Attaching SSL certificate to Azure application gateway in Terraform

Question

It's been somewhat long I'm trying to automate the deployment of an application gateway using Terraform but it simply fails with an error message. I have made sure all protocol settings to HTTPS. However, I doubt there is something fishy with the PFX certificate.

Is it that I'm not supplying the authentication certificate due to which it's failing? Tried a lot over the web to get a solution but there are no mentions of this.

Terraform Code:

# Create a resource group
resource "azurerm_resource_group" "rg" {
  name     = "my-rg-application-gateway-12345"
  location = "West US"
}

# Create a application gateway in the web_servers resource group
resource "azurerm_virtual_network" "vnet" {
  name                = "my-vnet-12345"
  resource_group_name = "${azurerm_resource_group.rg.name}"

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

正如所提到的azurerm_application_gateway文档 ，您需要将添加ssl_certificate_name您http_listener使用时，块https 。
