# Symfony Docker A [Docker](https://www.docker.com/)-based installer and runtime for the [Symfony](https://symfony.com) web framework, with full [HTTP/2](https://symfony.com/doc/current/weblink.html) and HTTPS support. ![CI](https://github.com/dunglas/symfony-docker/workflows/CI/badge.svg) ## Getting Started 1. Run `docker-compose up` (the logs will be displayed in the current shell) 2. Open `https://localhost` in your favorite web browser and [accept the auto-generated TLS certificate](https://stackoverflow.com/a/15076602/1352334) 3. **Enjoy!** ## Features * Production, development and CI ready * Automatic HTTPS (in dev and in prod!) * HTTP/2, HTTP/3 and [Server Push](https://symfony.com/doc/current/web_link.html) support * [Vulcain](https://vulcain.rocks)-enabled * Just 2 services (PHP FPM and Caddy server) * Super-readable configuration ## Selecting a Specific Symfony Version Use the `SYMFONY_VERSION` environment variable to select a specific Symfony version. For instance, use the following command to install Symfony 4.4: $ SYMFONY_VERSION=4.4.* docker-compose up --build To install a non-stable version of Symfony, use the `STABILITY` environment variable during the build. The value must be [a valid Composer stability option](https://getcomposer.org/doc/04-schema.md#minimum-stability)) . For instance, use the following command to use the `master` branch of Symfony: $ STABILITY=dev docker-compose up --build ## Customize Server Name Use the `SERVER_NAME` environment variable to define your custom server name. $ SERVER_NAME=symfony.wip docker-compose up --build ## Debugging The default Docker stack is shipped without a Xdebug stage. It's easy though to add [Xdebug](https://xdebug.org/) to your project, for development purposes such as debugging tests or API requests remotely. ### Add a Development Stage to the Dockerfile To avoid deploying Symfony Docker to production with an active Xdebug extension, it's recommended to add a custom stage to the end of the `Dockerfile`. ```Dockerfile # Dockerfile FROM symfony_php as symfony_php_dev ARG XDEBUG_VERSION=2.9.8 RUN set -eux; \ apk add --no-cache --virtual .build-deps $PHPIZE_DEPS; \ pecl install xdebug-$XDEBUG_VERSION; \ docker-php-ext-enable xdebug; \ apk del .build-deps ``` ### Configure Xdebug with Docker Compose Override Using an [override](https://docs.docker.com/compose/reference/overview/#specifying-multiple-compose-files) file named `docker-compose.debug.yaml` ensures that the production configuration remains untouched. As example, an override could look like this: ```yaml # docker-compose.debug.yaml version: "3.4" services: php: build: context: . target: symfony_php_dev environment: # See https://docs.docker.com/docker-for-mac/networking/#i-want-to-connect-from-a-container-to-a-service-on-the-host # See https://github.com/docker/for-linux/issues/264 # The `remote_host` below may optionally be replaced with `remote_connect_back` XDEBUG_CONFIG: >- remote_enable=1 remote_host=host.docker.internal remote_port=9001 idekey=PHPSTORM # This should correspond to the server declared in PHPStorm `Preferences | Languages & Frameworks | PHP | Servers` # Then PHPStorm will use the corresponding path mappings PHP_IDE_CONFIG: serverName=symfony ``` Then run: $ docker-compose -f docker-compose.yml -f docker-compose.debug.yml up -d ### Troubleshooting Inspect the installation with the following command. The requested Xdebug version should be displayed in the output. $ docker-compose exec php php --version PHP ... with Xdebug v2.8.0 ... ### Editing Permissions on Linux If you work on linux and cannot edit some of the project files right after the first installation, you can run `docker-compose run --rm php chown -R $(id -u):$(id -g) .` to set yourself as owner of the project files that were created by the docker container. ### Fix Chrome/Brave SSL If you have a SSL trust issues, download the self-signed certificate and run : $ sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /path/to/you/certificate.cer ## Credits Created by [Kévin Dunglas](https://dunglas.fr), co-maintained by [Maxime Helias](https://twitter.com/maxhelias) and sponsored by [Les-Tilleuls.coop](https://les-tilleuls.coop).
