symfony

Quick start

The following files can be used to set up a local docker environment suitable for Symfony with a database container. The only changes that need to be applied would be to remove ARG DEVELOPMENT_MODE=true from the Dockerfile and set appropriate production environment variables.

Place all files in the root directory. Then run docker-compose up -d and visit http://localhost:81

# Dockerfile

FROM quay.io/continuouspipe/symfony-php7.1-apache:latest
ARG GITHUB_TOKEN=
ARG DEVELOPMENT_MODE=true

COPY . /app/
RUN container build

# docker-compose.yml

About

This is a series of images that let you run a Symfony application under different PHP and web server environments (NGINX or Apache).

How to use

Environment variables

The following variables are supported

Variable	Description	Expected values	Default
SYMFONY_DOCTRINE_MODE	Whether to use Doctrine migrations, schema update or nothing. Automatically detected based on installed composer packages by default	auto/migrations/schema/off	auto
SYMFONY_DOCTRINE_WAIT_TIMEOUT	The maximum time to wait for the database to become available during the database build	time in seconds	10
SYMFONY_ENV	The Symfony env to use, when the app reads this variable	string	prod
SYMFONY_FLEX	Whether the project uses the symfony/flex component and folder structure	true/false	autodetected based on whether in composer.lock
SYMFONY_MAJOR_VERSION	The major version of Symfony that will be used	2, 3	auto-detected based on location of console script
SYMFONY_CONSOLE	The location of the Symfony console script	file path	auto-detected
SYMFONY_WEB_APP_ENV_REWRITE	Whether to use web/app_*.php when SYMFONY_ENV != prod	true, false	false
APP_ENDPOINT	The uri of the web application php endpoint	domain relative uri	auto-detected based on SYMFONY_ENV and SYMFONY_WEB_APP_ENV_REWRITE
APP_ENDPOINT_REWRITE	Determines whether to redirect urls that don't match webroot files to the APP_ENDPOINT	true/false	true
APP_ENDPOINT_REGEX	A regex used to define allowed application endpoints, see site_phpfpm.conf.tmpl	string	auto-detected
APP_ENDPOINT_STRICT	Restricts allowed application endpoints to only that of the APP_ENDPOINT environment variable	true/false	true

The following variables have had their defaults changed from the php-nginx image so that Symfony runs better:

Variable	Description	Expected values	Default
PHP_MEMORY_LIMIT	The memory limit for PHP.	string	256M
PHP_OPCACHE_MAX_ACCELERATED_FILES	How many files PHP can cache into Opcache	integer	20000
PHP_REALPATH_CACHE_SIZE	How many resolved file locations PHP can cache into the realpath cache.	string	4096K
PHP_REALPATH_CACHE_TTL	How many seconds can PHP cache the resolved file locations in it's realpath cache	integer	600

Custom build and startup scripts

To run commands during the build and startup sequences that the base images add, please add usr/local/share/container/plan.sh for a project, or usr/local/share/container/baseimage-{number}.sh if creating another base image.

This allows you to define and override bash functions that the base images add.

In addition to the bash functions defined in this base image's parent images:

• the base image functions
• either the php-nginx image functions
• or the php-apache image functions

This base image adds the following bash functions:

function	description	executed on
do_symfony_build	Updates the permissions of the Symfony app as required for composer and web write access	do_composer
do_symfony_config_create	Creates an empty parameters.yml that the composer installation can update via the incenteev/parameters-handler package	do_symfony_build
do_symfony_directory_create	Creates directories that may not be present in the codebase but are required before composer can run to install dependencies	do_symfony_build
do_symfony_build_permissions	Fix the owner and permissions of the web-writable directories, to allow symfony to function	do_composer
do_cache_clear	Clears/warms up the Symfony cache	nothing by default
do_database_build	Installs or updates the database schema depending on whether the database exists	nothing by default
do_database_install	Runs database install process (assumes Doctrine ORM/migrations), which is by default do_database_schema_create, do_database_migrations_mark_done, do_database_fixtures	do_database_build
do_database_update	Runs database update process(assumes Doctrine ORM/migrations), which is by default do_database_migrate	do_database_build
do_database_schema_create	Runs doctrine:schema:create	do_database_install
do_database_schema_update	Runs doctrine:schema:update --force (not recommmended)	nothing by default
do_database_migrations_mark_done	Marks all Doctrine migrations as done	do_database_install
do_database_migrate	Runs doctrine:migrations:migrate --no-interaction	do_database_update

These functions can be triggered via the /usr/local/bin/container command, dropping off the "do_" part. e.g:

/usr/local/bin/container build # runs do_build /usr/local/bin/container start_supervisord # runs do_start_supervisord
