-- Retrieves a token that is valid for a specified registry for 12 hours. This command allows you to use the 'docker' CLI to push and pull images with Amazon ECR. If you do not specify a registry, the default registry is assumed.
--
-- The 'authorizationToken' returned for each registry specified is a base64 encoded string that can be decoded and used in a 'docker login' command to authenticate to a registry. The AWS CLI offers an 'aws ecr get-login' command that simplifies the login process.
