Setting up AWS CodeCommit for Git

AWS CodeCommit is AWS’s own Git offering. It operates primarily on IAM users, so an important part of setting up CodeCommit is to first create IAM user(s).

• Login to AWS Console as the root user.
• Create a new repo at CodeCommit.
• Create and commit a simple new file, say, README.md.
• Create an IAM user with two important credentials:
  • AWSCodeCommitPowerUser policy.
  • Enable console access.
  • (Remember to download the generated IAM credentials as CSV)
• Logout of AWS Console.

Now that the IAM user has been created, the following steps are to be completed by the IAM user instead of the root user.

• Login as the new IAM user.
• Browse to IAM->Users->(the new IAM user)->Security Credentials->SSH keys for AWS CodeCommit->Generate.
  • (It is usual to see red permission warnings along the way, no worries)
  • Remember to download the generated CodeCommit credentials as CSV.
• Still as the IAM user, browse to CodeCommit and locate the correct repo.
• Copy the HTTPS clone URL.
• On your local Git client (e.g., GitHub client, VS Code), clone the repo using the copied clone URL.
  • When prompted for username and password, use the set of CodeCommit credentials that was download as CSV. Do not confuse that with the earlier set of IAM credentials.
  • If using git command line, git clone https://git-codecommit.us-east-2.amazonaws.com/v1/repos/MyDemoRepo my-demo-repo
• And that’s it!
