Unleashing the Power of CI/CD: How Our PHP Development Team Streamlines Software Delivery

Hello, fellow tech enthusiasts! Today, we’re excited to share our insights into the world of Continuous Integration (CI), Continuous Deployment (CD), and DevOps, and how our PHP development team at Fuse Web harnesses these practices to deliver high-quality software more efficiently. As a crucial component of the DevOps culture, CI/CD bridges the gap between development and operations teams, enabling them to work in unison, streamline processes, and ultimately achieve a more cohesive and effective software delivery lifecycle.

Why CI/CD Matters

In today’s fast-paced digital world, businesses require software solutions that are not only top-notch in quality but can also be delivered quickly and iteratively. This is where CI/CD comes into play. By embracing CI/CD, our team at Fuse Web ensures a smooth development process, faster release cycles, and improved collaboration among team members.

CI/CD in a Nutshell

Continuous Integration (CI) involves regularly merging code changes into a central repository. This helps in early detection of integration issues and reduces the time spent on fixing bugs. Continuous Deployment (CD), on the other hand, is the automated deployment of code changes to production, ensuring that new features and updates reach end-users swiftly.

Our Approach to CI/CD at Fuse Web

1. Version Control and Code Review

We use Git as our version control system, allowing our team to effectively collaborate on projects. This enables us to maintain a clean and organised codebase, and conduct thorough code reviews to ensure that only high-quality code gets merged.

Example: To ensure a streamlined code review process, we follow the Git Feature Branch Workflow. Developers create a new branch for each feature or bugfix, and submit a pull request (PR) when the work is completed. The PR is then reviewed by at least one other team member before being merged into the main branch.

# Creating a new feature branch
git checkout -b my-feature-branch

# Pushing changes to the remote repository
git push origin my-feature-branch

2. Automated Testing

Our team incorporates unit, integration, and end-to-end testing in our development process. These tests are run automatically during the CI stage, allowing us to catch and resolve issues before they make their way into production. Additionally, we continuously strive to improve our test coverage to ensure the reliability of our applications.

Example: We use PHPUnit for unit testing in our PHP projects. The following is a simple test case for a basic calculator class:

use Codeception\Test\Unit;
use App\Calculator;

class CalculatorTest extends Unit
{
    public function testAddition()
    {
        $calculator = new Calculator();
        $result = $calculator->add(2, 3);
        $this->assertEquals(5, $result);
    }
}

3. Continuous Deployment

By integrating our CI pipeline with deployment tools like AWS CodeDeploy and Docker, we automate the deployment process. This ensures that new features and updates reach our clients as quickly as possible, without sacrificing quality. We also have rollback mechanisms in place, so if any issues arise during deployment, we can revert to the previous stable version with minimal disruption.

Example: To automate deployments, we use GitHub Actions along with AWS CodeDeploy. Our GitHub Actions workflow is triggered by a Git push event, and it builds a Docker image of the application, pushes it to a container registry, and then deploys it to an AWS ECS cluster.

# .github/workflows/ci_cd.yml
name: CI/CD

on:
  push:
    branches:
      - main

jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Login to Docker Registry
      run: echo ${{ secrets.DOCKER_HUB_TOKEN }} | docker login -u ${{ secrets.DOCKER_HUB_USERNAME }} --password-stdin

    - name: Build and push Docker image
      run: |
        docker build -t myapp:${{ github.sha }} .
        docker tag myapp:${{ github.sha }} myregistry/myapp:${{ github.sha }}
        docker push myregistry/myapp:${{ github.sha }}

    - name: Deploy to AWS ECS
      uses: aws-actions/amazon-ecs-deploy-task-definition@v1
      with:
        task-definition: path/to/task-definition.json
        service: myapp-service
        cluster: myapp-cluster
        container-name: myapp-container
        image: myregistry/myapp:${{ github.sha }}
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        region: us-west-2

4. Monitoring and Logging:

We employ robust monitoring and logging solutions, such as AWS CloudWatch and ELK Stack, to track the health and performance of our applications. This enables us to respond quickly to potential issues and make data-driven decisions to improve our software.

Example: To monitor our PHP applications, we integrate with AWS CloudWatch by installing the AWS CloudWatch Agent on our instances and configuring it to collect logs and custom PHP application metrics.

// cloudwatch-agent-config.json
{
  "agent": {
    "metrics_collection_interval": 60
  },
  "metrics": {
    "append_dimensions": {
      "InstanceId": "${aws:InstanceId}"
    },
    "metrics_collected": {
      "php_app": {
        "measurement": [
          "requests",
          "response_time"
        ],
        "metrics_collection_interval": 60,
        "resources": [
          "/var/log/php_app/metrics.log"
        ]
      }
    }
  },
  "logs": {
    "logs_collected": {
      "files": {
        "collect_list": [
          {
            "file_path": "/var/log/php_app/error.log",
            "log_group_name": "php_app",
            "log_stream_name": "{instance_id}/error.log"
          },
          {
            "file_path": "/var/log/php_app/access.log",
            "log_group_name": "php_app",
            "log_stream_name": "{instance_id}/access.log"
          }
        ]
      }
    }
  }
}
