General
=======

Are there any differences between native Docker and Docker Toolbox?
-------------------------------------------------------------------

Yes, read :ref:`howto_docker_toolbox_and_the_devilbox` to find out more.


.. _faq_data_dir_separated_by_version:

Why are mounted MySQL data directories separated by version?
------------------------------------------------------------

This is just a pre-caution. Imagine they would link to the same datadir.  You start the Devilbox
with mysql 5.5, create a database and add some data.  Now you decide to switch to mysql 5.7 and
restart the devilbox. The newer mysql version will probably upgrade the data leaving it unable to
start with older mysql versions.


Why are mounted PostgreSQL data directories separated by version?
-----------------------------------------------------------------

See: :ref:`faq_data_dir_separated_by_version`


Why are mounted MongoDB data directories separated by version?
--------------------------------------------------------------

See: :ref:`faq_data_dir_separated_by_version`


Why do the user/group permissions of log/ or cfg/ directories show 1000?
------------------------------------------------------------------------

Uid and Gid are set to 1000 by default. You can alter them to match the uid/gid of your current
user. Open the ``.env`` file and change the sections ``NEW_UID`` and ``NEW_GID``. When you start
up the devilbox, the PHP container will use these values for its user.

.. seealso:: :ref:`env_new_uid` and :ref:`env_new_gid`


Can I not just comment out the service in the .env file?
--------------------------------------------------------

No, don't do this. This will lead to unexpected behaviour (different versions will be loaded).
The ``.env`` file allows you to configure the devilbox, but not to start services selectively.


Are there any required services that must/will always be started?
-----------------------------------------------------------------

Yes. ``http`` and ``php`` will automatically always be started (due to dependencies inside
``docker-compose.yml``) if you specify them or not.


What PHP Modules are available?
-------------------------------

The Devilbox is a development stack, so it is made sure that a lot of PHP modules are available
out of the box in order to work with many different frameworks.

Available PHP modules can be seen at the PHP Docker image repository.

.. seealso:: https://github.com/devilbox/docker-php-fpm


Configuration
=============

.. Can I load custom PHP modules without rebuilding the Docker image?
.. ------------------------------------------------------------------
.. 
.. Yes, see :ref:`custom_php_modules`
.. 
.. 
.. Can I load custom Apache modules without rebuilding the Docker image?
.. ---------------------------------------------------------------------
.. 
.. Yes, see :ref:`custom_apache_modules`


Can I change the MySQL root password?
-------------------------------------

Yes, you can change the password of the MySQL root user. If you do so, you must also set the new
password in your ``.env`` file. See :ref:`env_mysql_root_password` for how to change this value.


Can I change php.ini?
---------------------

Yes, php.ini directives can be changed for each PHP version separately. See :ref:`php_ini`


Can I change my.cnf?
--------------------

Yes, my.cnf directives can be changed for each MySQL version separately. See :ref:`my_cnf`


Can I change the project virtual host domain ``.loc``?
------------------------------------------------------

Yes, the ``.env`` variable :ref:`env_tld_suffix` can be changed to whatever domain or subdomain
you want. See :ref:`env_tld_suffix`.

.. warning::
   Be aware not to use ``dev`` or ``localhost``. See :ref:`env_tld_suffix` for more details.


Can I just start PHP and MySQL instead of all container?
--------------------------------------------------------

Yes, every Docker container is optional. The Devilbox allows for selective startup. See
:ref:`start_the_devilbox`.


Do I always have to edit ``/etc/hosts`` for new projects?
---------------------------------------------------------

You need a valid DNS entry for every project that points to the Httpd server. As those records
don't exists by default, you will have to create them. However, the Devilbox has a bundled DNS
server that can automate this for you. The only thing you have to do for that to work is to add
this DNS server's IP address to your ``/etc/resolv.conf``.
See :ref:`setup_auto_dns` for detailed instructions.
