Apache and passenger behave differently on Docker mac vs ubuntu
I’m experiencing some issues with containers running apache2 + passenger phusion + rails app when I deploy them on mac or linux.
I use the same image (based on ubuntu:14.04) pulled from the docker hub and the same run command
docker run -it -p 80:80 -p 443:443 -e RAILS_ENV=development --link pg my-image-name
On OSX 10.10.5, running docker 1.9.1, build a34a1d5 everything works fine.
On my production server ubuntu 14.04.3 LTS, running the same docker version, I get the following error
AH00035: access to / denied (filesystem path '/home/app/app') because search permissions are missing on a component of the path
Permissions are set with chmod 775 -R /home/app.
Here is passenger and apache version + configuration
Server version: Apache/2.4.7 (Ubuntu) Server built: Oct 14 2015 14:20:21 Phusion Passenger 5.0.22 <VirtualHost *:80> ServerName www.my-app.com DocumentRoot /home/app/app/public PassengerRuby /usr/bin/ruby RailsEnv development ErrorLog "/home/app/app/log/apache_error_log" CustomLog "/home/app/app/log/apache_access_log" common <Directory /home/app/app/public> AllowOverride all Options -MultiViews +FollowSymLinks +Indexes Require all granted Order allow,deny allow from all </Directory> </VirtualHost>
Any idea why I’m getting two different behaviours between OS X and Ubuntu running the same container?

As commented in issue 16741:
I think I’ve seen a similar issue, which was related to the aufs driver.
Fixed by using “devicemapper” instead of “aufs” thanks to this post:
“Switching Docker from aufs to devicemapper”
/etc/default/dockerto enable device mapper:
(save the images first)
# Use DOCKER_OPTS to modify the daemon startup options. DOCKER_OPTS="--storage-driver=devicemapper"
The OP Alberto Sabaini confirms it works:
I thought that Ubuntu LTS would be using device mapper as default, but by typing
docker info | grep Storage, I get
Storage Driver: aufsin both mac and Ubuntu.
The weird part is that my image spin fine on mac with aufs and on Ubuntu on device mapper.
