Automating Drupal Site Deployments with CI/CD

With the constant evolution of Drupal, particularly with recent versions like Drupal 10 and Drupal 11, automating deployments has become essential to leverage new features and maintain an agile and reliable development cycle. This article will guide you through the coding approaches and techniques to automate the deployment of Drupal sites using CI/CD.

I. Understanding CI/CD for Drupal

Continuous Integration (CI) and Continuous Deployment (CD) are practices that allow for the development, testing, and deployment of applications in a more efficient and reliable manner. CI involves developers regularly merging their code changes into a central repository, where they are automatically tested. CD extends this process by automatically deploying the code to production after passing the tests. This ensures that the software can be released at any time with minimal manual intervention.

II. Setting Up a CI/CD Pipeline for Drupal

To set up a CI/CD pipeline for Drupal, it is crucial to choose the right tools and services. Below is an example of a GitLab CI configuration for Drupal 10, which uses PHP 8.1 and Symfony 6.2—versions that bring significant improvements in performance and security.

# Example GitLab CI configuration for a Drupal 10 project
image: drupal:10
stages:
 - build
 - test
 - deploy
build_job:
 stage: build
 script:
   - composer install --no-interaction
test_job:
 stage: test
 script:
   - ./vendor/bin/phpunit
deploy_job:
 stage: deploy
 script:
   - echo "Deploying to the production server"
   - rsync -avz ./* production-server:/path/to/drupal

This configuration defines three stages: build, test, and deploy. The project is built with Composer, tested with PHPUnit, and deployed using rsync. This approach ensures that the code is always ready for deployment, with automated tests to ensure quality.

III. Technical Approaches and Tools

1. CI/CD Tools

• GitLab CI: A powerful tool to automate CI/CD tasks, particularly well-suited for Drupal projects.
• GitHub Actions: Ideal for projects hosted on GitHub, allowing automation of workflows directly from the platform.
• Jenkins: A widely-used open-source tool that offers modern pipelines for continuous delivery.

IV. Automated Testing

Automated testing is crucial to ensure code quality before deployment. Use frameworks like PHPUnit for unit testing or Behat for behavior-driven development. Integrating these tests into your CI/CD pipeline allows you to catch issues early in the development cycle.

V. Deployment Strategies

• Automated Deployment: Configure your pipeline to automatically deploy code after tests have been validated.
• Database Updates: Use Drupal’s update hooks to manage database schema changes during deployments.
• Configuration Synchronization: Ensure configuration synchronization across environments to avoid inconsistencies.
