Azure Regions and Availability Zones module

This module provides an output of all Azure regions and availability zones.

The module outputs a list of objects with the following attributes:

• name - The name of the region. E.g. "eastus"
• display_name - The display name of the region. E.g. "East US".
• paired_region_name - The name of the region paired with this region. May be null if the region has no pair.
• geography - The geography of the region.
• geography_group - The geography group of the region.
• zones - A list of the availability zones in the region. Will be empty if the region does not support zones.

This data is the further composed into useful maps keyed by region name and region display name.

Usage

module "regions" {
  source = "Azure/regions/azurerm"
  version = "<version>" # change this to your desired version, https://www.terraform.io/language/expressions/version-constraints
}

output "regions" {
  value = module.regions.regions
}

Optional Inputs

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

recommended_regions_only

Description: If true, the module will only return regions that are have the category set to Recommended by the locations API.

Type: bool

Default: true

use_cached_data

Description: If true, the module will use cached data from the data directory. If false, the module will use live data from the Azure API.

The default is true to avoid unnecessary API calls and provide a guaranteed consistent output.
Set to false to ensure the latest data is used.

Using data from the Azure APIs means that if the API response changes, then the module output will change.
This may affect deployed resources that rely on this data.

Type: bool

Default: true

• geography - The geography of the region.
• geography_group - The geography group of the region.
• zones - A list of the availability zones in the region. Will be empty if the region does not support zones.
