Docker practice: Install Symfony and configure the environment

Introduction:

Docker is an open source containerization platform that can help us quickly build an environment , deploy applications and manage containers. In this article, we will introduce how to use Docker to install Symfony and configure the corresponding environment.

Part One: Installing Docker

Before you begin, make sure you have Docker installed. If it is not installed, please refer to Docker official documentation to complete the installation.

Part 2: Create a Symfony project

1. Open a terminal and enter the following command to create a Symfony project:

$ docker run -it --rm -v $PWD:/app composer create-project symfony/skeleton my-symfony-project

This command will use Composer to Create a Symfony project and place it in the my-symfony-project folder.

2. Enter the project directory:

$ cd my-symfony-project

Part 3: Create Dockerfile

1. Create a file named in the project root directory Dockerfile file and add the following content to the file:

FROM php:7.4-cli

# 安装Symfony所需的扩展
RUN docker-php-ext-install pdo_mysql

# 安装Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# 设置工作目录
WORKDIR /app

# 复制项目文件到容器中
COPY . .

# 安装项目依赖
RUN composer install --no-dev --optimize-autoloader

# 暴露容器的80端口
EXPOSE 80

# 执行Symfony的Web服务器命令
CMD php -S 0.0.0.0:80 -t public/

This Dockerfile file defines the steps for creating a Symfony container. It uses the php:7.4-cli image as the base image and installs the extensions and Composer required by Symfony. Then, copy the project files into the container, install the project dependencies, and expose the port in the container.

Part 4: Build the Docker image

1. Execute the following command in the terminal to build the Docker image:

$ docker build -t my-symfony-app .

This command will build a Docker image based on the Dockerfile Image named my-symfony-app.

Part 5: Run the Symfony application

1. Execute the following command in the terminal to start the Symfony application:

$ docker run -it --rm -p 8080:80 my-symfony-app

This command will start the container , and map the container's port 80 to the host's port 8080.

Part 6: Verify the Symfony application

1. Visit http://localhost:8080 in the browser to view the Symfony application. If everything is fine, you will see Symfony's welcome page.

Conclusion:

By using Docker, we can quickly set up a Symfony development environment and easily deploy applications. This article introduces how to install Symfony and configure the corresponding environment. I hope it will be helpful to you. If you haven't tried using Docker to manage your applications, I highly recommend you start giving it a try and enjoy the convenience of containerization.
