php-fpm is not running on docker-compose up

[ghost]

I am running a slightly modified version of the generated files from phpdocker.io and php-fpm won't start on docker-compose up

There are no logs being generated, as it just looks like php-fpm doesn't start.

docker-compose.yml:

version: "3.1"
services:

    postgres:
      image: postgres:11.1-alpine
      container_name: sgn-postgres
      working_dir: /application
      volumes:
        - .:/application
        - ./docker/postgres/:/docker-entrypoint-initdb.d/
      environment:
        - POSTGRES_USER=sgn
        - POSTGRES_PASSWORD=sgn
        - POSTGRES_DB=sgn
      ports:
        - "5432:5432"
      restart: always

    webserver:
      image: nginx:alpine
      container_name: sgn-webserver
      working_dir: /application
      volumes:
          - .:/application
          - ./docker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
      ports:
       - "80:80"
      restart: always

    php-fpm:
      build: docker/php-fpm
      container_name: sgn-php-fpm
      working_dir: /application
      volumes:
        - .:/application
        - ./docker/php-fpm/php-ini-overrides.ini:/etc/php/7.4/fpm/conf.d/99-overrides.ini
      restart: always

Dockerfile inside /php-fpm/:

Removing Cron commands made this work again.

If you need cron commands, you can simply run another php container - in fact this would be the preferred method. You can use phpdockerio/php74-cli for that (no FPM on that one)

[ghost]

Are there any way to include cron in the php-fpm container?
Having a container just for CLI looks like a waste to me.

Docker best practices are to have one container per function.
