As you probably know, I am a big Symfony<\/a> fan\u00a0\ud83d\ude42 In the last few years I used Vagrant<\/a> to set up my Symfony development environment more or less as described here<\/a>. But we now have Docker<\/a> and it\u2019s time to move forward with a new setup. Docker containers are generally more lightweight than Vagrant virtual machines, so starting and stopping them is extremely fast. They also take a lot less disk space.<\/p>\n

To setup a Docker container you need a Dockerfile<\/code> file and to combine several containers we use the docker-compose.yml<\/code> file. For our environment we will need two containers, one with the latest Ubuntu LTS to host the web server and our project files and one for MySQL.<\/p>\n

The first container is defined in the Dockerfile<\/code> file as below:<\/p>\n

FROM ubuntu:16.04\r\nADD . \/app\r\nRUN apt-get update\r\nRUN apt-get install -y php apache2 libapache2-mod-php7.0 php-mysql php-intl git git-core curl php-curl php-xml composer zip unzip php-zip\r\n# Configure Apache\r\nRUN rm -rf \/var\/www\/* \\\r\n    && a2enmod rewrite \\\r\n    && echo \"ServerName localhost\" >> \/etc\/apache2\/apache2.conf\r\nADD vhost.conf \/etc\/apache2\/sites-available\/000-default.conf\r\n# Install Symfony\r\nRUN mkdir -p \/usr\/local\/bin\r\nRUN curl -LsS https:\/\/symfony.com\/installer -o \/usr\/local\/bin\/symfony\r\nRUN chmod a+x \/usr\/local\/bin\/symfony\r\n# Add main start script for when image launches\r\nADD run.sh \/run.sh\r\nRUN chmod 0755 \/run.sh\r\nWORKDIR \/app\r\nEXPOSE 80\r\nCMD [\"\/run.sh\"]<\/pre>\n
Add this file in a new folder. We also need the vhost.conf<\/code> and run.sh<\/code> files used in the code from above.<\/p>\n
The vhost.conf<\/code> file is used to configure the apache virtual host:<\/p>\n
<VirtualHost *:80>\r\n    ServerName localhost\r\n    DocumentRoot \/app\/my_project\/web\r\n    <Directory \/app\/my_project\/web>\r\n        Options -Indexes\r\n        AllowOverride All\r\n        Require all granted\r\n    <\/Directory>\r\n<\/VirtualHost><\/pre>\n
The run.sh<\/code> file runs when the container starts and just makes sure that the cache<\/code> and logs<\/code> folders are set up before launching the apache web server:<\/p>\n
#!\/bin\/bash\r\nmkdir -p my_project\/app\/cache my_project\/app\/logs\r\ntouch my_project\/app\/logs\/prod.log\r\ntouch my_project\/app\/logs\/dev.log\r\nchgrp -R www-data .\r\nchmod -R g+w my_project\/app\/cache my_project\/app\/logs\r\nsource \/etc\/apache2\/envvars\r\ntail -F \/var\/log\/apache2\/* my_project\/app\/logs\/prod.log my_project\/app\/logs\/dev.log &\r\nexec apache2 -D FOREGROUND<\/pre>\n
That\u2019s all for our main Ubuntu container, we now need to create the docker-compose.yml<\/code> file:<\/p>\n
version: \"2\"\r\nservices:\r\n    mysql:\r\n        image: mysql:5.7\r\n        container_name: mysqldb\r\n        ports:\r\n            - \"4000:3306\"\r\n        expose:\r\n            - \"3306\"\r\n        environment:\r\n            MYSQL_ROOT_PASSWORD: yourrootpassword\r\n    site:\r\n        build: .\r\n        container_name: myproject\r\n        ports:\r\n            - \"8080:80\"\r\n        expose:\r\n            - \"80\"\r\n        depends_on:\r\n            - mysql\r\n        volumes:\r\n          - .:\/app<\/pre>\n
This will tell Docker to first start an MySQL 5.7 container, then our Ubuntu container that will be able to access the MySQL container using the mysql<\/code> host name.<\/p>\n
Start everything with the docker-compose up<\/code> command.<\/p>\n
When it\u2019s done, open a new terminal (let the latest docker compose command run, do not stop it) and use the docker ps<\/code> command to see the running containers:<\/p>\n
\"\"<\/p>\n
Now, you can take the id<\/code> of the Ubuntu container and ssh into it:<\/p>\n
docker exec -t -i [ID] bash<\/pre>\n
Here you will start a new Symfony project as always (you will have to delete the my_project<\/code> folder created by Docker first):<\/p>\n
rm -rf my_project\r\nsymfony new my_project 2.8<\/pre>\n
If you name you project something else (yes, you will probably do that) just replace the all my_folder<\/code> occurrences in the files and commands above with the actual name of your project.<\/p>\n
After you created the new Symfony project, it is better to rebuild the Docker containers so the setup of the cache<\/code> and logs<\/code> folders will be as intended. In the terminal window where you launched Docker, press Ctrl+C<\/code> to stop it then run docker-compose up<\/code> again.<\/p>\n
That\u2019s it! You can now access your new Symfony project using the following URL: http:\/\/localhost:8080\/. To connect to MySQL you will use the mysql host name:<\/p>\n
parameters:\r\n    database_host: mysql\r\n    database_port: null\r\n    database_name: symfony\r\n    database_user: root\r\n    database_password: yourrootpassword<\/pre>\n
 <\/p>\n
Thank you! Please let me know in the comments if you have any suggestions to improve this setup or problems running it.<\/p>\n","protected":false},"excerpt":{"rendered":"
