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.
