Azure Terraform（十四）Azure Key Vault 的机密管理-526互联

一，引言

　　最近有网友私信我，将 Terraform 部署到 Azure 是一种将基础结构作为代码进行管理的好方法，但是如何使用 Azure Key Vault 来存储我们的 Secret ？在这篇博文中，我将给大家展示一下展示如何使用 Terraform 引用 Azure Key Vault Secret。

1）这个时候就有人问了，Secret 信息为什么要存储在 Azure Key Vault ?

Azure Key Vault 是在 Azure 中存储机密的好方法。它是存储和访问 Secret 的安全场所。您可以生成、存储和控制对令牌、密码、证书、API 密钥和其他秘密的访问。

让我们一起开始今天的内容来展示如何做到这一点 ?

1，使用 Terraform 创建 Azure Key Vault

让我们使用Terraform 创建一个 Key Vault

data "azurerm_resource_group" "cnbate_resource_group" {
  name = "Web_Test_TF_RG"
}


resource "azurerm_key_vault" "keyvault1" {
  name                = "cnbateblogwebkv"
  resource_group_name = data.azurerm_resource_group.cnbate_resource_group.name
  tenant_id           = data.azurerm_client_config.current.tenant_id
  sku_name            = "standard"
  location            = data.azurerm_resource_group.cnbate_resource_group.location
  access_policy {
    tenant_id = data.azurerm_client_config.current.tenant_id
    object_id = data.azurerm_client_config.current.object_id

    secret_permissions = [
      "Get",
      "List",
      "Set",
      "Delete"
    ]
  }
}

2，使用 Terraform 和 Azure CLI 创建 Secret

Terraform：

resource "azurerm_key_vault_secret" "keyvault_secret1" {
  name         = "Name1"
  value        = "cnbatelisi"
  key_vault_id = azurerm_key_vault.kv.id
}

使用 Azure CLI 创建第二个 Key Vault 机密

az keyvault secret set --vault-name cnabteblogwebkv --name Name2 --value cnbatewangwu

下面创建的两个 Secret ：

3，引用 Terraform 中的两个秘密

在这个例子中，我在上面添加了两个 Secret 。我现在将展示如何在 Terraform 中引用它们。

第一个将根据 Terraform 创建的 Secret 创建一个 Storage Account。第二个将根据 Azure CLI 创建的机密创建一个存储帐户。

resource "azurerm_storage_account" "storage_account1" {
  name                     = azurerm_key_vault_secret.keyvault_secret1.value
  resource_group_name      = data.azurerm_resource_group.cnbate_resource_group.name
  location                 = data.azurerm_resource_group.cnbate_resource_group.location
  account_tier             = "Standard"
  account_replication_type = "LRS"

  depends_on = [
    data.azurerm_resource_group.cnbate_resource_group,
    azurerm_key_vault_secret.keyvault_secret1
  ]
}

对于第二个示例，我将使用 datasource 来引用 Azure CLI 创建的 keyvault_secret2

data "azurerm_key_vault_secret" "keyvault_secret2" {

name = "Name2"

key_vault_id = azurerm_key_vault.keyvault1.id

}

resource "azurerm_storage_account" "storage_account2" {

name = data.azurerm_key_vault_secret.keyvault_secret2.value

resource_group_name = data.azurerm_resource_group.cnbate_resource_group.name

location = data.azurerm_resource_group.cnbate_resource_group.location

account_tier = "Standard"

account_replication_type = "LRS"

depends_on = [

data.azurerm_resource_group.cnbate_resource_group

]

}

完整代码：

terraform {
  # backend "azurerm" {
  #   storage_account_name = "cnbatestorestatefile004"
  #   container_name       = "terraform-state"
  #   key                  = "cnbate.terraform.stats"
  # }

  required_providers {
    azurerm = {
    }
  }
}

provider "azurerm" {
  features {}
}

locals {
  location_eastAsia = "East Asia"
}

data "azurerm_client_config" "current" {

}

data "azurerm_resource_group" "cnbate_resource_group" {
  name = "Web_Test_TF_RG"
}


resource "azurerm_key_vault" "keyvault1" {
  name                = "cnbateblogwebkv"
  resource_group_name = data.azurerm_resource_group.cnbate_resource_group.name
  tenant_id           = data.azurerm_client_config.current.tenant_id
  sku_name            = "standard"
  location            = data.azurerm_resource_group.cnbate_resource_group.location
  access_policy {
    tenant_id = data.azurerm_client_config.current.tenant_id
    object_id = data.azurerm_client_config.current.object_id

    secret_permissions = [
      "Get",
      "List",
      "Set",
      "Delete"
    ]
  }
}

resource "azurerm_key_vault_secret" "keyvault_secret1" {
  name         = "Name1"
  value        = "cnbatelisi"
  key_vault_id = azurerm_key_vault.keyvault1.id
}


resource "azurerm_storage_account" "storage_account1" {
  name                     = azurerm_key_vault_secret.keyvault_secret1.value
  resource_group_name      = data.azurerm_resource_group.cnbate_resource_group.name
  location                 = data.azurerm_resource_group.cnbate_resource_group.location
  account_tier             = "Standard"
  account_replication_type = "LRS"

  depends_on = [
    data.azurerm_resource_group.cnbate_resource_group,
    azurerm_key_vault_secret.keyvault_secret1
  ]
}

data "azurerm_key_vault_secret" "keyvault_secret2" {
  name         = "Name2"
  key_vault_id = azurerm_key_vault.keyvault1.id
}

resource "azurerm_storage_account" "storage_account2" {
  name                     = data.azurerm_key_vault_secret.keyvault_secret2.value
  resource_group_name      = data.azurerm_resource_group.cnbate_resource_group.name
  location                 = data.azurerm_resource_group.cnbate_resource_group.location
  account_tier             = "Standard"
  account_replication_type = "LRS"

  depends_on = [
    data.azurerm_resource_group.cnbate_resource_group
  ]
}
