PHP development: continuous integration and continuous deployment using GitLab CI/CD

With the development of the Internet and the increasing number of application scenarios, more and more companies and developers are beginning to use PHP language to develop websites and applications. In the development process, continuous integration and continuous deployment have become a trend, which can greatly improve development efficiency and product quality. GitLab CI/CD has received widespread attention and use as a tool to achieve continuous integration and continuous deployment.

GitLab is an open source tool for managing and deploying software code. It can implement functions such as code version control, project management, code quality analysis, continuous integration and continuous deployment. GitLab CI/CD is GitLab's continuous integration and continuous deployment feature that can be used to build, test, and deploy applications. Below, we will introduce how to use GitLab CI/CD to implement continuous integration and continuous deployment of PHP development.

1. Create a GitLab project and set up CI/CD

First, create a GitLab project. Here we take the Laravel framework as an example. In the project, we need to add a .gitlab-ci.yml file. This file is used to configure GitLab CI/CD, including defining processes, stages, variables, etc.

In the .gitlab-ci.yml file, we need to define some variables, such as database, environment variables, etc., for subsequent use in continuous integration and continuous deployment.

2. Testing and building

The next step is to test and build the code. This stage usually requires writing some scripts to automate testing and build operations. In the Laravel framework, we can use tools such as PHPUnit and Laravel Mix to accomplish these operations. In the .gitlab-ci.yml file, define scripts to perform the corresponding operations.

3. Image packaging and push

After testing and building are completed, we need to package the application into a Docker image and push it to the GitLab private warehouse or Docker Hub Waiting in the mirror warehouse. This step requires setting up the Dockerfile file and CI/CD process to implement.

4. Deployment

The last step is to deploy our application. Application deployment can be completed using tools such as Kubernetes, Docker Compose, and Ansible.

At this stage, we need to set server access credentials, specify the container orchestration method, etc. In addition, we also need to configure GitLab Runner to start the deployment operation so that the deployment log can be viewed in GitLab.

Summary

By using GitLab CI/CD, we can realize automated testing, building and deployment of PHP applications. This greatly reduces manual operations during the deployment process and reduces the occurrence of errors, while also improving the efficiency of the entire development team.
