  enabled = true
resource "aws_ebs_default_kms_key" "default" {
  key_arn = aws_kms_key.key.arn

resource "aws_ebs_encryption_by_default" "default" {
  enabled = true
resource "aws_ebs_default_kms_key" "ebs_default_kms_key" {
  count = length(var.ebs_default_kms_key)
  key_arn = element(var.kms_key_id, lookup(var.ebs_default_kms_key[count.index], "kms_key_id"))
resource "aws_ebs_default_kms_key" "this" {
  key_arn = var.key_arn

resource "aws_ebs_default_kms_key" "this" {
  count    = var.ebs_default_kms_key_arn == "" ? 0 : 1

Explanation in Terraform Registry

Provides a resource to manage the default customer master key (CMK) that your AWS account uses to encrypt EBS volumes. Your AWS account has an AWS-managed default CMK that is used for encrypting an EBS volume when no CMK is specified in the API call that creates the volume. By using the aws_ebs_default_kms_key resource, you can specify a customer-managed CMK to use in place of the AWS-managed default CMK.

NOTE: Creating an aws_ebs_default_kms_key resource does not enable default EBS encryption. Use the aws_ebs_encryption_by_default to enable default EBS encryption. NOTE: Destroying this resource will reset the default CMK to the account's AWS-managed default CMK for EBS.
