Amazon SageMaker now supports adding authentication to requests for pulling images stored in your private Docker Registry to build containers for real-time inference. Amazon SageMaker makes it easy to deploy your trained models to production with a single click, so you can start generating real-time inferences with low latency. You can bring your own code for performing real-time inference using container images stored in Amazon Elastic Container Registry (Amazon ECR) or a private Docker registry of your choice. SageMaker can now authenticate with your private Docker registry so you can have an additional layer of security and the peace of mind that requests to your container images are serviced only for authorized entities.
