Why does php-fpm container crash when supervisor starts?

Question

PHP

There is such file docker-compose.yml

version: "2"
services:
  nginx:
    image: nginx:latest
    container_name: dev-chellange-nginx
    ports:
      - 7000:80
    volumes: 
      - ./docker/nginx:/etc/nginx/conf.d
      - ./src:/usr/share/nginx/html
    links:
      - php
  php:
    build: ./docker/php
    container_name: dev-chellange-php
    volumes: 
      - ./src:/var/www/html
      - ./docker/php/supervisor:/etc/supervisor/conf.d
    links:
      - mysql
      - redis
  mysql:
    image: mysql
    container_name: dev-chellange-mysql
    command: --default-authentication-plugin=mysql_native_password
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: dev_chellange
  redis:
    image: redis
    container_name: dev-chellange-redis

PHP container dockerfile

FROM php:7.4-fpm

CMD ["/usr/bin/supervisord"]

Worker supervisor configuration:

[program:queue-workers]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/html/application/artisan queue:work --sleep=3 --tries=3 --max-time=3600
autostart=true
autorestart=true
user=root
numprocs=5
redirect_stderr=true
stdout_logfile=/etc/supervisor/conf.d/queue-workers.log
stopwaitsecs=3600

The problem is the following. If you start the supervisor directly through the container terminal after doing docker-compose up , then everything works, the supervisor starts and the worker works correctly. But if you try to do this through the cmd directive in the dockerfile (as indicated in the example), then the container crashes after the docker-compose up command .
