Over the past few months I’ve been using CodeCommit on projects that live in different AWS accounts but always using CodeCommit in the Singapore region. This means I need to connect through the same endpoint (git-codecommit.ap-southeast-1.amazonaws.com) but need to be able to specify different access keys depending on which account I am working with.
