Docker /user/sbin/apache2ctl: not found

This issue is not a duplicate of “/bin/sh: 1: “apache2ctl”,: not found” in docker

This is a simple docker file I used for laravel framework in a ubuntu operating system.

version : '3'

services:
  web: 
    container_name: ${APP_NAME}_web
    build:
      context: ./docker/web
    ports:
      - 9000:80
    volumes:
      - ./:/var/www/app

And this is the docker file located in docker/web

FROM php:7.2.10-apache-stretch

RUN apt-get update -yqq && 
    apt-get install -y apt-utils zip unzip && 
    apt-get install -y nano && 
    apt-get install -y libzip-dev libpq-dev && 
    a2enmod rewrite && 
    docker-php-ext-install pdo_pgsql && 
    docker-php-ext-install pgsql && 
    docker-php-ext-configure zip --with-libzip && 
    docker-php-ext-install zip && 
    rm -rf /var/lib/apt/lists/*

RUN php -r "readfile('http://getcomposer.org/installer');"|php -- --install-dir=/usr/bin --filename=composer

COPY Default.conf /etc/apache2/sites-enabled/000-default.conf

WORKDIR /var/www/app

EXPOSE 80

CMD ['/usr/sbin/apache2ctl', '-D', 'FOREGROUND']

When I run this command

sudo docker-compose up

Terminal Output is this error

Starting Docker_Laravel_web ... done
Attaching to Docker_Laravel_web
Docker_Laravel_web | /bin/sh: 1: [/usr/sbin/apache2ctl,: not found
Docker_Laravel_web exited with code 127

Need some help to fix this,

    It looks like didn’t install apache application

    you should add 1 more command line in RUN

    apt-get install -y apache2 &&

    The Dockerfile syntax, where it has things that look like JSON lists, isn’t actually JSON, and is fairly picky about its quoting. In particular, in your final line

    CMD ['/usr/sbin/apache2ctl', '-D', 'FOREGROUND']

    you must use double quotes

    CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]

    otherwise Docker interprets it as the “run a shell on this command” form, which is why you see the [ and , in your error message.
