I'm building a Docker image for my Symfony
app and I need to give permission to apache server to write into cache and log folders
#Dockerfile
FROM php:7-apache
RUN apt-get update \
&& apt-get install -y libicu-dev freetds-common freetds-bin unixodbc \
&& docker-php-ext-install intl mbstring \
&& a2enmod rewrite
COPY app/php.ini /usr/local/etc/php/
COPY app/apache2.conf /etc/apache2/apache2.conf
COPY ./ /var/www/html
RUN find /var/www/html/ -type d -exec chmod 755 {} \;
RUN find /var/www/html/ -type f -exec chmod 644 {} \;
RUN chmod -R 777 /var/www/html/app/cache /var/www/html/app/logs
When I build this image with docker build -t myname/symfony_apps:latest .
and run the container with docker run -p 8080:80 myname/symfony_apps:latest
.
Apache log is flooded by permission denied errors , the strange thing that I've checked with ls -a
and permissions are fine. and when I run chmod from container's bash , apache permission issues are gone and the app works well
The situation
Running chmod commands from dockerfile: permissions are changed but apache still complains about permission denied.
Running chmod same commands with bash inside the container: permissions are changed and my app is running
Any idea , Am I missing something, maybe I should add root user somewhere in the Dockerfile ?

I had the same issue and it seems that there is some bug in docker or overlay2 if directory content is created in one layer and its permissions are changed in other.
As a workaround you could copy sources to temporary directory:
And then move it to
/var/www/html
and setup permissions (in oneRUN
command):Also I created GitHub issue.
