avm-res-oracledatabase-cloudexadatainfrastructure

This repository contains a Terraform module for deploying Oracle Database Cloud Exadata Infrastructure using Azure Verified Modules (AVM). The module provisions scalable Oracle Cloud Exadata Infrastructure in an enterprise-ready configuration on Microsoft Azure.

Known issues

  • Idempotency Issue with Exadata Infrastructure documented here
  • Update/Changes. Oracle Exadata Infrastructure resource at this moment does not support updates, so every attempt to change any of its properties will trigger the destroy and recreation of the resource. Documented here and here

Features

  • Deploys Oracle Database Cloud Exadata Infrastructure on Azure
  • Supports telemetry and monitoring
  • Configurable maintenance windows

Prerequisites

  • Terraform >= 1.9.2
  • Azure CLI
  • An Azure subscription

Requirements

The following requirements are needed by this module:

Resources

The following resources are used by this module:

Required Inputs

The following input variables are required:

Description: The number of compute nodes in the infrastructure.

Type: number

Description: The display name of the infrastructure.

Type: string

Description: Azure region where the resource should be deployed.

Type: string

Description: The name of the the Oracle Exatada Infrastructure resource.

Type: string

Description: The resource group ID where the resources will be deployed.

Type: string

Description: The number of storage servers in the infrastructure.

Type: number

Description: The Availability Zone for the resource.

Type: string

Optional Inputs

The following input variables are optional (have default values):

Description: This variable controls whether or not telemetry is enabled for the module.
For more information see https://aka.ms/avm/telemetryinfo.
If it is set to false, then no telemetry will be collected.

Type: bool

Default: true

Description: The maintenance window load time in weeks.

Type: number

Default: 0

Description: The maintenance window patching mode.

Type: string

Default: "Rolling"

Description: The maintenance window preference.

Type: string

Default: "NoPreference"

Description: A map of role assignments to create on this resource. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.

  • role_definition_id_or_name - The ID or name of the role definition to assign to the principal.
  • principal_id - The ID of the principal to assign the role to.
  • description - The description of the role assignment.
  • skip_service_principal_aad_check - If set to true, skips the Azure Active Directory check for the service principal in the tenant. Defaults to false.
  • condition - The condition which will be used to scope the role assignment.
  • condition_version - The version of the condition syntax. Valid values are '2.0'.
  • delegated_managed_identity_resource_id - (Optional) The delegated Azure Resource Id which contains a Managed Identity. Changing this forces a new resource to be created. This field is only used in cross-tenant scenario.
  • principal_type - (Optional) The type of the principal_id. Possible values are User, Group and ServicePrincipal. It is necessary to explicitly set this attribute when creating role assignments if the principal creating the assignment is constrained by ABAC rules that filters on the PrincipalType attribute.

Note: only set skip_service_principal_aad_check to true if you are assigning a role to a service principal.
