Answer a question

I know a very similar answer has already been dealt with here BUT in my case I am using an already made docker image (https://hub.docker.com/r/prestashop/prestashop/) and I don't think I can modify the Dockerfile

I think I need to execute this command echo "ServerName localhost" >> /etc/apache2/apache2.conf but I don't know how, idealy I would like to gather all the configurations in the docker-compose.yml file, here it is:

version: "3.7"

services:
  app:
    image: prestashop/prestashop:1.7
    ports:
      - 8080:80
    working_dir: /var/www/html
    volumes:
      - ./:/var/www/html
    environment:
      DB_SERVER: mysql
      MYSQL_USER: root
      MYSQL_PASSWORD: mypass123
      MYSQL_DB: prestashop

  mysql:
    image: mysql:5.7
    environment: 
      MYSQL_ROOT_PASSWORD: mypass123
      MYSQL_DATABASE: prestashop

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    ports:
      - 8081:80
    environment:
      MYSQL_ROOT_PASSWORD: mypass123
      MYSQL_DATABASE: prestashop

When I run docker-compose up I get this "error"

phpmyadmin_1 | AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.20.0.3. Set the 'ServerName' directive globally to suppress this message

app_1 | AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.20.0.4. Set the 'ServerName' directive globally to suppress this message

Any idea ?

Thank you

You can modify the container by creating the following Dockerfile

FROM prestashop/prestashop:1.7

RUN echo "ServerName localhost" >> /etc/apache2/apache2.conf

and modify the docker-compose.yml

...
services:
  app:
    build: .
    ports:
      - 8080:80
    working_dir: /var/www/html
...
