Docker / PHP / Apache - File permissions lost when created inside container - php

Question

i'm trying to set up a docker app with Apache and Php stack.
But when i create a new file inside my project container, the permissions losted because root user is connected by default.
How can I connect my host user ?
docker-compose.yml
version: '3'
services:
web:
container_name: web
build:
context: docker/web
volumes:
- ./app/:/var/www/app
- ./docker/web/apache/log:/var/log/apache2/app
working_dir: /var/www/app
ports:
- 80:80

RUN groupadd dev -g 1000
RUN useradd dev -g dev -d /home/dev -m
RUN echo '%dev ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers
I tried to create a dev user in my Dockerfile but not working.

Answer 1

And how about this?
# Add www-data to the '1000-group'
RUN usermod -u 1000 www-data

Answer 2

I solved the problem by adding my dev user to sudoers and then running apache2ctl in sudo.
FROM php:7.4-apache
RUN apt-get update && apt-get install -y \
sudo \
libfreetype6-dev \
libjpeg62-turbo-dev \
libpng-dev \

zip \
unzip \
&& docker-php-ext-configure gd --with-freetype --with-jpeg \
&& docker-php-ext-install -j$(nproc) gd \
&& docker-php-ext-install zip pdo pdo_mysql opcache \
&& apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
RUN rm /etc/localtime
RUN ln -s /usr/share/zoneinfo/Europe/Paris /etc/localtime
RUN "date"
RUN sed -ri -e 's!/var/www/html!/var/www!g' /etc/apache2/sites-available/*.conf
RUN sed -ri -e 's!/var/www/!/var/www!g' /etc/apache2/apache2.conf /etc/apache2/conf-available/*.conf
COPY php/php.ini /usr/local/etc/php/conf.d/app.ini
COPY apache/app.conf /etc/apache2/sites-available/000-default.conf
RUN groupadd dev -g 1000
RUN useradd dev -g dev -d /home/dev -m
RUN echo '%dev ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers
USER dev:dev
