encryptionType

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.

If you use the KMS_DSSE encryption type, the contents of the repository will be encrypted with two layers of encryption using server-side encryption with the KMS Management Service key stored in KMS. Similar to the KMS encryption type, you can either use the default Amazon Web Services managed KMS key for Amazon ECR, or specify your own KMS key, which you've already created.

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 AES256 encryption algorithm.
