Error at step 7 with Symfony application

[Benjamin Lazarecki]

Hi,

First of all, I would like to thanks you for this awesome tool, that makes docker fun and easy to use!

I have an issue with this configuration

.gaudi.yml

applications:
    front:
        type: apache
        links: [app]
        ports:
            80: 80
        volumes:
            .: /var/www
        custom:
            fastCgi: app
            documentRoot: /var/www/web
            modules: [rewrite]

    app:
        type: php-fpm
        links: [db]
        ports:
            9000: 9000
        volumes:
            .: /var/www

    db:
        type: mysql
        ports:
            3306: 3306
        after_script: mysql -e "CREATE DATABASE symfony CHARACTER SET utf8 COLLATE utf8_general_ci;" -uroot
        volumes:
            .gaudi/mysql: /var/lib/mysql

The issue is:

Step 7 : RUN grep -v rootfs /proc/mounts > /etc/mtab
 ---> Running in da791898e3a0
grep: write error
2014/04/24 22:25:48 The command [/bin/sh -c grep -v rootfs /proc/mounts > /etc/mtab] returned a non-zero code: 2

Here the full log detail

The command docker images give me this:

Any idea ?

Thanks!

Thanks for the feedback.
I've removed the RUN grep -v rootfs /proc/mounts > /etc/mtab from the MySQL Dockerfile.
This was an attempt to fix user rights on the shared mysql data folder.
After some investigations, the issue doesn't come from the container but with my Vagrant configuration
