阻止计算实例使用预留

本文档介绍了如何阻止 Compute Engine 实例使用预留。如需详细了解预留，请参阅 Compute Engine 可用区级资源的预留。

自动使用的预留可让属性与预留匹配的实例自动使用预留。如需阻止实例使用预留，请执行以下任一操作：

将实例配置为不使用预留，如本文档中所述。
创建或更新属性与预留不匹配的实例。

如果您想将实例用于测试、调试或隔离式部署等任务，可以避免使用预留。

限制

只有在实例配置为自动使用匹配的预留时，您才能更新现有实例以使其不使用预留。

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 Trusted Cloud by S3NS 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 Trusted Cloud console to access Trusted Cloud by S3NS services and APIs, you don't need to set up authentication.
gcloud

所需的角色

如需获得阻止计算实例使用预留所需的权限，请让您的管理员为您授予项目的 Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) 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。

此预定义角色可提供阻止计算实例使用预留所需的权限。如需查看所需的确切权限，请展开所需权限部分：

所需权限

阻止计算实例使用预留需要以下权限：

创建预留：项目的 compute.reservations.create 权限
创建实例：
- 针对项目的 compute.instances.create 权限
- 使用自定义映像创建虚拟机：针对映像的 compute.images.useReadOnly 权限
- 使用快照创建虚拟机：针对快照的 compute.snapshots.useReadOnly 权限
- 使用实例模板创建虚拟机：针对实例模板的 compute.instanceTemplates.useReadOnly 权限
- 为虚拟机分配旧版网络：针对项目的 compute.networks.use 权限
- 为虚拟机指定静态 IP 地址：针对项目的 compute.addresses.use 权限
- 使用旧版网络时为虚拟机分配外部 IP 地址：针对项目的 compute.networks.useExternalIp 权限
- 为虚拟机指定子网：针对项目或所选子网的 compute.subnetworks.use 权限
- 在使用 VPC 网络时为虚拟机分配外部 IP 地址：针对项目或所选子网的 compute.subnetworks.useExternalIp 权限
- 为虚拟机设置虚拟机实例元数据：针对项目的 compute.instances.setMetadata 权限
- 为虚拟机设置标记：针对虚拟机的 compute.instances.setTags 权限
- 为虚拟机设置标签：针对虚拟机的 compute.instances.setLabels 权限
- 为虚拟机设置要使用的服务账号：针对虚拟机的 compute.instances.setServiceAccount 权限
- 为虚拟机创建新磁盘：针对项目的 compute.disks.create 权限
- 以只读或读写模式挂接现有磁盘：针对磁盘的 compute.disks.use 权限
- 以只读模式挂接现有磁盘：针对磁盘的 compute.disks.useReadOnly 权限
创建实例模板：针对项目的 compute.instanceTemplates.create 权限

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。

阻止使用预留

如需阻止计算实例使用预留，请将其预留亲和性 (reservationAffinity) 属性设置为不使用预留。此属性用于控制实例是否可以使用匹配的预留、特定预留或不使用任何预留。

如需阻止一个或多个实例使用预留，请使用以下方法之一：

阻止在现有实例中使用
在创建实例时阻止使用
在批量创建实例时阻止使用
在创建实例模板时阻止使用

阻止在现有实例中使用

您可以更新正在运行的实例，使其不再自动使用预留。如本部分所述，您必须重启实例才能使更改生效。

如需阻止现有实例使用预留，请选择以下选项之一：

gcloud

创建一个空的 YAML 文件。
如需将实例的属性导出到您刚创建的 YAML 文件中，请使用 gcloud compute instances export 命令：
```
gcloud compute instances export INSTANCE_NAME \
    --destination=YAML_FILE \
    --zone=ZONE
```
替换以下内容：
- INSTANCE_NAME：实例的名称。
- YAML_FILE：您在上一步中创建的空 YAML 文件的路径。
- ZONE：实例所在的可用区。
在 YAML 配置文件中，将 consumeReservationType 设置为 NO_RESERVATION：
```
reservationAffinity:
  consumeReservationType: NO_RESERVATION
```
提示：为避免出现 "ERROR: (gcloud.compute.instances.update-from-file) Cannot parse YAML: [Expected type for field value, found True (type )]" 等错误，请在导出的实例配置文件中将 yes 或 no 的任何标签值用英文引号 (' ') 括起来。这表示这些值是字符串，而不是布尔值。
如需更新实例并重启它，请使用 gcloud compute instances update-from-file 命令，并将 --most-disruptive-allowed-action 标志设置为 RESTART：
```
gcloud compute instances update-from-file INSTANCE_NAME \
    --most-disruptive-allowed-action=RESTART \
    --source=YAML_FILE \
    --zone=ZONE
```
替换以下内容：
- INSTANCE_NAME：实例的名称。
- YAML_FILE：包含您在上一步中修改的配置数据的 YAML 文件的路径。
- ZONE：实例所在的可用区。

