查看预订或未来预留请求

本文档介绍了如何查看预订或未来预订请求。如需详细了解不同类型的预配，请参阅预配类型。

查看预订或未来预留请求时，您可以执行以下操作：

查看预留设置。此审核有助于您验证预订的详细信息，确保其符合您的需求，并规划容量。
确定可消耗实例的数量。此检查可帮助您确定有多少个 Compute Engine 实例可以使用您的预留容量。

限制

您只能在创建共享预留或共享未来预留请求的项目中查看这些预留或请求。

准备工作

如果您尚未设置身份验证，请进行设置。身份验证是通过其进行身份验证以访问 Google Cloud 服务和 API 的过程。如需从本地开发环境运行代码或示例，您可以通过选择以下选项之一向 Compute Engine 进行身份验证：

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. Install the Google Cloud CLI, then initialize it by running the following command:
  gcloud init
  Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
2. Set a default region and zone.

所需的角色

如需获得查看预留或未来预留请求所需的权限，请让您的管理员为您授予项目的 Compute Admin (roles/compute.admin) IAM 角色。如需详细了解如何授予角色，请参阅管理对项目、文件夹和组织的访问权限。

此预定义角色包含查看预留或未来预留请求所需的权限。如需查看所需的确切权限，请展开所需权限部分：

所需权限

如需查看预留或未来预留请求，您需要具备以下权限：

项目的 compute.reservations.list 权限（查看预留列表）
项目的 compute.futureReservations.list 权限（查看未来预留请求的列表）
项目的 compute.reservations.get 权限（查看预留的详细信息）
项目的 compute.futureReservations.get 权限（查看未来预留请求的详细信息）

您也可以使用自定义角色或其他预定义角色来获取这些权限。

查看预订设置

以下部分介绍了如何查看预订或未来预订请求的设置。

查看预留

如需查看一个或多个预留的设置，请使用本部分中介绍的以下方法之一：

如需大致了解项目中的所有预留，请查看预留列表。
如需查看单个预订的完整详情，请查看该预订的详情。

如需查看预订中的 deleteAtTime 和 reservationSharingPolicy 字段（预览），请使用 Google Cloud CLI 查看预订的详细信息，或使用 REST API 查看预订。如果您不需要这些字段，请选择以下任一选项查看预订：

控制台

在 Google Cloud 控制台中，转到预留页面。

转到“预留”

在按需预留标签页（默认）上，表格会列出每个预留，表格中的每列描述一个属性。
可选：在按需预订表格中，执行以下一项或两项操作：
- 如需显示预订的有保证的数量，请点击 Column display options...（列显示选项...），选中 Assured count（有保证的数量）复选框，然后点击 OK（确定）。
- 如需优化预订列表，请在 Filter 字段中，选择要按其过滤预订的属性。
如需查看预留的详细信息，请在名称列中点击相应预留的名称。系统会打开一个页面，其中包含预订的详细信息。

gcloud

如需查看预留列表，请使用 gcloud compute reservations list 命令：

gcloud compute reservations list

输出类似于以下示例：

NAME: r-01
IN_USE_COUNT: 0
COUNT: 5
ZONE: us-central1-a
SHARE_TYPE: LOCAL

NAME: r-02
IN_USE_COUNT: 3
COUNT: 10
ZONE: us-central1-f
SHARE_TYPE: LOCAL

（可选）如需使用过滤表达式优化预订列表，请添加 --filter 标志：

gcloud compute reservations list \
    --filter="FILTER_EXPRESSION"

