how to define "azurerm_resource_group_template_deployment" "parameters_content" section

Question

I am trying to use the azurerm_resource_group_template_deployment

resource "azurerm_resource_group_template_deployment" "my-arm-template" {

  parameters_content = { 
    location            = azurerm_resource_group.my_rg.location
  }
  name                = "my_name"
   ...
}

I am getting an error:

Inappropriate value for attribute "parameters_content": string required.

How should I define the parameters_content section?

Answer 1

You need to jsonencode the actual argument, like

resource "azurerm_resource_group_template_deployment" "my-arm-template" {

  parameters_content = jsonencode({ 
    location = azurerm_resource_group.my_rg.location
  })
   ...
}

I had the exact same issue and luk2302 sent me on the right track, but it needed a slight change to his answer. Thanks for your help luk2302!

The correct answer to this is:

resource "azurerm_resource_group_template_deployment" "my_template_resource_name" {
  name                = var.my_friendly_name
  resource_group_name = azurerm_resource_group.my_rg.name

  template_content = file("template_name.json")

  parameters_content = jsonencode({ 
     "location" = {
        value = azurerm_resource_group.my_rg.location
     }
     "variable2" = {
        value = var.variable2
      }
  })

  deployment_mode = "Incremental"
}
