Properly push Docker image with other images

Question

I made a PHP app and want to make a Docker image out of it. For my app to work, I need PHP-apache, MySQL, and PhpMyAdmin.

When I run docker-compose up, everything works fine.

So, I did docker ps -a and got:

CONTAINER ID   IMAGE                            COMMAND                  CREATED         STATUS          PORTS                               NAMES

ff13a69f0fde   mysql                            "docker-entrypoint.s…"   9 minutes ago   Up 27 seconds   33060/tcp, 0.0.0.0:9906->3306/tcp   db

I want to push my project to Docker Hub, but I am not sure how to do it. When I commit and push docker2-php-apache-environment(fa19aa03b658) and pull the image on a different machine, I am missing MySql and PhpMyAdmin.

Is it possible to push the whole project so that when somebody pulls and runs the image, everything works?

I made docker-compose.yml which looks like this:

version: '3.8'
services:
    php-apache-environment:
        container_name: php-apache
        build:
            context: ./php
            dockerfile: Dockerfile
        depends_on:
            - db
        volumes:
            - ./php/src:/var/www/html/ 
        ports:
            - 8000:80
    db:
        container_name: db
        image: mysql
        restart: always
        environment:
            MYSQL_ROOT_PASSWORD: 12345
            MYSQL_DATABASE: turisticka_agencija
        ports:
            - "9906:3306"
    phpmyadmin:
      image: phpmyadmin/phpmyadmin
      ports:
          - '8080:80'
      restart: always
      environment:
          PMA_HOST: db
      depends_on:
          - db

Dockerfile looks like this:

FROM php:8.0-apache
RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
RUN apt-get update && apt-get upgrade -y

# Install build dependencies and the OPcache extension
RUN apk add --no-cache $PHPIZE_DEPS \
    && docker-php-ext-install opcache \
    && apk del $PHPIZE_DEPS

# Copy the opcache.ini into your Docker image    
COPY opcache.ini /usr/local/etc/php/conf.d/opcache.ini

# Run your application
CMD php-fpm
