查看 VM 詳細資料


本文說明如何查看現有虛擬機器 (VM) 執行個體的詳細資料。

查看 VM 詳細資料有助於瞭解其設定和狀態,例如已連結的磁碟、建立時間戳記、機器類型和 VM ID。您可以使用這個 ID 透過不可變的值參照 VM。

事前準備

  • 如果尚未設定,請先設定驗證機制。驗證是指驗證身分,以便存取 Google Cloud 服務和 API 的程序。如要在本機開發環境中執行程式碼或範例,您可以選取下列任一選項,向 Compute Engine 進行驗證:

    Select the tab for how you plan to use the samples on this page:

    Console

    When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

    gcloud

    1. After installing the Google Cloud CLI, initialize it by running the following command:

      gcloud init

      If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

    2. Set a default region and zone.

    REST

    To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

      After installing the Google Cloud CLI, initialize it by running the following command:

      gcloud init

      If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

    For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

必要的角色

如要取得查看 VM 詳細資料所需的權限,請要求管理員為您授予 VM 或專案的 Compute Instance 管理員 (v1) (roles/compute.instanceAdmin.v1) IAM 角色。如要進一步瞭解如何授予角色,請參閱「管理專案、資料夾和機構的存取權」。

這個預先定義的角色包含 compute.instances.get 權限,這是查看 VM 詳細資料所需的權限。

您或許還可透過自訂角色或其他預先定義的角色取得此權限。

查看 VM 詳細資料

如要查看 VM 的詳細資料,請選取下列任一選項:

主控台

  1. 前往 Google Cloud 控制台的「VM instances」(VM 執行個體) 頁面

    前往 VM 執行個體

  2. 在「VM 執行個體」頁面中,您可以查看運算執行個體的下列資訊:

    • 執行個體的名稱。
    • 執行個體所在的區域。
    • 執行個體使用的機器類型。
    • 佈建模式,指出是否將執行個體建立為 Spot VM
    • 適用於執行個體的任何最佳化建議。
    • VM 執行個體是否屬於執行個體群組
    • 執行個體使用的 IP 位址。

    上方清單包含「VM instances」頁面上顯示的預設欄。您可以按一下 「資料欄顯示選項」,變更每個 VM 顯示的資料欄。

  3. 在「Name」欄中,按一下 VM 名稱,查看 VM 執行個體的其他詳細資料。

gcloud

如要查看 VM 的詳細資料,請使用 gcloud compute instances describe 指令

gcloud compute instances describe VM_NAME \
    --zone=ZONE

更改下列內容:

  • VM_NAME:VM 名稱。

  • ZONE:VM 所在區域。

輸出結果會與下列內容相似:

REST

如要查看 VM 的詳細資料,請對 instances.get 方法發出 GET 要求。

GET https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/VM_NAME

更改下列內容:

  • PROJECT_ID:VM 所在專案的 ID。

  • ZONE:VM 所在區域。

  • VM_NAME:VM 名稱。

決定執行個體的 CPU 和記憶體配置

您可以根據執行個體使用的機器類型,判斷要為該執行個體分配多少 CPU 和記憶體,例如:

  • c3-standard-22:C3 是機器系列名稱,standard 是執行個體的記憶體配置類型,22 是分配給執行個體的 vCPU 數量。通常,standard 機器類型會以每個 vCPU 4 GB 記憶體的比例使用記憶體。因此,這個機器類型會有 88 GB 的 RAM。

    standardhighmemhighcpuultamemmegamem 機器類型的記憶體/CPU 比率,在各機器系列之間可能略有差異,因此請參閱機器系列頁面,瞭解各機器類型所分配的確切記憶體量。

  • n2-custom-8-16384:對於自訂機器類型,機器類型的前半部是機器系列,但 N1 機器類型除外,因為它完全不包含機器系列。custom 後面的前一個數字是 vCPU 數量,最後一個數字是分配給執行個體的記憶體量 (以 MB 為單位)。

如要進一步瞭解機器類型,請參閱機器系列資源與比較指南
