Terraform to create Appinsight Named value from Keyvault while creating the APIM ligger

[vivuu1989]

Is there an existing issue for this?

• [X] I have searched the existing issues

Community Note

We have below terraform code to create AzureAPIM logger configuration for the appinsight during the appinsight creation itself. But here we are facing challenge to configure the Appinsight Instrumentation Key as named value from one of existing keyvault.

Looking for both the appinsight and logger addition with namedvalue of instrumentation key (from kv) as part of the application insight creation itself and not through manual task of creating secret in Keyvault after creating the Appinsight.

Terraform Version

1.2

AzureRM Provider Version

          tags,
          disable_ip_masking

      }
    }

    resource "azurerm_api_management_logger" "logger" {
      count = var.add_to_apim ? 1 : 0

      api_management_name = var.apim_name
      resource_group_name = var.apim_rg
      name                = azurerm_application_insights.appinsights.name
      resource_id         = azurerm_application_insights.appinsights.id

      application_insights {
        instrumentation_key = azurerm_application_insights.appinsights.instrumentation_key
      }

      lifecycle {
        ignore_changes = [

Hi @vivuu1989 , thanks for submitting this! Do you mean to reference the Key Vault Secret in the azurerm_api_management_logger.application_insights.instrumentation_key field, for example in below code:

resource "azurerm_key_vault_secret" "example" {
  name         = "examplesecret"
  value        = azurerm_application_insights.appinsights.instrumentation_key
  key_vault_id = azurerm_key_vault.example.id
}
# additional access policy is needed
resource "azurerm_api_management_logger" "logger" {
   ...
  application_insights {
    instrumentation_key = azurerm_application_insights.appinsights.instrumentation_key
  }
}

Or if it is not, could you please provide more context, is there any docs for the use cases? Thanks.

hi, i had the same question, is there any way to not add 'instrumentation_key' as a string? in the azure portal, the named value can be pulled from vault directly

what i did is to create a named value

resource "azurerm_api_management_named_value" "example" {
  name                = "instrumentation-key"
  display_name        = "instrumentation-key"
...
  secret = true
  value_from_key_vault {
    secret_id = var.vault_key_secret_id
  }
}

and reference it in the logger as var (in the end, the api/terraform is doing the same, i kinda figure it out because i clicked on it in Monitoring -> Application Insights -> your_logger_name -> Instrumentation key )

resource "azurerm_api_management_logger" "example" {

...

  application_insights {
    instrumentation_key = "{{instrumentation-key}}"
  }
}
