IBM Cloud Messages for RabbitMQ module

This module implements an instance of the IBM Cloud Messages for RabbitMQ 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 IBM Cloud Messages for RabbitMQ with the updated version and follow the steps in Upgrading to a new Major Version in the IBM Cloud Docs.

Usage

IBM Cloud Messages for RabbitMQ 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 Docs.

Inputs

Name	Description	Type	Default	Required
access_tags	A list of access tags to apply to the rabbitmq 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/messages-for-rabbitmq?topic=messages-for-rabbitmq-autoscaling 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 key, that you want to use for encrypting disk that holds deployment backups. Only used if var.kms_encryption_enabled is set to true. If no value is passed here, the value passed for the 'kms_key_crn' variable is used, unless 'use_default_backup_encryption_key' is set to 'true'. BYOK for backups is available only in US regions us-south and us-east, and eu-de. Only keys in the us-south and eu-de are durable to region failures. To ensure that your backups are available even if a region failure occurs, you must use a key from us-south or eu-de. Take note that Hyper Protect Crypto Services for IBM Cloud® Databases backups is not currently supported, so if no value is passed here, but a HPCS value is passed for var.kms_key_crn, databases backup encryption will use the default encryption keys.	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
cpu_count	Allocated dedicated CPU per member. For shared CPU, set to 0. For more information, see https://cloud.ibm.com/docs/messages-for-rabbitmq?topic=messages-for-rabbitmq-resources-scaling	number	0	no
disk_mb	Allocated disk per member. For more information, see https://cloud.ibm.com/docs/messages-for-rabbitmq?topic=messages-for-rabbitmq-resources-scaling	number	1024	no
endpoints	Endpoints available to the database instance (public, private, public-and-private)	string	"private"	no
existing_kms_instance_guid	The GUID of the Hyper Protect or Key Protect instance in which the key specified in var.kms_key_crn and var.backup_encryption_key_crn is coming from. Only required if var.kms_encryption_enabled is 'true', var.skip_iam_authorization_policy is 'false', and passing a value for var.kms_key_crn and/or var.backup_encryption_key_crn.	string	null	no
instance_name	The name to give the RabbitMQ 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 Service (HPCS) that you want to use for disk encryption. Only used if var.kms_encryption_enabled is set to true.	string	null	no
members	Allocated number of members. For more information, see: https://cloud.ibm.com/docs/messages-for-rabbitmq?topic=messages-for-rabbitmq-resources-scaling	number	3	no
memory_mb	Allocated memory per-member. For more information, see: https://cloud.ibm.com/docs/messages-for-rabbitmq?topic=messages-for-rabbitmq-resources-scaling	number	1024	no
plan	The name of the service plan that you choose for your RabbitMQ instance	string	"standard"	no
rabbitmq_version	The version of RabbitMQ to deploy. If no value passed, the current ICD preferred version is used.	string	null	no
region	The region where you want to deploy your instance.	string	"us-south"	no
resource_group_id	The resource group ID where the RabbitMQ instance will be created.	string	n/a	yes
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 RabbitMQ instances in the given resource group to read the encryption key from the Hyper Protect or Key Protect instance passed in var.existing_kms_instance_guid. If set to 'false', a value must be passed for var.existing_kms_instance_guid. 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 RabbitMQ instance.	list(any)	[]	no
use_default_backup_encryption_key	Set to true to use default ICD randomly generated keys.	bool	false	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 RabbitMQ instance. This blocks creates native RabbitMQ database users, more info on that can be found here https://cloud.ibm.com/docs/messages-for-rabbitmq?topic=messages-for-rabbitmq-user-management	list(object({ name = string password = string # pragma: allowlist secret type = string # "type" is required to generate the connection string for the outputs. role = optional(string) }))	[]	no
