Project Name: CI/CD GitHub Actions and Terraform Infrastructure as Code for AWS Cloud

Client Name: Beams Renovation

Project Duration: 1 month

Team Size: 1 DevOps engineer

Scenario

A development team is building a web application that needs to be deployed on AWS. The infrastructure includes:

  • An Amazon S3 bucket for static file hosting.
  • An Amazon RDS instance for the database.
  • An Amazon ECS cluster for containerized application deployment.
  • An Amazon CloudFront distribution for content delivery.

The team wants to automate the deployment process to ensure consistency, reliability, and efficiency. They decide to use Terraform for infrastructure as code (IaC) and GitHub Actions for the CI/CD pipeline.

Objectives

  1. Infrastructure Provisioning: Use Terraform to define and provision AWS infrastructure.
  2. Continuous Integration: Automatically run tests and build Docker images when code is pushed to the repository.
  3. Continuous Deployment: Deploy the updated application and infrastructure changes to AWS automatically.

Steps to Implement

1. Set Up Terraform for AWS Infrastructure

  • Define Infrastructure: Create Terraform configuration files to define the required AWS resources.

2. Create GitHub Actions Workflow

  • Define CI/CD Workflow: Create a GitHub Actions workflow file to automate the build, test, and deployment processes.

Explanation

Terraform Configuration

  • Defines the AWS resources needed for the web application.
  • Manages the lifecycle of these resources (creation, update, and deletion).

GitHub Actions Workflow

Build Job:

  • Checks out the code from the repository.
  • Builds a Docker image for the application.
  • Pushes the Docker image to Amazon ECR.

Deploy Job:

  • Checks out the code from the repository.
  • Configures AWS credentials using secrets stored in GitHub.
  • Initializes Terraform and applies the configuration to provision/update AWS infrastructure.

Benefits

  • Automation: Automates the entire process of building, testing, and deploying the application and infrastructure changes.
  • Consistency: Ensures that the infrastructure is consistently configured across different environments.
  • Scalability: Allows easy scaling of infrastructure by updating Terraform configuration files and reapplying them.
  • Version Control: Keeps infrastructure changes under version control, allowing tracking and rollback of changes.
