Azure AKS Terraform-如何指定虚拟机大小

在我的Azure订阅中，我试图使用Terraform创建一个AKS集群。 我的main.tf如下所示：

## Azure resource provider ##
provider "azurerm" {
  version = "=1.36.1"
}

## Azure resource group for the kubernetes cluster ##
resource "azurerm_resource_group" "aks_demo" {
  name     = var.resource_group_name
  location = var.location
}

## AKS kubernetes cluster ##
resource "azurerm_kubernetes_cluster" "aks_demo" { 
  name                = var.cluster_name
  resource_group_name = azurerm_resource_group.aks_demo.name
  location            = azurerm_resource_group.aks_demo.location
  dns_prefix          = var.dns_prefix

  linux_profile {
    admin_username = var.admin_username

    ## SSH key is generated using "tls_private_key" resource
    ssh_key {
      key_data = "${trimspace(tls_private_key.key.public_key_openssh)} ${var.admin_username}@azure.com"
    }
  }

  agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = "Standard_D2"
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

  service_principal {
    client_id     = var.client_id
    client_secret = var.client_secret
  }

  tags = {
    Environment = "Production"
  }
}

## Private key for the kubernetes cluster ##
resource "tls_private_key" "key" {
  algorithm   = "RSA"
}

## Save the private key in the local workspace ##
resource "null_resource" "save-key" {
  triggers = {
    key = tls_private_key.key.private_key_pem
  }

  provisioner "local-exec" {
    command = <<EOF
      mkdir -p ${path.module}/.ssh
      echo "${tls_private_key.key.private_key_pem}" > ${path.module}/.ssh/id_rsa
      chmod 0600 ${path.module}/.ssh/id_rsa
EOF
  }
}

## Outputs ##

# Example attributes available for output
output "id" {
    value = "${azurerm_kubernetes_cluster.aks_demo.id}"
}

output "client_key" {
  value = "${azurerm_kubernetes_cluster.aks_demo.kube_config.0.client_key}"
}

output "client_certificate" {
  value = "${azurerm_kubernetes_cluster.aks_demo.kube_config.0.client_certificate}"
}

output "cluster_ca_certificate" {
  value = "${azurerm_kubernetes_cluster.aks_demo.kube_config.0.cluster_ca_certificate}"
}

output "kube_config" {
  value = azurerm_kubernetes_cluster.aks_demo.kube_config_raw
}

output "host" {
  value = azurerm_kubernetes_cluster.aks_demo.kube_config.0.host
}

output "configure" {
  value = <<CONFIGURE
Run the following commands to configure kubernetes client:
$ terraform output kube_config > ~/.kube/aksconfig
$ export KUBECONFIG=~/.kube/aksconfig
Test configuration using kubectl
$ kubectl get nodes
CONFIGURE
}

## Azure config variables ##
variable "client_id" {}

variable "client_secret" {}

variable location {
  default = "Central US"
}

## Resource group variables ##
variable resource_group_name {
  default = "aksdemo-rg"
}


## AKS kubernetes cluster variables ##
variable cluster_name {
  default = "aksdemo1"
}

  variable "vm_size" {
  default = "Standard_A0"
  }

variable "agent_count" {
  default = 3
}

variable "dns_prefix" {
  default = "aksdemo"
}

variable "admin_username" {
    default = "demo"
}

当我运行terraform apply时，会出现以下错误：

    Error: Error creating Managed Kubernetes Cluster "aksdemo1" (Resource Group "aksdemo-rg"): 

containerservice.ManagedClustersClient#CreateOrUpdate: Failure sending request: StatusCode=400 --

这让我感到困惑，因为显然有一个名为vm_size的变量

要使其工作，我可以更改哪些内容？

错误消息告诉您正在尝试使用虚拟机大小，或者虚拟机类型（如果愿意），但该位置的订阅不可用，它还提供您可以选择的所有虚拟机大小

请注意，您可能复制粘贴了以下内容：

agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = "Standard_D2"
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

虚拟机大小在那里是硬编码的，因此默认的

Standard_A0

值未被提取。

---

这里的调试方法不止一种，首先我要确保使用了正确的值，然后更改VM类型以查看其是否有效。

在这里调试的方法不止一种，首先我要确保使用了正确的值，然后更改VM类型以查看是否有效。

从您提供的代码和收到的错误中可以看出，您在代码中犯了错误

您编写的代码：

agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = "Standard_D2"
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

当您将变量用于VM大小时，应该是这样的：

  agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = var.vm_size
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

虚拟机的大小应该适合您自己和需求。例如，正如在.

中所示，从您提供的代码和得到的错误中我看到，您在代码中犯了错误

您编写的代码：

agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = "Standard_D2"
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

  agent_pool_profile {
    name        = "default"
    count           = var.agent_count
    vm_size         = var.vm_size
    os_type         = "Linux"
    os_disk_size_gb = 30
  }

虚拟机的大小应该适合您自己和需求。例如，正如图中所示
