Navigating AWS CodeCommit with Temporary Credentials

When working with AWS CodeCommit, you might encounter challenges while attempting to clone repositories when using temporary credentials. As a crucial piece in version control, resolving these issues is essential for seamless development workflows. In this guide, we will discuss an error that many users face when trying to access AWS CodeCommit using Git and temporary IAM credentials.

The Problem: Access Denied

You’ve already set up your AWS CLI with the relevant configuration, including profiles for both your IAM user and the Admin role. The process has been successful for AWS CLI operations like listing S3 buckets, but when you attempt to clone a CodeCommit repository, you receive a 403 Forbidden error. Specifically, the command fails with a message indicating that access to the repository is denied.

Understanding Your Configuration

Your current AWS CLI profile setup includes:

A default profile for general AWS operations.

A parthiva profile with your IAM user credentials.

An admin profile that uses an ARN to assume the Admin role, requiring MFA.

This configuration should, in theory, give you the necessary permissions, but it doesn’t seem to automatically apply to CodeCommit when you use Git.

Solutions to Access AWS CodeCommit

1. Using the Default Region

Since your default region is set to eu-central-1, you can simplify your clone command. Here’s how to do it:

This command allows you to access the repository without needing to specify the region, as it defaults to your configured region.

2. Specifying a Different AWS Region

If you intend to clone a repository located in a different AWS region, make sure to specify its region explicitly:

This is crucial for avoiding region-related access issues.

3. Using the Admin Profile

If you want to ensure that the admin profile is being used, you can adjust your clone command accordingly:

This format ensures that the command leverages the configurations and permissions set in your Admin profile.

Troubleshooting Tips

If you continue to encounter issues:

Check IAM Permissions: Ensure that the role AdminAccess has the correct permissions assigned to allow CodeCommit access.

MFA Authentication: If your session requires an MFA token and you're prompted every time you try to use Git, ensure your authentication session is valid. Use AWS CLI commands that require the Admin role to refresh your credentials.

Profile Validation: Verify that your profiles are correctly configured and that you're applying the correct profile in each command.

Conclusion

By following the steps outlined above, you should be able to successfully clone your AWS CodeCommit repositories while using temporary credentials and manage your projects more effectively. Utilizing Git with AWS can initially seem challenging, but with the right configuration, you can streamline your development processes efficiently.
