Question

我正在创建一个Azure逻辑应用程序（使用它解压缩到Blob存储）。为此，我需要Logic App工作流程以及与Blob存储的连接。我使用Terraform创建空的Logic App工作流，并使用Visual Studio创建实际的Logic App实现，然后将其部署到使用tf创建的Logic App。

我使用以下tf代码创建空的Logic App工作流：

resource "azurerm_logic_app_workflow" "logic_unzip" {                    
  name                    = "ngh-${var.deployment}-unziplogic"     
  resource_group_name     = "${azurerm_resource_group.rg.name}"    
  location                = "${azurerm_resource_group.rg.location}"
}

由于Logic App需要连接到Blob存储，因此我将使用以下模板来创建它：

resource "azurerm_template_deployment" "depl_connection_azureblob" {                                                                               
        name                    = "azureblob"                                                                                                      
        resource_group_name     = "${azurerm_resource_group.rg.name}"

                "api_id"                = "${data.azurerm_subscription.current.id}/providers/Microsoft.Web/locations/${azurerm_resource_group.rg.location}/managedApis/azureblob"                                                                                                                     
        }                                                                                                                                          
        deployment_mode         = "Incremental"                                                                                                    
}

运行计划和应用，这些效果完美。然后，在Visual Studio中，我可以创建Logic App，并使用azureblob连接选择正确的Blob存储。

现在，当我从Visual Studio部署Logic App Workflow并运行terraform plan时，我将进行以下更改：

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

  ~ azurerm_logic_app_workflow.logic_unzip
      parameters.$connections: "" => ""
      parameters.%:            "1" => "0"


Plan: 0 to add, 1 to change, 0 to destroy.

现在运行apply命令将在删除绑定的连接时断开Logic App。显然，Visual Studio部署已在Logic App和连接之间创建了绑定。

如何告诉Terraform不要从Logic App中删除连接（由Visual Studio部署创建）？

Answer 1

Terraform不知道在arm模板中部署的资源，因此它检测到状态更改并尝试“修复”该更改。我没有看到用于逻辑应用程序连接的任何CF资源，因此看到它如何检测参数。将连接从0更改为1可以将您的连接直接添加到工作流资源中可能有效，但是CF提到：{{ 1}}，但我看不到架构中的连接，这有点奇怪，但是我认为我误读了架构

您还可以使用ignore_changes：

Any parameters specified must exist in the Schema defined in workflow_schema
