Usage

This module is optimized to work with the Claranet terraform-wrapper tool which set some terraform variables in the environment needed by this module. More details about variables set by the terraform-wrapper available in the documentation.

⚠️ Since modules version v8.0.0, we do not maintain/check anymore the compatibility with Hashicorp Terraform. Instead, we recommend to use OpenTofu.

logs_destinations_ids	List of destination resources IDs for logs diagnostic destination. Can be Storage Account, Log Analytics Workspace and Event Hub. No more than one of each can be set. If you want to specify an Azure EventHub to send logs and metrics to, you need to provide a formated string with both the EventHub Namespace authorization send ID and the EventHub name (name of the queue to use in the Namespace) separated by the `	` character.	list(string)	n/a

namespace_parameters	Object to handle Service Bus Namespace options. custom_name = To override default resource name, generated if not set. sku = Defines which tier to use. Options are Basic, Standard or Premium. capacity = Specifies the capacity. When SKU is Premium, capacity can be 1, 2, 4, 8 or 16. premium_messaging_partitions = Specifies the number messaging partitions. Only valid when sku is Premium and the minimum number is 1. Possible values include 0, 1, 2, and 4. Changing this forces a new resource to be created. local_auth_enabled = Whether or not SAS authentication is enabled for the Service Bus Namespace. zone_redundant = Whether or not this resource is zone redundant. SKU needs to be Premium. minimum_tls_version = The minimum supported TLS version for this Service Bus Namespace. public_network_access_enabled = Is public network access enabled for the Service Bus Namespace?	object({ custom_name = optional(string) sku = optional(string, "Standard") capacity = optional(number, 0) premium_messaging_partitions = optional(number, 0) local_auth_enabled = optional(bool, true) zone_redundant = optional(bool, false) minimum_tls_version = optional(string, "1.2") public_network_access_enabled = optional(bool, true) })	{}	no
