The use of build and deployment tools in PHP CI/CD and automated deployment

The use of build and deployment tools in PHP CI/CD helps improve development and deployment efficiency. The following tools are mainly used: Build tools: Docker (build a consistent environment), Composer (manage dependencies) Deployment tools: Jenkins ( Powerful CI/CD server), Deployer (lightweight PHP deployment tool)

The use of build and deployment tools in PHP CI/CD and automated deployment

Continuous Integration (CI) and Continuous Deployment (CD) are key components in DevOps practices that help teams improve development and deployment efficiency. In PHP development, there are various build and deployment tools to choose from to implement the CI/CD process.

Build Tools

• Docker: Allows building and deploying applications in a consistent, portable environment. Use a Dockerfile to define your application's dependencies and configuration.
• Composer: Manage dependencies for PHP applications, including package installation and updates. It can be integrated with Docker for containerized builds.

Deployment tools

• Jenkins: Popular and powerful CI/CD server, providing a wide range of build, deployment and automation options. It supports integration with Docker, Composer and other tools.
• Deployer: A lightweight tool designed for PHP deployment. It provides out-of-the-box support for syncing files, running commands, and managing database migrations.

Practical case

Take simple PHP deployment using Docker and Deployer as an example:

Build phase:

1. Create a Dockerfile that defines the application’s dependencies and operating environment.

   FROM php:7.4-apache
   
   RUN apt-get update && apt-get install -y curl
   RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
   
   COPY . /var/www/html
   
   RUN composer install

2. Use Docker to build the image.

   docker build -t php-app .

Deployment Phase:

1. Install Deployer on the server.

2. Create a deployscript.php file to define deployment tasks.

   <?php
   
   use Deployer\Task\Context;
   
   // 服务器配置
   set('deploy_path', '/var/www/html');
   set('host', ['host.example.com']);
   
   // 任务
   task('deploy', function (Context $context) {
    upload();
    symlink('current');
    restart_php_fpm();
   });
   
   // 执行任务
   deploy()->run();

3. Deploy the application using Deployer.

By leveraging these build and deployment tools, PHP developers can implement efficient and automated CI/CD processes, significantly increasing development and deployment speed.
