Docker Deployment and Installation Guide for Symfony Framework

Abstract:
Symfony framework is a powerful and popular PHP development framework that provides many convenient Features and tools to speed up the development process. Docker is a widely used containerization platform that simplifies the deployment and operation and maintenance process by packaging applications and their dependencies into containers. This article will introduce how to deploy and install the Symfony framework in a Docker environment and provide relevant code examples.

1. Install Docker

1. In Linux system, open the terminal and enter the following command to install Docker:

   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io

2. In Windows system , you can download Docker Desktop from the Docker official website https://www.docker.com/products/docker-desktop and install it according to the installation wizard.

2. Create a Symfony project

1. Use Composer to create a new Symfony project:

   composer create-project symfony/skeleton myproject

2. Enter the project Directory:

   cd myproject

3. Start the Symfony development server:

   bin/console server:start

3. Build the Docker image

1. Create a file named Dockerfile in the project root directory to define the building rules of the Docker image:

   FROM php:7.4-apache
   WORKDIR /var/www/html
   COPY . /var/www/html
   RUN apt-get update && apt-get install -y 
    libzip-dev 
    unzip 
    && docker-php-ext-install pdo_mysql zip 
    && a2enmod rewrite
   EXPOSE 80

2. Enter the following command in the terminal to build the Docker image:

   docker build -t myproject .

4. Start the Symfony project

1. Enter the following command to create a container named myproject and start the Symfony project:

   docker run -d -p 8080:80 --name myproject_container myproject

2. Now, you can visit http://localhost:8080 in your browser to view the running Symfony application.

5. Deploy using Docker Compose

1. Create a file named docker-compose.yml in the project root directory:

   version: '3'
   services:
     myproject:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 8080:80
    volumes:
      - .:/var/www/html

2. Enter the following command in the terminal to use Docker Compose to start the Symfony project:

   docker-compose up -d

6. End and Cleanup

1. Enter the following command to stop and delete the container:

   docker stop myproject_container
   docker rm myproject_container

2. If you no longer need it, you can use the following command to delete the Docker image:

   docker rmi myproject

Conclusion:
By using Docker to deploy and run the Symfony framework, we can achieve code portability, environment consistency and rapid deployment. This article provides guidelines and code examples for steps such as installing Docker, creating a Symfony project, building a Docker image, starting a Symfony project, and deploying using Docker Compose. We hope it will be helpful to you in the Docker deployment and installation process of your Symfony project.
