We are excited to announce the developer preview of our new API documentation for AWS SDK for JavaScript v3. Please follow instructions on the landing page to leave us your feedback.
The encryption type to use.
If you use the KMS encryption type, the contents of the repository will
be encrypted using server-side encryption with Key Management Service key stored in KMS. When you
use KMS to encrypt your data, you can either use the default Amazon Web Services managed KMS key
for Amazon ECR, or specify your own KMS key, which you already created. For more
information, see Protecting data using server-side
encryption with an KMS key stored in Key Management Service (SSE-KMS) in the
Amazon Simple Storage Service Console Developer Guide.
If you use the AES256 encryption type, Amazon ECR uses server-side encryption
with Amazon S3-managed encryption keys which encrypts the images in the repository using an
AES-256 encryption algorithm. For more information, see Protecting data using
server-side encryption with Amazon S3-managed encryption keys (SSE-S3) in the
Amazon Simple Storage Service Console Developer Guide.
Optional kmsIf you use the KMS encryption type, specify the KMS key to use for
encryption. The alias, key ID, or full ARN of the KMS key can be specified. The key
must exist in the same Region as the repository. If no key is specified, the default
Amazon Web Services managed KMS key for Amazon ECR will be used.
The encryption configuration for the repository. This determines how the contents of your repository are encrypted at rest.
By default, when no encryption configuration is set or the
AES256encryption type is used, Amazon ECR uses server-side encryption with Amazon S3-managed encryption keys which encrypts your data at rest using an AES-256 encryption algorithm. This does not require any action on your part.For more control over the encryption of the contents of your repository, you can use server-side encryption with Key Management Service key stored in Key Management Service (KMS) to encrypt your images. For more information, see Amazon ECR encryption at rest in the Amazon Elastic Container Registry User Guide.
