Day 50: Your CI/CD Pipeline on AWS - Part 1 🚀☁

Welcome to Day 50 of your DevOps journey! Over the next 4 days, you'll set up a CI/CD pipeline on AWS using powerful tools like CodeCommit, CodeBuild, CodeDeploy, CodePipeline, and S3. Let's break it down step by step, starting with CodeCommit.

---

What is CodeCommit?

AWS CodeCommit is a fully-managed source control service that enables you to:

• Securely store, manage, and version your source code.

• Collaborate with your team using branching and merging workflows.

• Easily integrate with other AWS services for CI/CD pipelines.

• Get compliance and audit logs for tracking code changes.

With CodeCommit, you can manage your repositories efficiently and use them as the foundation for your CI/CD pipelines.

Tasks for Today

Task 01: Set Up a Code Repository on CodeCommit and Clone It Locally

Requirements:

• AWS account with IAM user permissions for CodeCommit and GitCredentials.

• Git installed locally.

Steps:

1. Create a Repository on CodeCommit:

   • Open the AWS Management Console.

   • Go to CodeCommit > Create Repository.

   • Provide a name for your repository (e.g., my-cicd-repo) and optional description.

   • Click Create Repository.

2. Set Up Git Credentials in AWS IAM:

   • Open IAM in the AWS Console.

   • Go to your user profile and select Security credentials.

   • Under HTTPS Git credentials for AWS CodeCommit, click Generate credentials.

   • Save the credentials (username and password) securely.

3. Clone the Repository Locally:

   • Open a terminal and use the following command:

       git clone https://git-codecommit.<region>.amazonaws.com/v1/repos/my-cicd-repo
     

     Replace <region> with your AWS region (e.g., us-east-1).

   • When prompted, use the Git credentials from step 2.

Task 02: Add a New File Locally and Push Changes to CodeCommit

Steps:

1. Navigate to the Cloned Repository:

    cd my-cicd-repo
   

2. Add a New File Locally:

   • Create a file (e.g., hello-world.txt) using a text editor or terminal:

       echo "Hello, CodeCommit!" > hello-world.txt
     

3. Stage the File for Commit:

    git add hello-world.txt
   

4. Commit the Changes:

    git commit -m "Added hello-world.txt"
   

5. Push the Changes to CodeCommit:

    git push origin main
   

   • Ensure the branch name is correct (main or master, depending on your setup).

Key Takeaways

• CodeCommit acts as the foundation for your CI/CD pipeline by securely hosting your code.

• Setting up Git credentials is essential for integrating your local environment with AWS.

• With a simple git add, commit, and push, you can sync your local changes to CodeCommit.
