How to install the Symfony framework with Docker
Introduction:
Symfony is a popular PHP framework that enables developers to Ability to quickly build scalable web applications. When using the Symfony framework to develop projects, Docker containerization technology can provide a clean and consistent development environment to help us develop and deploy more efficiently. This article will introduce how to install and configure the Symfony framework using Docker, with specific code examples.
Step 1: Install Docker and Docker Compose
Before we begin, we need to install Docker and Docker Compose. The official Docker website provides detailed installation tutorials, and you can choose the appropriate installation method according to your operating system.
Step 2: Create Symfony project
After installing Docker and Docker Compose, we can start creating the Symfony project. First, create a new directory to store Symfony project-related files, then enter the directory in the terminal and execute the following command:
docker run --rm --interactive --tty --volume $PWD:/app composer:latest create-project symfony/skeleton my_project_name
In the above command, $PWD
represents the current directory, my_project_name
is your project name.
After successful execution, the basic structure of the Symfony application will be created in the my_project_name
folder in the current directory.
Step 3: Configure the Docker Compose file
Next, we need to configure the Docker Compose file to create a development environment containing Apache and PHP containers. In the root directory of the Symfony project, create a file called docker-compose.yml
and add the following content in it:
version: '3' services: php: image: php:7.4-apache volumes: - './my_project_name:/var/www/html' ports: - '80:80' depends_on: - db db: image: mysql:5.7 environment: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: my_project_name MYSQL_USER: my_project_name_user MYSQL_PASSWORD: my_project_name_password
In the above configuration file, we used PHP 7.4 and Apache mirror as our development environment, and MySQL 5.7 is configured as our database service. Through the volumes
command, mount the Symfony project directory to the /var/www/html
path of the container, so that we can access the project code inside the container.
Step 4: Start the Docker container
After configuring the docker-compose.yml
file, we can start the Docker container through the following command:
docker-compose up -d
This command All containers required by Symfony applications will be started and run in the background.
Step 5: Check Symfony Framework Installation
After all containers are up and running normally, we can visit Symfony’s welcome page through the browser to ensure that the Symfony framework is successfully installed. Enter http://localhost
in the browser address bar. If you can see the Symfony welcome page, the installation is successful.
If you encounter any problems during the installation process, you can view the log information of the container through the following command:
docker-compose logs
Summary:
Installing the Symfony framework through Docker containerization technology can simplify the deployment of the project and maintenance, while providing a unified development environment. Through the steps and code examples provided in this article, you can quickly set up a Symfony development environment and start developing using the Symfony framework. Hope this article helps you!
