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 AES256
encryption type is used, Amazon ECR uses server-side encryption with Amazon S3-managed encryption
keys which encrypts your data at rest using an AES256 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 AWS Key Management Service key stored in AWS Key Management Service (AWS KMS) to encrypt your images. For more information, see Amazon ECR encryption at rest in the Amazon Elastic Container Registry User Guide.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
JSON
{
"EncryptionType" : String,
"KmsKey" : String
}
YAML
EncryptionType: String
KmsKey: String
Properties
EncryptionType-
The encryption type to use.
If you use the
KMSencryption type, the contents of the repository will be encrypted using server-side encryption with AWS Key Management Service key stored in AWS KMS. When you use AWS KMS to encrypt your data, you can either use the default AWS managed AWS KMS key for Amazon ECR, or specify your own AWS KMS key, which you already created.If you use the
KMS_DSSEencryption type, the contents of the repository will be encrypted with two layers of encryption using server-side encryption with the AWS KMS Management Service key stored in AWS KMS. Similar to theKMSencryption type, you can either use the default AWS managed AWS KMS key for Amazon ECR, or specify your own AWS KMS key, which you've already created.If you use the
AES256encryption 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.For more information, see Amazon ECR encryption at rest in the Amazon Elastic Container Registry User Guide.
