Docker and running a queue (supervisor)

I need a little help with Docker because I can't find a solution. I'm trying to make a Laravel Queue work (running a supervisor).

My docker-compose.yml containing 3 Laravel applications looks something like this:

services:


  mysql:
    image: mysql:8


  basket-api:
    build:
      context: .
      dockerfile: Services/Basket/Basket.API/Dockerfile
    depends_on:
      - mysql


  catalog-api:
    build:
      context: .
      dockerfile: Services/Catalog/Catalog.API/Dockerfile
    depends_on:
      - mysql


  ordering-api:
    build:
      context: .
      dockerfile: Services/Ordering/Ordering.API/Dockerfile
    depends_on:
      - mysql

Then I have 3 Docker files, which look like this:

FROM php:7.4-fpm-alpine

RUN apk --no-cache add \
php7 \
php7-fpm \
php7-pdo \

...
...
...

RUN php7 -r "copy('http://getcomposer.org/installer', 'composer-setup.php');" && \
php7 composer-setup.php --install-dir=/usr/bin --filename=composer && \

COPY /Services/Basket/Basket.API /src
WORKDIR /src

RUN composer update

ENTRYPOINT ["sh", "./start.sh"]

Each of the 3 Laravel apps need to have working Queue - how do I add/run a supervisor and set it up?
