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). .. code-block:: bash host> cp compose/docker-compose.override.yml-blackfire docker-compose.override.yml .. seealso:: * :ref:`docker_compose_override_yml` * :ref:`add_your_own_docker_image` * :ref:`overwrite_existing_docker_image` 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. .. code-block:: bash :caption: .env BLACKFIRE_SERVER_ID= BLACKFIRE_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`` .. code-block:: bash :caption: .env PHP_MODULES_ENABLE=blackfire PHP_MODULES_DISABLE=xdebug .. seealso:: :ref:`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. .. code-block:: bash host> cp cfg/php-ini-7.2/devilbox-php.ini-blackfire cfg/php-ini-7.2/blackfire.ini .. seealso:: 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: :ref:`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``: .. code-block:: bash :caption: .env BLACKFIRE_CLIENT_ID= BLACKFIRE_CLIENT_TOKEN= Then all that's left to do is to copy the startup script which configures the blackfire cli for you. .. code-block:: bash host> cp autostart/configure-blackfire-cli.sh-example autostart/configure-blackfire-cli.sh .. seealso:: * :ref:`custom_scripts_globally` 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``. .. code-block:: bash host> docker-compose up -d php httpd bind blackfire .. seealso:: :ref:`start_the_devilbox` 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: .. code-block:: bash # 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=" >> .env echo "BLACKFIRE_SERVER_TOKEN=" >> .env # Set Blackfire client id and token echo "BLACKFIRE_CLIENT_ID=" >> .env echo "BLACKFIRE_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
