AWS::Elasticsearch::Domain EncryptionAtRestOptions - AWS CloudFormation

AWS::Elasticsearch::Domain EncryptionAtRestOptions

Whether the domain should encrypt data at rest, and if so, the AWS Key Management Service key to use.


The AWS::Elasticsearch::Domain resource is being replaced by the AWS::OpenSearchService::Domain resource. While the legacy Elasticsearch resource and options are still supported, we recommend modifying your existing Cloudformation templates to use the new OpenSearch Service resource, which supports both OpenSearch and Elasticsearch. For more information about the service rename, see New resource types in the Amazon OpenSearch Service Developer Guide.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "Enabled" : Boolean, "KmsKeyId" : String }


Enabled: Boolean KmsKeyId: String



Specify true to enable encryption at rest.

Required: No

Type: Boolean

Update requires: No interruption

Required: Conditional

Type: String

Update requires: No interruption
