This project includes setting up a CI/CD pipeline using AWS CodePipeline to automate the deployment of a web application. It demonstrates my skills in setting up a robust CI/CD pipeline, infrastructure as code, and application monitoring. The pipeline includes the following stages:

  • Source: Connect the project’s source code repository (e.g., GitHub or AWS CodeCommit).
  • Build: Use AWS CodeBuild to build and package your application.
  • Test: Deploy your application to an Amazon EC2 instance, run tests, and ensure it’s working correctly.
  • Deploy: Automatically deploy the application to Amazon EC2 and/or AWS Fargate.
  • Monitoring: Integrate Amazon CloudWatch for monitoring and create alarms for key metrics.

Project Steps

Step 1: AWS Account Setup

  • If you don’t already have an AWS account, sign up for one.
  • Configure your AWS account security settings and enable MFA for added security.

Step 2: Create or Prepare Your Web Application

  • Have the web application’s source code ready in a version control repository (e.g., GitHub, AWS CodeCommit).
  • Ensure that your application can be built and deployed programmatically.

Step 3: Create an EC2 Instance for Deployment

  • Launch an Amazon EC2 instance where your application will be deployed.
  • Choose an appropriate Amazon Machine Image (AMI) with a Linux distribution of your choice (e.g., Amazon Linux, Ubuntu).
  • Set up necessary security groups, key pairs, and IAM roles for the EC2 instance.

Step 4: Set Up AWS CodePipeline

  • Go to the AWS CodePipeline service in the AWS Management Console.
  • Create a new pipeline with the following stages:
    • Source: Connect to your source code repository (e.g., GitHub, AWS CodeCommit).
    • Build: Configure an AWS CodeBuild project to build and package your application.
    • Test: Deploy your application to the EC2 instance, run tests, and validate its functionality.
    • Deploy: Automatically deploy the application to the EC2 instance.

Step 5: Configure AWS CodeBuild

  • Create a CodeBuild project that defines the build environment, build commands, and artifacts.
  • Specify build specifications and dependencies in the buildspec.yaml file in your application repository.
  • Ensure CodeBuild can access your source code repository.

Step 6: Configure Deployment Scripts

  • Create deployment scripts or automation tools (e.g., bash scripts, Ansible playbooks) that can deploy your application to the EC2 instance.
  • These scripts should handle application deployment, server configuration, and environment setup.

Step 7: Set Up Monitoring and Alarming

  • Integrate Amazon CloudWatch to monitor key metrics (e.g., server CPU usage, application logs).
  • Create CloudWatch Alarms to trigger notifications or scaling actions based on specific conditions.

Step 8: Security and IAM Setup

  • Implement IAM roles with the necessary permissions for CodePipeline, CodeBuild, and your EC2 instances.
  • Implement security best practices like key rotation, IAM instance profiles, and security group rules.

Step 9: Testing and Validation

  • Test the entire pipeline by making changes to your source code repository.
  • Verify that the changes are automatically built, tested, and deployed without issues.

Step 10: Documentation and Cost Monitoring

  • Document the entire setup, including pipeline configuration, scripts, and IAM roles.
  • Set up AWS Budgets or billing alerts to monitor and control costs.

Step 11: Cleanup and Deactivation

  • When done, make sure to deactivate and delete AWS resources to avoid unnecessary charges.
