aws_kms_alias

Provides an alias for a KMS customer master key. AWS Console enforces 1-to-1 mapping between aliases & keys, but API (hence Terraform too) allows you to create as many aliases as the account limits allow you.

Example Usage

resource "aws_kms_key" "a" {}

resource "aws_kms_alias" "a" {
  name          = "alias/my-key-alias"
  target_key_id = "${aws_kms_key.a.key_id}"
}

Argument Reference

The following arguments are supported:

• name - (Optional) The display name of the alias. The name must start with the word "alias" followed by a forward slash (alias/)
• name_prefix - (Optional) Creates an unique alias beginning with the specified prefix. The name must start with the word "alias" followed by a forward slash (alias/). Conflicts with name.
• target_key_id - (Required) Identifier for the key for which the alias is for, can be either an ARN or key_id.

Attributes Reference

In addition to the arguments, the following attributes are exported:

• arn - The Amazon Resource Name (ARN) of the key alias.
• target_key_arn - The Amazon Resource Name (ARN) of the target key identifier.
