reason why there would be any difference. I am wondering if I have done anything incorrectly when setting up composer / docker in the settings:

In particular I am wondering if my network mode / extra host settings need to be configured differently. Any help anyone could offer would be really appreciated!