将 FILTER_EXPRESSION 替换为过滤表达式。

如需查看预留的详细信息，请使用 gcloud compute reservations describe 命令：

gcloud compute reservations describe RESERVATION_NAME \
    --zone=ZONE

替换以下内容：

RESERVATION_NAME：现有预留的名称。
ZONE：预留所在的可用区。

输出类似于以下示例：

creationTimestamp: '2024-10-11T03:25:23.192-07:00'
id: '4488228526648280060'
kind: compute#reservation
name: r-01
selfLink: https://www.googleapis.com/compute/v1/projects/my-project/zones/us-central1-a/reservations/r-01
shareSettings:
  shareType: LOCAL
specificReservation:
  assuredCount: '50'
  count: '50'
  inUseCount: '25'
  instanceProperties:
    machineType: n2-standard-2
specificReservationRequired: false
status: READY
zone: https://www.googleapis.com/compute/v1/projects/my-project/zones/us-central1-a

查看未来预留请求

如需查看一个或多个未来预留请求的设置，请使用本部分中介绍的以下方法之一：

如需大致了解项目中的所有未来预留请求，请查看请求列表。
如需查看单个未来预留请求的完整详细信息，请查看该请求的详细信息。

如需查看未来预留请求，请选择以下选项之一：

控制台

在 Google Cloud 控制台中，转到预留页面。

转到“预留”
点击未来预留标签页。

该表会列出每个未来预留请求，每列描述一个属性。
可选：如需优化请求列表，请在 Filter 字段中，选择要按其过滤请求的属性。
如需查看请求的详细信息，请在名称列中点击相应请求的名称。系统随即会打开一个页面，其中包含未来预留请求的详细信息。

gcloud

如需查看未来预留请求列表，请使用 gcloud beta compute future-reservations list 命令：

gcloud beta compute future-reservations list

输出类似于以下示例：

（可选）如需使用过滤表达式优化未来预留请求列表，请添加 --filter 标志：

gcloud beta compute future-reservations list \
    --filter="FILTER_EXPRESSION"

将 FILTER_EXPRESSION 替换为过滤表达式。

如需查看未来预留请求的详细信息，请使用 gcloud beta compute future-reservations describe 命令：

gcloud beta compute future-reservations describe FUTURE_RESERVATION_NAME \
    --zone=ZONE

替换以下内容：

FUTURE_RESERVATION_NAME：现有未来预留请求的名称。
ZONE：未来预留请求所在的可用区。

确定可消耗实例的数量

如需确定可以使用预留容量的计算实例数量，请执行以下操作之一：

如需查看可以消耗预留的实例数量上限，请参阅预留中的可消耗实例。
如需查看 Compute Engine 计划在未来预留请求的开始时间为其预留的实例数量，请参阅未来预留请求中的可消耗实例。

预订中的可消耗实例

查看预留的详细信息时，您可以通过查看以下字段，了解有多少计算实例正在使用预留，以及有多少实例可以使用预留：

保证的数量 (assuredCount)：在预留的可用区内实际预留的实例数量。此数量包括为您的项目预留的实例，以及与之共享共享预留的任何项目的实例。
总数 (count)：预订中指定的预留实例数量。此数字应与保证的数量一致。

注意：如果保证的数量低于总数量，则预留的实例数量会少于预期。如需排查此问题，请参阅可供使用的虚拟机数量减少。
正在使用的机器 (inUseCount)：您的项目或共享预留的项目中正在使用预留的正在运行实例的数量。

例如，如果保证数量 (assuredCount) 和总数量 (count) 均为 50，且使用预留的实例数量 (inUseCount) 为 25，则在预留完全耗尽之前，还可以有 25 个实例使用该预留。

