One of the cool things about CodeCommit is the support for IAM authentication. And if you are running this workshop from a Cloud9 workspace, you can leverage the fact that your terminal is already pre-authenticated with valid AWS credentials.
Run the following commands from your terminal:
git config --global credential.helper '!aws codecommit credential-helper $@' git config --global credential.UseHttpPath true
Now configure the git client with username and email, so your commits have an author defined.
git config --global user.name "Replace with your name" git config --global user.email "email@example.com"
