Change container versions
One of the core concepts of the Devilbox is to easily change between different versions of a specific service.

Change PHP version
Stop the Devilbox
Shut down the Devilbox in case it is still running:
# Navigate to the Devilbox directory
host> /home/user/devilbox
# Stop all container
host> docker-compose stop
Edit the .env
file
Open the .env
file with your favourite editor and navigate to the PHP_SERVER
section. It will look something like this:
#PHP_SERVER=5.4
#PHP_SERVER=5.5
#PHP_SERVER=5.6
#PHP_SERVER=7.0
PHP_SERVER=7.1
#PHP_SERVER=7.1
As you can see, all available values are already there, but commented. Only one is uncommented. In this example it is 7.1
, which is the PHP version that will be started, once the Devilbox starts.
To change this, simply uncomment your version of choice and save this file. Do not forget to comment (disable) any other version.
In order to enable PHP 5.5, you would change the .env
file like this:
#PHP_SERVER=5.4
PHP_SERVER=5.5
#PHP_SERVER=5.6
#PHP_SERVER=7.0
#PHP_SERVER=7.1
#PHP_SERVER=7.1
Start the Devilbox
Now save the file and you can start the Devilbox again.
# Navigate to the Devilbox directory
host> /home/user/devilbox
# Stop all container
host> docker-compose up php httpd bind
start_the_devilbox
Gotchas
If two versions are uncommented, always the last one takes precedence.
Consider this .env
file:
#PHP_SERVER=5.4
PHP_SERVER=5.5
#PHP_SERVER=5.6
PHP_SERVER=7.0
#PHP_SERVER=7.1
#PHP_SERVER=7.1
Both, PHP 5.4 and PHP 7.0 are uncommented, however, when you start the Devilbox, it will use PHP 7.0 as this value overwrites any previous ones.
Change whatever version
When you have read how to change the PHP version, it should be fairly simple to change any service version. It behaves in the exact same way.
The variable names of all available services with changable versions are in the following format: <SERVICE>_SERVER
. Just look through the env_file
.
The following variables control service versions: env_php_server
, env_httpd_server
, env_mysql_server
, env_pgsql_server
, env_redis_server
, env_memcd_server
, env_mongo_server
