IBM Cloud Databases for EnterpriseDB module

Important

Databases for EnterpriseDB is deprecated. As of 16 June 2025 you can't deploy new instances. Existing instances are supported until 15 October 2025. Any instances that still exist on that date will be deleted. For more information, see Deprecation of Databases for EnterpriseDB.

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

❗ 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.

❗ 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 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 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.

provider "ibm" {
  ibmcloud_api_key = "xxXXxx" # pragma: allowlist secret
  region           = "us-south"
}

admin_pass	The password for the database administrator. If the admin password is null then the admin user ID cannot be accessed. More users can be specified in a user block.	string	null	no
auto_scaling	Optional rules to allow the database to increase resources in response to usage. Only a single autoscaling block is allowed. Make sure you understand the effects of autoscaling, especially for production environments. See https://ibm.biz/autoscaling-considerations in the IBM Cloud Docs.	object({ disk = object({ capacity_enabled = optional(bool, false) free_space_less_than_percent = optional(number, 10) io_above_percent = optional(number, 90) io_enabled = optional(bool, false) io_over_period = optional(string, "15m") rate_increase_percent = optional(number, 10) rate_limit_mb_per_member = optional(number, 3670016) rate_period_seconds = optional(number, 900) rate_units = optional(string, "mb") }) memory = object({ io_above_percent = optional(number, 90) io_enabled = optional(bool, false) io_over_period = optional(string, "15m") rate_increase_percent = optional(number, 10) rate_limit_mb_per_member = optional(number, 114688) rate_period_seconds = optional(number, 900) rate_units = optional(string, "mb") }) })	null	no
backup_crn	The CRN of a backup resource to restore from. The backup is created by a database deployment with the same service ID. The backup is loaded after provisioning and the new deployment starts up that uses that data. A backup CRN is in the format crn:v1:<…>:backup:. If omitted, the database is provisioned empty.	string	null	no
backup_encryption_key_crn	The CRN of a Key Protect or Hyper Protect Crypto Services encryption key that you want to use for encrypting the disk that holds deployment backups. Applies only if use_ibm_owned_encryption_key is false and use_same_kms_key_for_backups is false. If no value is passed, and use_same_kms_key_for_backups is true, the value of kms_key_crn is used. Alternatively set use_default_backup_encryption_key to true to use the IBM Cloud Databases default encryption. Bare in mind that backups encryption is only available in certain regions. See Bring your own key for backups and Using the HPCS Key for Backup encryption.	string	null	no
cbr_rules	(Optional, list) List of CBR rules to create	list(object({ description = string account_id = string rule_contexts = list(object({ attributes = optional(list(object({ name = string value = string }))) })) enforcement_mode = string }))	[]	no

edb_version	Version of the Enterprise DB instance to provision. If no value is passed, the current preferred version of IBM Cloud Databases is used. For our version policy, see https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-versioning-policy for more details	string	null	no
kms_key_crn	The CRN of a Key Protect or Hyper Protect Crypto Services encryption key to encrypt your data. Applies only if use_ibm_owned_encryption_key is false. By default this key is used for both deployment data and backups, but this behaviour can be altered using the use_same_kms_key_for_backups and backup_encryption_key_crn inputs. Bare in mind that backups encryption is only available in certain regions. See Bring your own key for backups and Using the HPCS Key for Backup encryption.	string	null	no
member_cpu_count	Allocated dedicated CPU per member. Minimum number of CPU allowed is 3. Learn more	number	3	no

region	The region where you want to deploy your instance.	string	"us-south"	no
remote_leader_crn	A CRN of the leader database to make the replica(read-only) deployment. The leader database is created by a database deployment with the same service ID. A read-only replica is set up to replicate all of your data from the leader deployment to the replica deployment by using asynchronous replication. For more information, see https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=databases-for-enterprisedb-read-only-replicas	string	null	no
resource_group_id	The resource group ID where Enterprise DB instance will be created.	string	n/a	yes
resource_tags	Optional list of tags to be added to the Enterprise DB instance.	list(string)	[]	no
service_credential_names	Map of name, role for service credentials that you want to create for the database	map(string)	{}	no
service_endpoints	Specify whether you want to enable the public, private, or both service endpoints. Supported values are 'public', 'private', or 'public-and-private'.	string	"private"	no
skip_iam_authorization_policy	Set to true to skip the creation of IAM authorization policies that permits all Databases for EnterpriseDB instances in the given resource group 'Reader' access to the Key Protect or Hyper Protect Crypto Services key that was provided in the kms_key_crn and backup_encryption_key_crn inputs. This policy is required in order to enable KMS encryption, so only skip creation if there is one already present in your account. No policy is created if use_ibm_owned_encryption_key is true.	bool	false	no
use_default_backup_encryption_key	When use_ibm_owned_encryption_key is set to false, backups will be encrypted with either the key specified in kms_key_crn, or in backup_encryption_key_crn if a value is passed. If you do not want to use your own key for backups encryption, you can set this to true to use the IBM Cloud Databases default encryption for backups. Alternatively set use_ibm_owned_encryption_key to true to use the default encryption for both backups and deployment data.	bool	false	no
use_ibm_owned_encryption_key	IBM Cloud Databases will secure your deployment's data at rest automatically with an encryption key that IBM hold. Alternatively, you may select your own Key Management System instance and encryption key (Key Protect or Hyper Protect Crypto Services) by setting this to false. If setting to false, a value must be passed for the kms_key_crn input.	bool	true	no
use_same_kms_key_for_backups	Set this to false if you wan't to use a different key that you own to encrypt backups. When set to false, a value is required for the backup_encryption_key_crn input. Alternatiely set use_default_backup_encryption_key to true to use the IBM Cloud Databases default encryption. Applies only if use_ibm_owned_encryption_key is false. Bare in mind that backups encryption is only available in certain regions. See Bring your own key for backups and Using the HPCS Key for Backup encryption.	bool	true	no
users	A list of users that you want to create on the database. Multiple blocks are allowed. The user password must be in the range of 10-32 characters. Be warned that in most case using IAM service credentials (via the var.service_credential_names) is sufficient to control access to the Enterprise Db instance. This blocks creates native enterprise database users, more info on that can be found here https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=databases-for-enterprisedb-user-management&interface=api	list(object({ name = string password = string # pragma: allowlist secret type = optional(string) role = optional(string) }))	[]	no
