This module implements an instance of IBM Cloud Databases for Redis.
❗ 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 Redis with the updated version and follow the steps in Upgrading to a new Major Version doc in the IBM Cloud Docs.
IBM Cloud Databases supports only Key Protect encryption for backups, not Hyper Protect Crypto Services. If you enable key management encryption and no value is passed for 'backup_encryption_key_crn', the value of 'kms_key_crn' is used. And if a HPCS value is set for kms_key_crn
, the database backup encryption uses the default encryption keys. For more information, see Hyper Protect Crypto Services Integration in the IBM Cloud Documents.

Name | Description | Type | Default | Required |
---|---|---|---|---|
access_tags | A list of access tags to apply to the Redis instance created by the module, see https://cloud.ibm.com/docs/account?topic=account-access-tags-tutorial for more details | list(string) |
[] |
no |
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://cloud.ibm.com/docs/databases-for-redis?topic=databases-for-redis-autoscaling in the IBM Cloud Docs. | object({ |
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 KMS (Key Protect or Hyper Protect Crypto Services) key to use for encrypting the disk that holds deployment backups. Only used if var.kms_encryption_enabled is set to true. There are limitation per region on the type of KMS service (Key Protect or Hyper Protect Crypto Services) and region for those services. See https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-key-protect&interface=ui#key-byok and https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hpcs#use-hpcs-backups | string |
null |
no |
cbr_rules | (Optional, list) List of CBR rules to create | list(object({ |
[] |
no |
configuration | Database Configuration. Default values will get picked up if not all the values are passed. | object({ |
null |
no |
cpu_count | Allocated dedicated CPU per member. For shared CPU, set to 0. Learn more | number |
0 |
no |
disk_mb | Allocated disk per member. Learn more | number |
1024 |
no |
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 |
existing_kms_instance_guid | The GUID of the Hyper Protect Crypto Services or Key Protect instance in which the key specified in var.kms_key_crn and var.backup_encryption_key_crn is coming from. Required only if var.kms_encryption_enabled is set to true, var.skip_iam_authorization_policy is set to false, and you pass a value for var.kms_key_crn, var.backup_encryption_key_crn, or both. | string |
null |
no |
instance_name | The name to give the Redis instance. | string |
n/a | yes |
kms_encryption_enabled | Set this to true to control the encryption keys used to encrypt the data that you store in IBM Cloud® Databases. If set to false, the data is encrypted by using randomly generated keys. For more info on Key Protect integration, see https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-key-protect. For more info on HPCS integration, see https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hpcs | bool |
false |
no |
kms_key_crn | The root key CRN of a Key Management Services like Key Protect or Hyper Protect Crypto Services (HPCS) that you want to use for disk encryption. Only used if var.kms_encryption_enabled is set to true. | string |

service_credential_names | Map of name, role for service credentials that you want to create for the database | map(string) |
{} |
no |
skip_iam_authorization_policy | Set to true to skip the creation of an IAM authorization policy that permits all Redis database instances in the resource group to read the encryption key from the KMS instance. If set to false, pass in a value for the KMS instance in the existing_kms_instance_guid variable. In addition, no policy is created if var.kms_encryption_enabled is set to false. | bool |
false |
no |
tags | Optional list of tags to be added to the Redis instance. | list(any) |
[] |
no |
use_default_backup_encryption_key | Set to true to use default ICD randomly generated keys. | bool |

no |
users | A list of users that you want to create on the database. Users block is supported by Redis version >= 6.0. 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 Redis instance. This blocks creates native redis database users, more info on that can be found here https://cloud.ibm.com/docs/databases-for-redis?topic=databases-for-redis-user-management&interface=ui | list(object({ |
