ICD Elasticsearch Module

Graduated (Supported) latest release pre-commit Renovate enabled semantic-release

Overview

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

Usage

module "icd_elasticsearch" {
  source            = "terraform-ibm-modules/icd-elasticsearch/ibm"
  version           = "X.X.X"  # Replace "X.X.X" with a release version to lock into a specific release
  resource_group_id = "xxXXxxXXxXxXXXXxxXxxxXXXXxXXXXX"
  region            = "us-south"
}

Inputs

Name Description Type Default Required
access_tags A list of access tags to apply to the Databases for Elasticsearch instance created by the module. Learn more. list(string) [] no
admin_pass The password for the database administrator. If the admin password is null, the admin user ID cannot be accessed. You can specify more users in a user block. string null no

    })
  })
 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 both provisioning is complete and the new deployment that uses that data starts. Specify a backup CRN is in the format crn:v1:<...>:backup:. If not specified, 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. Applies only if kms_encryption_enabled is true. Limitations exist for regions. For more information, see Key Protect integration or Hyper Protect Crypto Services integration. string null no
cbr_rules The list of context-based restriction rules to create. 
list(object({
    description = string
    account_id  = string

    }))) }))
    enforcement_mode = string
  }))
 [] no
elasticsearch_version The version of Databases for Elasticsearch to deploy. Possible values: 8.7, 8.10, 8.12, which requires an Enterprise Platinum pricing plan. If no value is specified, the current preferred version for IBM Cloud Databases is used. string null no
elser_model_type Trained ELSER model to be used for Elastic's Natural Language Processing. Possible values: .elser_model_1, .elser_model_2 and .elser_model_2_linux-x86_64. Learn more string ".elser_model_2_linux-x86_64" no
enable_elser_model Set it to true to install and start the Elastic's Natural Language Processing model. Learn more bool false no
existing_kms_instance_guid The GUID of a Hyper Protect Crypto Services or Key Protect instance for the CRN specified in kms_key_crn and backup_encryption_key_crn. Applies only if kms_encryption_enabled is true, skip_iam_authorization_policy is false, and you specify values for kms_key_crn or backup_encryption_key_crn. string null no
kms_encryption_enabled Whether to specify the keys used to encrypt data in the database. Specify true to identify the encryption keys. If set to false, the data is encrypted with randomly generated keys. Learn more about Key Protect integration. Learn more about HPCS integration. bool false no
kms_key_crn The root key CRN of the Key Protect or Hyper Protect Crypto Services instance to use for disk encryption. Applies only if kms_encryption_enabled is true. string null no
member_cpu_count The dedicated CPU per member that is allocated. For shared CPU, set to 0. Learn more. number 0 no
member_disk_mb The disk that is allocated per member. Learn more. number 5120 no

member_memory_mb The memory per member that is allocated. Learn more number 4096 no
members The number of members that are allocated. Learn more. number 3 no
name The name of the Databases for Elasticsearch instance. string n/a yes
plan The pricing plan for the Databases for Elasticsearch instance. Must be enterprise or platinum if the elasticsearch_version variable is set to 8.10 or later. string "enterprise" no
region The region where you want to deploy your instance. string "us-south" no
resource_group_id The resource group ID where the Databases for Elasticsearch instance is created. string n/a yes
service_credential_names The map of name and role for service credentials that you want to create for the database. map(string) {} no
service_endpoints The type of endpoint of the database instance. Possible values: public, private, public-and-private. string "public" no
skip_iam_authorization_policy Whether to create an IAM authorization policy that permits all Databases for Elasticsearch instances in the resource group to read the encryption key from the Hyper Protect Crypto Services instance specified in the existing_kms_instance_guid variable. If set to false, specify a value for the KMS instance in the existing_kms_instance_guid variable. No policy is created if kms_encryption_enabled is false. bool false no
tags The list of tags to be added to the Databases for Elasticsearch instance. list(string) [] no
use_default_backup_encryption_key Whether to use the IBM Cloud Databases generated keys. bool false no
users The list of users that have access to the database. Multiple blocks are allowed. The user password must be 10-32 characters. In most cases, you can use IAM service credentials (by specifying service_credential_names) to control access to the database instance. This block creates native database users. Learn more.
