Symfony VAR directory still root with docker - docker

Question

I'm trying to setup my project with Docker but I'm facing an issue...
This is my docker-compose:
version: '3.8'
services:
back:
container_name: ${BACK_CONTAINER_NAME}
build:
context: ./back
target: ${TARGET}
args:
USER_ID: ${USER_ID:-0}
GROUP_ID: ${GROUP_ID:-0}
user: ${USER_ID:-0}:${GROUP_ID:-0}
environment:
- SOME_ENVS
volumes:
- ./back:/srv/app
- ./back/opcache.ini:/usr/local/etc/php/conf.d/opcache.ini
networks:
- lan
networks:
lan:
name: ${NETWORK_NAME}
volumes:
db_data_prod:
Dockerfile:
FROM php:8.1.11-fpm as base
ARG USER_ID
ARG GROUP_ID
RUN addgroup --gid $GROUP_ID user
RUN adduser --disabled-password --gecos '' --uid $USER_ID --gid $GROUP_ID user
RUN apt update --fix-missing \
&& apt install -y zlib1g-dev libonig-dev iputils-ping libzip-dev libicu-dev zip libpq-dev
COPY docker-entrypoint.sh /usr/local/bin/docker-entrypoint
RUN chmod +x /usr/local/bin/docker-entrypoint
ENTRYPOINT ["docker-entrypoint"]
CMD ["php-fpm"]
WORKDIR /srv/app
RUN docker-php-ext-install pdo pdo_pgsql mbstring zip
COPY . .
# Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
VOLUME /srv/app/var/
RUN PATH=$PATH:/srv/app/vendor/bin:bin
FROM base as dev
RUN composer install --prefer-dist --no-autoloader --no-scripts --no-progress
RUN pecl install xdebug
RUN docker-php-ext-enable mbstring xdebug
USER user
FROM base as prod
RUN docker-php-ext-install opcache
RUN composer install --prefer-dist --no-dev --no-progress --no-scripts --no-interaction
USER user
And the entrypoint:
#!/bin/sh
set -e
# first arg is `-f` or `--some-option`
if [ "${1#-}" != "$1" ]; then
set -- php-fpm "$#"
fi
if [ "$1" = 'php-fpm' ] || [ "$1" = 'php' ] || [ "$1" = 'bin/console' ]; then
if [ "$APP_ENV" != 'prod' ]; then
composer install --prefer-dist --no-progress --no-interaction
fi
if grep -q DATABASE_URL= .env; then
echo "Waiting for database to be ready..."
ATTEMPTS_LEFT_TO_REACH_DATABASE=60
until [ $ATTEMPTS_LEFT_TO_REACH_DATABASE -eq 0 ] || DATABASE_ERROR=$(php bin/console dbal:run-sql -q "SELECT 1" 2>&1); do
if [ $? -eq 255 ]; then
# If the Doctrine command exits with 255, an unrecoverable error occurred
ATTEMPTS_LEFT_TO_REACH_DATABASE=0
break
fi
sleep 1
ATTEMPTS_LEFT_TO_REACH_DATABASE=$((ATTEMPTS_LEFT_TO_REACH_DATABASE - 1))
echo "Still waiting for database to be ready... Or maybe the database is not reachable. $ATTEMPTS_LEFT_TO_REACH_DATABASE attempts left."
done
if [ $ATTEMPTS_LEFT_TO_REACH_DATABASE -eq 0 ]; then
echo "The database is not up or not reachable:"
echo "$DATABASE_ERROR"
exit 1
else
echo "The database is now ready and reachable"
fi
if [ "$( find ./migrations -iname '*.php' -print -quit )" ]; then
php bin/console doctrine:migrations:migrate --no-interaction
fi
fi
fi
exec docker-php-entrypoint "$#"
So, when I'm running the container, all the folders are set with the right user (user..) but only the /srv/app/var folder still root... and the app crashs cause of this.
Anyone have an idea?
Thanks
