AWS CodeCommit Multiple Account Config
This doc shows how to set up Git repos and SSH to allow the use of CodeCommit with more than one AWS account. This applies to macOS/Linux/Unix.

Initial Setup
Follow the SSH setup steps from the CodeCommit Docs, but be sure to configure ~/.ssh/config as shown in this Gist.

If your config file is already configured as in the docs, feel free to update it, but you'll have to change the remote settings of any repos you've already cloned (see "Updating an Existing Repo" below).

Cloning a Repo
When newly cloning a repo, make the following change to your clone command:

_ _
Command git clone ssh://git-codecommit.us-east-1.amazonaws.com/v1/repos/my-repo
Becomes git clone ssh://awscc-account1/v1/repos/my-repo
where awscc-account1 should be the name chosen on the Host line of the corresponding account in ~/.ssh/config.

Updating an Existing Repo
When working with a repo that is already cloned to your local machine, make the same change in: /path/to/my-repo/.git/config

In the [remote "origin"] section, update the url as shown above in "Cloning a Repo".
