AWS CodePipeline | AWS CodeDeploy | AWS CodeBuild | CodeCommit | Deploy WebApp a Hands on Lab

Introduction

In this tutorial, we will guide you through deploying a web application on AWS using several key services: AWS CodePipeline, CodeCommit, CodeBuild, and CodeDeploy. This practical lab is particularly useful for those preparing for the AWS Certified Developer (DVA-C01) certification exam. By the end of this guide, you will have a solid understanding of how to integrate these AWS services to automate your deployment workflow.

Step 1: Set Up AWS CodeCommit

• Create a CodeCommit Repository

  • Log in to your AWS Management Console.
  • Navigate to CodeCommit and click on "Create Repository."
  • Enter a name for your repository and click "Create."

• Clone the Repository

  • Use the following command to clone your repository locally:

    git clone https://git-codecommit.<region>.amazonaws.com/v1/repos/<repository-name>
    

• Add Your Web Application Code

  • Copy your web application files into the cloned repository folder.
  • Use the following commands to commit your changes:

    git add .
    git commit -m "Initial commit"
    git push
    

Step 2: Configure AWS CodeBuild

• Create a Build Project

  • Navigate to AWS CodeBuild in the console.
  • Click on "Create build project."
  • Enter a project name and select the source provider as CodeCommit.

• Specify Build Environment

  • Choose the operating system, runtime, and build specification.
  • You can define your build commands in a file named buildspec.yml. Here’s an example:

    version: 0.2
    phases:
      install:
        runtime-versions:
          nodejs: 14
      build:
        commands:
          - npm install
          - npm run build
    artifacts:
      files:
        - '**/*'
    

• Configure Build Triggers

  • Set up triggers to start a build automatically when changes are pushed to the repository.

Step 3: Set Up AWS CodeDeploy

• Create a CodeDeploy Application

  • Go to AWS CodeDeploy and click "Create application."
  • Choose a name and deployment type, typically “In-place” or “Blue/Green.”

• Create a Deployment Group

  • Define the deployment group and specify the target instances using tags or an Auto Scaling group.

• Configure the AppSpec File

  • Create an appspec.yml file in your project root to specify how CodeDeploy should manage your deployment:

    version: 0.0
    os: linux
    files:
      - source: /
        destination: /var/www/myapp
    hooks:
      AfterInstall:
        - location: scripts/start_server.sh
          timeout: 300
          runas: root
    

Step 4: Create a CodePipeline

• Set Up a Pipeline

  • Navigate to AWS CodePipeline and click "Create pipeline."
  • Provide a name for your pipeline and select the default role.

• Add Source Stage

  • Choose CodeCommit as the source provider and select your repository.

• Add Build Stage

  • Select CodeBuild as the build provider and choose the build project you created earlier.

• Add Deploy Stage

  • Choose CodeDeploy as the deploy provider and select the application and deployment group.

• Review and Create

  • Review all configurations and click "Create pipeline."

Conclusion

You have now set up a complete CI/CD pipeline using AWS CodePipeline, CodeCommit, CodeBuild, and CodeDeploy to automate the deployment of your web application. This integration allows for efficient development and deployment processes, which are critical for modern web applications.

Next steps include testing your pipeline by making changes to your application and observing the automated deployment process. Additionally, consider exploring advanced features like monitoring deployments and integrating with other AWS services for enhanced functionality.
