A map of private endpoints to create on this resource. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.

- `name` - (Optional) The name of the private endpoint. One will be generated if not set.
- `role_assignments` - (Optional) A map of role assignments to create on the private endpoint. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time. See `var.role_assignments` for more information.
- `lock` - (Optional) The lock level to apply to the private endpoint. Default is `None`. Possible values are `None`, `CanNotDelete`, and `ReadOnly`.
- `tags` - (Optional) A mapping of tags to assign to the private endpoint.
- `subnet_resource_id` - The resource ID of the subnet to deploy the private endpoint in.
- `private_dns_zone_group_name` - (Optional) The name of the private DNS zone group. One will be generated if not set.
- `private_dns_zone_resource_ids` - (Optional) A set of resource IDs of private DNS zones to associate with the private endpoint. If not set, no zone groups will be created and the private endpoint will not be associated with any private DNS zones. DNS records must be managed external to this module.
- `application_security_group_resource_ids` - (Optional) A map of resource IDs of application security groups to associate with the private endpoint. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.
- `private_service_connection_name` - (Optional) The name of the private service connection. One will be generated if not set.
- `network_interface_name` - (Optional) The name of the network interface. One will be generated if not set.
- `location` - (Optional) The Azure location where the resources will be deployed. Defaults to the location of the resource group.
- `resource_group_name` - (Optional) The resource group where the resources will be deployed. Defaults to the resource group of this resource.
- `ip_configurations` - (Optional) A map of IP configurations to create on the private endpoint. If not specified the platform will create one. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.
  - `name` - The name of the IP configuration.
  - `private_ip_address` - The private IP address of the IP configuration.

  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'.
  - `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.
