Manages a KMS multi-Region replica key.
provider "aws" {
alias = "primary"
region = "us-east-1"
}
provider "aws" {
region = "us-west-2"
}
resource "aws_kms_key" "primary" {
provider = aws.primary
description = "Multi-Region primary key"
deletion_window_in_days = 30
multi_region = true
}
resource "aws_kms_replica_key" "replica" {
description = "Multi-Region replica key"
deletion_window_in_days = 7
primary_key_arn = aws_kms_key.primary.arn
}
This resource supports the following arguments:
bypass_policy_lockout_safety_check
- (Optional) A flag to indicate whether to bypass the key policy lockout safety check.
Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.
For more information, refer to the scenario in the Default Key Policy section in the _AWS Key Management Service Developer Guide_.
The default value is false
.deletion_window_in_days
- (Optional) The waiting period, specified in number of days. After the waiting period ends, AWS KMS deletes the KMS key.
If you specify a value, it must be between 7
and 30
, inclusive. If you do not specify a value, it defaults to 30
.description
- (Optional) A description of the KMS key.enabled
- (Optional) Specifies whether the replica key is enabled. Disabled KMS keys cannot be used in cryptographic operations. The default value is true
.policy
- (Optional) The key policy to attach to the KMS key. If you do not specify a key policy, AWS KMS attaches the default key policy to the KMS key.
For more information about building policy documents with Terraform, see the AWS IAM Policy Document Guide.primary_key_arn
- (Required) The ARN of the multi-Region primary key to replicate. The primary key must be in a different AWS Region of the same AWS Partition. You can create only one replica of a given primary key in each AWS Region.tags
- (Optional) A map of tags to assign to the replica key. If configured with a provider default_tags
configuration block present, tags with matching keys will overwrite those defined at the provider-level.This resource exports the following attributes in addition to the arguments above:
arn
- The Amazon Resource Name (ARN) of the replica key. The key ARNs of related multi-Region keys differ only in the Region value.key_id
- The key ID of the replica key. Related multi-Region keys have the same key ID.key_rotation_enabled
- A Boolean value that specifies whether key rotation is enabled. This is a shared property of multi-Region keys.key_spec
- The type of key material in the KMS key. This is a shared property of multi-Region keys.key_usage
- The cryptographic operations for which you can use the KMS key. This is a shared property of multi-Region keys.tags_all
- A map of tags assigned to the resource, including those inherited from the provider default_tags
configuration block.In Terraform v1.5.0 and later, use an import
block to import KMS multi-Region replica keys using the id
. For example:
import {
to = aws_kms_replica_key.example
id = "1234abcd-12ab-34cd-56ef-1234567890ab"
}
Using terraform import
, import KMS multi-Region replica keys using the id
. For example:
% terraform import aws_kms_replica_key.example 1234abcd-12ab-34cd-56ef-1234567890ab
