1. General

Are there any differences between Linux, Windows and OSX?

Yes, have a look at OS to read up about the differences.

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: Why are mounted MySQL data directories separated by version?

Why are mounted MongoDB data directories 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.

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.

apc, apcu, bcmath, bz2, calendar, Core, ctype, curl, date, dom, ereg, exif, fileinfo, filter, ftp, gd, gettext, gmp, hash, iconv, igbinary, imagick, imap, intl, json, ldap, libxml, magickwand, mbstring, mcrypt, memcache, memcached, mhash, mongodb, msgpack, mysql, mysqli, mysqlnd, openssl, pcntl, pcre, PDO, pdo_mysql, pdo_pgsql, pdo_sqlite, pgsql, phalcon, Phar, posix, pspell, readline, recode, redis, Reflection, session, shmop, SimpleXML, soap, sockets, SPL, sqlite3, standard, sysvmsg, sysvsem, sysvshm, tidy, tokenizer, uploadprogress, wddx, xdebug, xml, xmlreader, xmlrpc, xmlwriter, xsl, Zend OPcache, zip, zlib

There will however be slight differences between the versions and especially with HHVM. To see the exact bundled modules for each version visit the corresponding docker repositories on Github:

PHP 5.4 | PHP 5.5 | PHP 5.6 | PHP 7.0 | PHP 7.1 | PHP 7.2 | HHVM

2. Configuration

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 Configure for how to change the values.

Can I add other PHP Modules?

Yes, if there are any PHP modules you require that are not yet available in the PHP Docker container, you can install it during run-time, or create your own container. See Hacking for more information.

Can I change php.ini?

Yes, php.ini directives can be changes on a per PHP version base. Go to ./cfg/ inside devilbox git diretory. There you will find configuration directories for each php version. Just put a *.ini file there and restart the devilbox.

Can I change my.cnf?

Yes, my.cnf directives can be changes on a per MySQL version base. Go to ./cfg/ inside devilbox git diretory. There you will find configuration directories for each MySQL version. Just put a *.cnf file there and restart the devilbox.

Can I switch HHVM between PHP 5.6 and PHP 7 mode?

Yes, this can be done by adding a *.ini file to ./cfg/hhvm-latest/ with the following content to disable PHP 7 mode:

hhvm.php7.all = 0

The default is to use PHP 7 mode.

Can I change the project virtual host domain .loc?

Yes, the .env variable TLD_SUFFIX can be adjusted with whatever domain or subdomain your require. A few examples to get you started:

Project folder	TLD_SUFFIX	Project URL
project1	loc	http://project1.loc
project1	local	http://project1.local
project1	dev	http://project1.dev
project1	work.loc	http://project1.work.loc

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

Yes, every Docker container is optional. The devilbox allows for selective startup. See Run: selective start for more detail.

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 Configure: AutoDNS for instructions.
