Allow Apache to write into locally synched docker volume

Question

Dockerfile

FROM php:5.6-apache
COPY config/php.ini /usr/local/etc/php/
RUN docker-php-ext-install mysql mysqli pdo pdo_mysql
RUN rm /var/log/apache2/access.log
RUN a2enmod rewrite
RUN a2enmod deflate
RUN a2enmod headers

docker-compose.yml

version: "2"
services:
  www:
    build: .
    ports: 
        - "8001:80"
    volumes:
        - ./www:/var/www/html/
    networks:
        - default

I have a folder within www that's called photos. It's at www/photos. I want to write files to it using my php upload function. I'm getting permission denied errors due to the fact that php-apache doesn't have write access to the volume. How to give apache write access?

Can you share which exact directory your php code is referring, as inside the docker container, the volume with be named as /var/www/html and not not /www — Aman Chhabra
The file writing to disc is at docker-container: /var/www/html/controllers/file.php — Tim Daubenschütz

Check the permissions of the directory on your host system, maybe guests do not have permissions to write. If necessary, change them using chmod:

chmod 766 -R your/directory/

Also, you can specify the permission to write inside your docker in a specified mounted volume by adding :rw (for read/write) at the end of the line:

- ./www:/var/www/html/:rw

Since this should be the default value it is not necessary to use it and should not be part of your problem.
