This pattern shows how to grant Amazon SageMaker notebook instances and users temporary access to an AWS CodeCommit repository that’s in another AWS account. This pattern also shows how you can grant granular permissions for specific actions each entity can perform on each repository.
Organizations often store CodeCommit repositories in a different AWS account than the account that hosts their development environment. This multi-account setup helps control access to the repositories and reduces the risk of their accidental deletion. To grant these cross-account permissions, it’s a best practice to use AWS Identity and Access Management (IAM) roles. Then, predefined IAM identities in each AWS account can temporarily assume the roles to create a controlled chain of trust across the accounts.
Note: You can apply a similar procedure to grant other IAM identities cross-account access to a CodeCommit repository. For more information, see Configure cross-account access to an AWS CodeCommit repository using roles in the AWS CodeCommit User Guide.v
