Azure Private Endpoint

This Terraform module creates an Azure Private Endpoint with one or more Azure Private DNS Zones as an option.

You can create Private DNS Zones without creating a Private Endpoint by using the submodule modules/private-dns-zone.

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.

target_resource	Private Link Service Alias or ID of the target resource.	string	n/a	yes
use_caf_naming	Use the Azure CAF naming provider to generate default resource name. Custom names override this if set. Legacy default names is used if this is set to false.	bool	true	no
use_existing_private_dns_zones	Boolean to create the Private DNS Zones corresponding to the Private Endpoint. If you wish to centralize the Private DNS Zones in another Resource Group that could belong to another subscription, set this option to true and use the private-dns-zone submodule directly.	bool	false	no
