This module implements an instance of the IBM Cloud Databases for EnterpriseDB service.

:exclamation: The module does not support major version upgrades or updates to encryption and backup encryption keys. To upgrade the version, create another instance of Databases for EnterpriseDBs with the updated version.

:exclamation: The module only supports setting the disk encryption and backup encryption key CRNs on creation and no update support is available. The KMS manual or automatic key rotation may be used to change the key value and initiate the re-encryption of the deployment.

### Usage

IBM Cloud Databases supports:

- Key Protect encryption in `us-south`, `us-east`, and `eu-de` for backup encryption. For more information, see [Bring Your Own Key for Backups](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-key-protect&interface=ui#key-byok) in the IBM Cloud Docs.

- Hyper Protect Crypto Services in all regions for backup encryption. For more information, see [Hyper Protect Crypto Services for Backup encryption](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hpcs#use-hpcs-backups) in the IBM Cloud Docs.

If you enable key management encryption and no value is passed for 'backup_encryption_key_crn', the value of 'kms_key_crn' is used.

```hcl

provider "ibm" {

  ibmcloud_api_key = "xxXXxx" # pragma: allowlist secret

  region           = "us-south"

}

module "enterprise_db" {

  # Replace "main" with a GIT release version to lock into a specific release

  source            = "git::https://github.com/terraform-ibm-modules/terraform-ibm-icd-edb?ref=main"

  resource_group_id = "xxXXxxXXxXxXXXXxxXxxxXXXXxXXXXX"

  name              = "my-instance"

  region            = "us-south"

}

```