未来预留请求中的可消耗实例

您可以确定 Compute Engine 在未来预留请求的开始时间为哪些计算实例创建预留。对于草稿、待审批或已批准的请求，您可以按如下方式确定此编号：

查看您的项目以及与请求共享的任何项目中与请求属性匹配的正在运行的实例和未使用的预留数量。
从请求中的总数中减去匹配的正在运行的实例和未使用的预留数量。

您可以一次性确定单个或多个请求的可消耗实例数量。对于多个请求，请使用 Google Cloud 控制台或 REST API。对于单个请求，请选择以下任一选项：

控制台

在 Google Cloud 控制台中，转到预留页面。

转到“预留”
点击未来预留标签页。

该表会列出每个未来预留请求，每列描述一个属性。
如需确定 Compute Engine 计划在请求的开始时间为其预留的实例数量，请从总计数列中减去匹配的数量列。

匹配的数量列会显示以下警告之一：
- 匹配数量为零：您的项目或与您的请求共享的任何项目中都没有匹配的正在运行的实例或未使用的预留。
- 匹配数量等于总数量：Compute Engine 不会在请求开始时为其预留任何实例。
如果您修改请求，或创建与请求匹配的新实例或预留，则 Compute Engine 会在 30 分钟内更新“匹配数量”列。
可选：如需查看请求中的匹配的数量列上次更新的时间，请执行以下操作：
1. 在名称列中，点击相应请求的名称。系统会打开一个页面，其中包含未来预留请求的详细信息。
2. 在资源详情部分中，查看上次匹配用法评估时间字段。

gcloud

如需查看未来预留请求的详细信息，请使用 gcloud beta compute future-reservations describe 命令：

gcloud beta compute future-reservations describe FUTURE_RESERVATION_NAME \
    --zone=ZONE

替换以下内容：

FUTURE_RESERVATION_NAME：现有未来预留请求的名称。
ZONE：未来预留请求所在的可用区。

在输出中，找到 count 和 totalCount 字段：

...
specificSkuProperties:
  ...
  totalCount: '100'
status:
  existingMatchingUsageInfo:
    count: '50'
    timestamp: '2025-03-30T01:00:00Z'
  ...
  procurementStatus: DRAFTING
...

从 totalCount 中减去 count 的值。例如，如果 count 为 50，totalCount 为 100，则 Compute Engine 会在请求开始时间自动为 50 个实例创建预留。

如果您修改请求，或者创建与请求匹配的新实例或预留，Compute Engine 会在 30 分钟内更新 existingMatchingUsageInfo 字段。如需验证此字段的上次更新时间，请检查 existingMatchingUsageInfo.timestamp 的值。

REST

如需查看未来预留请求列表，请向 Beta 版 futureReservations.list 方法发出 GET 请求。在请求网址中添加 filter 查询参数，并指定仅显示 name、specificSkuProperties 和 status 字段：

GET https://compute.googleapis.com/compute/beta/projects/PROJECT_ID/zones/ZONE/futureReservations?fields=items.name,items.specificSkuProperties,items.status

替换以下内容：

PROJECT_ID：您创建未来预留请求的项目的 ID。
ZONE：未来预留请求所在的可用区。

在输出中，找到每个草稿、待审批请求或已批准请求的 count 和 totalCount 字段：

{
  "items": [
    {
      "specificSkuProperties": {
        ...
        totalCount: "100"
      },
      "name": "fr-01",
      "status": {
        "procurementStatus": "APPROVED",
        ...
        existingMatchingUsageInfo: {
          count: "50",
          "timestamp": "2025-01-22T07:54:26.295Z"
        }
      }
    },
    {
      "specificSkuProperties": {
        ...
        totalCount: "20"
      },
      "name": "fr-02",
      "status": {
        "procurementStatus": "DRAFTING",
        ...
        existingMatchingUsageInfo: {
          "count": "2",
          "timestamp": "2025-01-22T07:54:26.295Z"
        }
      }
    }
  ]
}

对于每个请求，请从 totalCount 中减去 count 的值。例如，如果 count 为 50，totalCount 为 100，则 Compute Engine 会在请求开始时间自动为 50 个实例创建预留。

如果您修改请求，或创建与请求匹配的新实例或预留，Compute Engine 会在 30 分钟内更新 existingMatchingUsageInfo 字段。如需验证此字段的上次更新时间，请检查 existingMatchingUsageInfo.timestamp 的值。
