Quickly deploy and install the Symfony framework using Docker

Use Docker to quickly deploy and install the Symfony framework

Introduction:
Symfony is a popular PHP framework that provides a complete set of tools and components. Help developers build efficient and scalable web applications. Deploying and installing the Symfony framework is an important task during development. This article will introduce how to use Docker to quickly deploy and install the Symfony framework, and provide specific code examples.

Steps:

1. Install Docker
   Before we begin, we need to install Docker. Choose the appropriate installation method based on your operating system, and make sure Docker's environment variables are set correctly.
2. Create Dockerfile
   Create a file named Dockerfile in the root directory of the project and add the following content:

# 使用基础镜像
FROM php:7.4-apache

# 设置工作目录
WORKDIR /var/www/html

# 安装依赖
RUN apt-get update && apt-get install -y 
        git 
        zip 
        unzip 
    && rm -rf /var/lib/apt/lists/* 
    && curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# 安装 Symfony CLI
RUN wget https://get.symfony.com/cli/installer -O - | bash

3. Build the Docker image
   In the terminal , enter the project root directory, and execute the following command to build the Docker image:

docker build -t symfony-app .

4. Run the Docker container
   Execute the following command to run the Docker container, and map port 80 in the container to the host 8080 port of the host:

docker run -p 8080:80 -d symfony-app

5. Install the Symfony framework
   In the terminal, run the following command to enter the Docker container:

docker exec -it <container_id> bash

Among them, <container_id></container_id> is the container ID obtained by executing the docker ps command.

After entering the container, execute the following command to install the Symfony framework:

symfony new my_project_name --full

Where, my_project_name is the name you want to give the project.

6. Visit the Symfony application
   Visit http://localhost:8080/my_project_name/public in your browser, you will be able to see the welcome page of the Symfony application.

Conclusion:
This article introduces the steps to quickly deploy and install the Symfony framework using Docker, and provides specific code examples. By using Docker, we can quickly build a development environment, maintain the consistency of the environment, and improve development efficiency. I hope this article can help you successfully deploy and install the Symfony framework and carry out development work smoothly.
