Overview

Available overwrites

The Devilbox ships various example configurations to overwrite the default stack. Those files are located under compose/ in the Devilbox git directory.

docker-compose.override.yml-all has all examples combined in one file for easy copy/paste. However, each example also exists in its standalone file as shown below:

host> tree -L 1 compose/

Blackfire settings

In case of Blackfire, the file is compose/docker-compose.override.yml-blackfire. This file must be copied into the root of the Devilbox git directory.

What How and where
Example compose file compose/docker-compose.override.yml-all or
compose/docker-compose.override.yml-blackfire
Container IP address 172.16.238.200
Container host name blackfire
Container name blackfire
Mount points none
Exposed port none
Available at n.a.
Further configuration BLACKFIRE_SERVER_ID and BLACKFIRE_SERVER_TOKEN must be set via .env

Blackfire env variables

Additionally the following .env variables can be created for easy configuration:

Variable Default value Description
BLACKFIRE_SERVER latest Controls the Blackfire version to use.
BLACKFIRE_SERVER_ID id A valid server id is required in order to start blackfire-agent.
BLACKFIRE_SERVER_TOKEN token A valid server token is required in order to start blackfire-agent.
BLACKFIRE_CLIENT_ID id A valid client id is required in order to use blackfire cli.
BLACKFIRE_CLIENT_TOKEN token A valid client token is required in order to use blackfire cli.

Instructions

1. Copy docker-compose.override.yml

Copy the Blackfire Docker Compose overwrite file into the root of the Devilbox git directory. (It must be at the same level as the default docker-compose.yml file).

host> cp compose/docker-compose.override.yml-blackfire docker-compose.override.yml

2. Adjust env settings

By default Blackfire is using some dummy values for BLACKFIRE_SERVER_ID and BLACKFIRE_SERVER_TOKEN. You must however aquire valid values and set the in your .env file in order for Blackfire to properly start. Those values can be obtained at their official webpage.

.env
BLACKFIRE_SERVER_ID=<valid server id>
BLACKFIRE_SERVER_TOKEN=<valid server token>

#BLACKFIRE_SERVER=1.12.0
#BLACKFIRE_SERVER=1.13.0
#BLACKFIRE_SERVER=1.14.0
#BLACKFIRE_SERVER=1.14.1
#BLACKFIRE_SERVER=1.15.0
#BLACKFIRE_SERVER=1.16.0
#BLACKFIRE_SERVER=1.17.0
#BLACKFIRE_SERVER=1.17.1
#BLACKFIRE_SERVER=1.18.0
BLACKFIRE_SERVER=latest

You must also explicitly enable the PHP blackfire module and disable xdebug via .env

.env
PHP_MODULES_ENABLE=blackfire
PHP_MODULES_DISABLE=xdebug

.env file

3. Copy blackfire php.ini template

In order for the PHP blackfire module to know where the blackfire-agent is listening, we must configure its PHP settings. There is already a default template that you can simply copy.

host> cp cfg/php-ini-7.2/devilbox-php.ini-blackfire cfg/php-ini-7.2/blackfire.ini

See also

The above example shows the procedure for PHP 7.2, if you are using a different version, you must navigate to its corresponding configuration directory.

Read more here: php.ini

4. Configure blackfire cli (optional)

If you want to use the blackfire cli from within the PHP container, its configuration must be configured. There is already a startup template which does it for you.

You first need to add the Blackfire client id and token to .env:

.env
BLACKFIRE_CLIENT_ID=<valid client id>
BLACKFIRE_CLIENT_TOKEN=<valid client token>

Then all that’s left to do is to copy the startup script which configures the blackfire cli for you.

host> cp autostart/configure-blackfire-cli.sh-example autostart/configure-blackfire-cli.sh

5. Start the Devilbox

The final step is to start the Devilbox with Blackfire.

Let’s assume you want to start php, httpd, bind and blackfire.

host> docker-compose up -d php httpd bind blackfire

TL;DR

For the lazy readers, here are all commands required to get you started. Simply copy and paste the following block into your terminal from the root of your Devilbox git directory:

# Copy compose-override.yml into place
cp compose/docker-compose.override.yml-blackfire docker-compose.override.yml

# Copy php.ini into place
cp cfg/php-ini-7.2/devilbox-php.ini-blackfire cfg/php-ini-7.2/blackfire.ini

# Set Blackfire server id and token
echo "BLACKFIRE_SERVER_ID=<valid server id>"       >> .env
echo "BLACKFIRE_SERVER_TOKEN=<valid server token>" >> .env

# Set Blackfire client id and token
echo "BLACKFIRE_CLIENT_ID=<valid client id>"       >> .env
echo "BLACKFIRE_CLIENT_TOKEN=<valid client token>" >> .env

echo "#BLACKFIRE_SERVER=1.12.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.13.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.14.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.14.1"                    >> .env
echo "#BLACKFIRE_SERVER=1.15.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.16.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.17.0"                    >> .env
echo "#BLACKFIRE_SERVER=1.17.1"                    >> .env
echo "#BLACKFIRE_SERVER=1.18.0"                    >> .env
echo "BLACKFIRE_SERVER=latest"                     >> .env

# Ensure blackfire is enabled and xdebug is disabled
# IMPORTANT: This replacement is only an example and will overwrite
#            all other enabled/disabled modules.
#            Do not do it this way.
sed -i'' 's/^PHP_MODULES_ENABLE=.*/PHP_MODULES_ENABLE=blackfire/g' .env
sed -i'' 's/^PHP_MODULES_DISABLE=.*/PHP_MODULES_ENABLE=xdebug/g' .env

# Start container
docker-compose up -d php httpd bind blackfire
