Having trouble on Docker trying to install Moodle through php8.5.3-apache image.

Here is my Dockerfile :

FROM php:8.5.3-apache
WORKDIR /var/www/html/

# COPY ./moodle.conf /etc/apache2/conf-available/moodle.conf to set up the Apache configuration for Moodle. This file should contain the necessary directives to serve the Moodle application correctly.
COPY ./moodle_listener.conf /etc/apache2/moodle_listener.conf
COPY ./moodle_listeners.conf /etc/apache2/sites-available/moodle_listeners.conf

# Clone Moodle 5.1+ et configure la structure

    cd /var/www/html/moodle && \ 
    git clone -b MOODLE_501_STABLE git://git.moodle.org/moodle.git . && \
    chown -R root /var/www/html/moodle/ && \

    chown -R www-data:www-data /var/www/html/moodledata && \
    chmod -R 0777 /var/www/html/moodledata



# Ensure the default site is enabled
RUN ln -sf /etc/apache2/sites-available/moodle_listeners.conf /etc/apache2/sites-enabled/

CMD ["apache2ctl", "-D", "FOREGROUND"]

EXPOSE 8080

Here is the moodle_listeners.conf :

Include /etc/apache2/moodle_listener.conf

And the moodle_listener.conf is there, copied from the Moodle Code Restructure article.

This is the error code when I docker run -p 8080:8080 --name moodle_setup moodle5.1 :

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

I try some things on the web but nothing concluant. Thanks for help. The repo is here.
