File permissions lost when it created inside container – Phpmyadmin

I have created a docker app with Symfony/PHP, Apache and Mysql stack.
When i run the php container, i’m automatically connected as root user.
So when i create a new file inside the container, it’s created as read-only mode because of user root and group root.
I always have to change the permissions to edit it in local side.
How can I fix the problem ? Is it possible to connect to container as my local user directly ?

My dockerfile:

FROM php:7.2-fpm
RUN apt-get update && apt-get install -y 
        libfreetype6-dev 
        libjpeg62-turbo-dev 
        libpng-dev 
    && docker-php-ext-install -j$(nproc) iconv 
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ 
    && docker-php-ext-install -j$(nproc) gd 
    && docker-php-ext-install zip 
    && docker-php-ext-install mysqli pdo pdo_mysql

RUN curl -sSk https://getcomposer.org/installer | php -- --disable-tls && 
   mv composer.phar /usr/local/bin/composer

RUN apt-get install -y git

My docker-compose file:
