AWS CodeCommit is a fully managed source control service that makes it easy for teams to host secure and scalable Git repositories. CodeCommit eliminates the need to operate your own source control system or worry about scaling its infrastructure. You can use CodeCommit to store anything from code to binaries, and it works seamlessly with your existing Git tools.

• Fully Managed: AWS handles the infrastructure, so you don't have to worry about server maintenance or scaling.
• Secure: CodeCommit repositories are encrypted at rest and in transit.
• High Availability: CodeCommit is designed for high availability and durability.
• Integration: Easily integrates with other AWS services and third-party tools.
• Scalable: Automatically scales to meet your needs.

1. AWS Account: Ensure you have an active AWS account.
2. IAM User: Create an IAM user with the necessary permissions to access CodeCommit.

1. Create a Repository:

   • Navigate to the AWS Management Console.
   • Go to the CodeCommit service.
   • Click on "Create repository".
   • Enter a repository name and description.
   • Click "Create".

2. Configure Git:

   • Install Git on your local machine if you haven't already.
   • Configure your Git credentials to use with CodeCommit.

3. Clone the Repository:
   • Use the HTTPS or SSH URL provided by CodeCommit to clone the repository.

Here are some basic Git commands you will use with CodeCommit:

• Clone a Repository:

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

• Add Files:

  git add <file-name>
  

• Commit Changes:

  git commit -m "Commit message"
  

• Push Changes:

  git push origin main
  

1. Clone the Repository:

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

2. Create a New Branch:

   git checkout -b new-feature
   

3. Make Changes and Commit:

   echo "print('Hello, CodeCommit!')" > hello.py
   git add hello.py
   git commit -m "Add hello.py"
   

4. Push the Branch:

   git push origin new-feature
   

5. Merge the Branch:

   • Go to the CodeCommit console.
   • Create a pull request to merge new-feature into main.
   • Review and merge the pull request.

1. Create a Repository:

   • Name: my-sample-repo
   • Description: A sample repository for learning CodeCommit

2. Clone the Repository:

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

3. Create a New File:

   echo "print('Hello, AWS CodeCommit!')" > hello.py
   

4. Add and Commit the File:

   git add hello.py
   git commit -m "Add hello.py"
   

5. Push the Changes:

   git push origin main
   

1. Create a Repository:

   • Follow the steps in the AWS Management Console to create my-sample-repo.

2. Clone the Repository:

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

3. Create a New File:

   echo "print('Hello, AWS CodeCommit!')" > hello.py
   

4. Add and Commit the File:

   git add hello.py
   git commit -m "Add hello.py"
   

5. Push the Changes:

   git push origin main
   

• Authentication Issues: Ensure your IAM user has the necessary permissions and that your Git credentials are correctly configured.
• Repository URL: Double-check the repository URL when cloning to avoid errors.
• Branch Management: Always create and work on branches for new features or bug fixes to keep the main branch stable.

In this section, you learned about AWS CodeCommit, a fully managed source control service. You set up a repository, configured Git, and practiced basic Git commands. You also completed a practical exercise to reinforce your learning. In the next module, we will explore AWS CodeBuild, a fully managed build service in AWS.
