Terraform -如何查找Azure Kubernetes AKS vnet ID以进行网络对等

我使用一个Terraform脚本来部署AKS和一个应用网关，到目前为止一切都按预期运行，我需要做的最后一件事就是在AKS和应用网关之间配置vnet对等。
根据Terraform的文档，vnet对等需要AKS vnet名称和ID：

# AppGw to AKS
resource "azurerm_virtual_network_peering" "appgw_aks_peering" {
  name                      = "appgw-aks-peer"
  resource_group_name       = "my-appgw-rg"
  virtual_network_name      = azurerm_virtual_network.my_vnet.name
  remote_virtual_network_id = ???
}

# AKS to AppGw
resource "azurerm_virtual_network_peering" "aks_appgw_peering" {
  name                      = "aks-appgw-peer"
  resource_group_name       = "my-aksnode-rg"
  virtual_network_name      = ???
  remote_virtual_network_id = azurerm_virtual_network.my_vnet.id
}

resource "azurerm_kubernetes_cluster" "my_cluster" {
  name                = "my-aks"
  location            = "australiaeast"
  resource_group_name = "my-aks-rg"
  node_resource_group = "my-aksnode-rg"

  addon_profile {
    ingress_application_gateway {
      enabled    = true
      gateway_id = azurerm_application_gateway.my_appgw.id
    }
  }

  default_node_pool {
    name                 = "np01"
    node_count           = 1
    os_disk_size_gb      = 30
    vm_size              = var.aks_np_vm_sku
  }

  ...
}

问题是创建AKS时会自动创建AKS vnet，并且名称或ID都不会导出到任何地方。我找不到使用Terraform获取AKS vnet名称或ID的方法。有人能为我指出正确的方向或建议替代解决方案吗？

由于无法从AKS群集的资源块获取Vnet ID，您也可以为AKS创建一个vnet和子网，并在默认节点池块中创建群集时使用它，如下所示：

default_node_pool {
    name                 = "np01"
    node_count           = 1
    os_disk_size_gb      = 30
    vm_size              = var.aks_np_vm_sku
    vnet_subnet_id = azurerm_subnet.aks.id
  }

因此，根据您的要求，.tf文件将如下所示：

provider "azurerm" {
    features{}
}
data "azurerm_resource_group" "name" {
  name = "resourcegroupname"
}
resource "azurerm_virtual_network" "aks" {

答：只能从Kubernetes资源中获取子网ID。最好的方法是使用Terraform创建一个vnet和一个子网，并将您的Kubernetes分配到该子网。然后您可以添加对等。

# AppGw to AKS
resource "azurerm_virtual_network_peering" "appgw_aks_peering" {
  name                      = "appgw-aks-peer"
  resource_group_name       = "my-appgw-rg"
  virtual_network_name      = azurerm_virtual_network.my_vnet.name
  remote_virtual_network_id = azurerm_virtual_network.aks.id
}

# AKS to AppGw
resource "azurerm_virtual_network_peering" "aks_appgw_peering" {
  name                      = "aks-appgw-peer"
  resource_group_name       = "my-aksnode-rg"
  virtual_network_name      = azurerm_virtual_network.aks.name
  remote_virtual_network_id = azurerm_virtual_network.my_vnet.id
}

这是为那些想知道你的AKS集群属于哪个虚拟网络的读者准备的。
运行此命令，
az aks show -g portal-eu -n myhsmportaldevstage，然后在返回的JSON中查找networkProfile.vnetSubnetId。
希望这能帮上忙。
