You can now run different PHP versions per project: Release v3.0.0-beta-0.1

Custom scripts per PHP version

You can provide custom startup commands via bash scripts to each of the PHP container individually. This may be useful to specify additional software to install or additional settings to apply during the initial startup.

Per PHP version scripts are always executed before global scripts.

Table of Contents


You can add custom shell scripts for each PHP version separately.


Provided scripts must end by the file extension .sh and should be executable. Anything not ending by .sh will be ignored.


Provided scripts will be executed by the root user within the PHP container.


Startup scripts can be added to cfg/php-startup-X.Y/. See the directory structure for PHP startup script directories inside ./cfg/ directory:

host> ls -l path/to/devilbox/cfg/ | grep 'php-startup'

drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-5.2/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-5.3/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-5.4/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-5.5/
drwxr-xr-x  2 cytopia cytopia 4096 Apr  3 22:04 php-startup-5.6/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-7.0/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-7.1/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-7.2/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-7.3/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-7.4/
drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-startup-8.0/

Custom scripts are added by placing a file into cfg/php-startup-X.X/ (where X.X stands for your PHP version). The file must end by .sh in order to be executed by the PHP container.

Some of the PHP startup directories contain a few example files with the file suffix -example. If you want to use them, copy these files to a new name without the -example suffix and ensure they end by .sh.


The scripts will be executed by the PHP container during initial startup. Whenever you change your scripts, ensure to restart the Devilbox.


The scripts will always be executed inside the PHP container (Debian Linux) and will be run with root privileges. It is however possible to drop privileges within the script to have them executed as a normal user.


Installing Microsoft ODBC driver

This example will add Microsofts ODBC driver to PHP 7.1. These drivers are required in order to make the PHP modules pdo_sqlsrv and sqlsrv work. The two mentioned modules are already available in the PHP container, but are explicitly disabled via PHP_MODULES_DISABLE.

They won’t work without the ODBC driver installed, which unfortunately cannot be bundled, as it requires every user to accept a license/EULA by Microsoft.

# Navigate to starup dir of PHP 7.1
host> cd path/to/devilbox/cfg/php-startup-7.1

# Create an .sh file
host> touch

# Open the file in your favourite editor
host> vi

Paste the following into and ensure to accept the EULA by changing ACCEPT_EULA=N to ACCEPT_EULA=Y.

# This script will automatically install the Microsoft ODBC driver for MsSQL
# support for PHP during startup.
# In order for it to work, you must read and accept their License/EULA:

# ------------------------------------------------------------------------------------------------
# EDIT THE VARIABLE BELOW TO ACCEPT THE EULA (If you agree to their terms)
# ------------------------------------------------------------------------------------------------

### Set this to "Y" (capital 'Y') if you accept the EULA.

# ------------------------------------------------------------------------------------------------
# ------------------------------------------------------------------------------------------------

### Where to retrieve the deb package

### Pre-flight check
if [ "${ACCEPT_EULA}" != "Y" ]; then
     echo "MS ODBC EULA not accepted. Aborting installation."
     exit 0

### EULA accepted, so we can proceed

# Extract latest *.deb packate
MSODBC_DEB="$( curl -k -sS "${MSODBC_URL}" | grep -Eo 'msodbcsql[-._0-9]+?_amd64\.deb' | tail -1 )"

# Download to temporary location
curl -k -sS "${MSODBC_URL}${MSODBC_DEB}" > "/tmp/${MSODBC_DEB}"

# Install

# Remove artifacts
rm -f "/tmp/${MSODBC_DEB}"


The script will not work, if you have not accepted the EULA.

Running commands as devilbox user

As mentioned above, all scripts are run by the root user. If you do need something to be executed as the normal user: devilbox, you can simply su inside the shell script.

The following example will install grunt and start a NodeJS application as the devilbox user for the PHP 7.1 Docker container only.

# Install grunt as devilbox user
su -c "npm install grunt" -l devilbox

# Start a NodeJS application with pm2 as devilbox user
su -c "cd /shared/httpd/my-node/src/; pm2 start index.js" -l devilbox