REST

如需查看现有实例的属性，请向 instances.get 方法发出 GET 请求：
```
GET https://compute.s3nsapis.fr/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/INSTANCE_NAME
```
替换以下内容：
- PROJECT_ID：您在其中创建实例的项目的 ID。
- ZONE：实例所在的可用区。
- INSTANCE_NAME：实例的名称。
将 GET 请求的输出存储在文件或文本编辑器中。修改复制的输出，将 consumeReservationType 字段更改为 NO_RESERVATION：
```
{
  ...
  "reservationAffinity": {
    "consumeReservationType": "NO_RESERVATION"
  },
  ...
}
```
如需更新实例并重启它，请向 instances.update 方法发出 PUT 请求。在请求中，执行以下操作：
- 在请求网址中，添加 mostDisruptiveAllowedAction 查询参数并设置为 RESTART。
- 对于请求正文，请使用您在上一步中修改的 GET 请求的输出。
请求类似于以下示例：
```
PUT https://compute.s3nsapis.fr/compute/v1/projects/example-project/zones/us-central-1/instances/instance-01?mostDisruptiveAllowedAction=RESTART

{
  ...
  "reservationAffinity": {
    "consumeReservationType": "NO_RESERVATION"
  },
  ...
}
```

如需详细了解如何更新实例，请参阅更新实例属性。

在创建实例时阻止使用

如需创建无法使用预留的计算实例，请选择以下选项之一：

控制台

在 Trusted Cloud 控制台中，前往创建实例页面。

转到“创建实例”
在名称字段中，输入实例的名称。
在区域和可用区列表中，选择要在其中创建实例的区域和可用区。
指定用于实例的机器类型。
在导航菜单中，点击高级。
在预留部分中，选择不使用预留。
点击创建。

gcloud

如需创建无法使用预留的实例，请使用 gcloud compute instances create 命令，并将 --reservation-affinity 标志设置为 none：

gcloud compute instances create INSTANCE_NAME \
    --machine-type=MACHINE_TYPE \
    --reservation-affinity=none \
    --zone=ZONE

替换以下内容：

INSTANCE_NAME：实例的名称。
MACHINE_TYPE：用于实例的机器类型。
ZONE：要创建实例的可用区。

Go

替换以下内容：

PROJECT_ID：您要在其中创建实例的项目的 ID。
ZONE：要创建实例的可用区。
INSTANCE_NAME：实例的名称。
MACHINE_TYPE：用于实例的机器类型。
IMAGE_PROJECT：包含操作系统映像的映像项目；例如 debian-cloud。如需详细了解支持的映像项目，请参阅公共映像。
IMAGE：指定以下其中一项：
- 操作系统映像的特定版本；例如 debian-12-bookworm-v20240617。
- 映像系列，其格式必须为 family/IMAGE_FAMILY。此项指定最新的未弃用操作系统映像。例如，如果您指定 family/debian-12，则系统会使用 Debian 12 映像系列中的最新版本。如需详细了解如何使用映像系列，请参阅映像系列最佳实践。

在创建实例模板时阻止使用

创建实例模板以将实例配置为不使用预留后，您可以使用该模板执行以下操作：

执行以下操作时，阻止托管式实例组 (MIG) 中的计算实例使用预留：
- 创建 MIG
- 在 MIG 中应用新的实例配置
创建不使用预留的实例

如需创建实例模板以将实例配置为不使用预留，请选择以下选项之一：

控制台

在 Trusted Cloud 控制台中，前往创建实例模板页面。

前往创建实例模板
在名称字段中，输入实例模板的名称。
在位置部分中，指定您要创建区域级（默认）实例模板还是全球实例模板。
在机器配置部分中，指定要用于使用该模板创建的实例的机器类型。
展开高级选项部分，然后执行以下操作：
1. 展开管理部分。
2. 在预留部分中，选择不使用预留。
点击创建。

gcloud

如需创建实例模板以将实例配置为不使用预留，请使用 gcloud compute instances-templates create 命令，并将 --reservation-affinity 标志设置为 none。

如需创建区域级实例模板以将实例配置为不使用预留，请运行以下命令。如果您要创建全球实例模板，请使用相同的命令，但不带 --instance-template-region 标志。

gcloud compute instance-templates create INSTANCE_TEMPLATE_NAME \
    --instance-template-region=REGION \
    --machine-type=MACHINE_TYPE \
    --reservation-affinity=none

替换以下内容：

INSTANCE_TEMPLATE_NAME：实例模板的名称。
REGION：要在其中创建实例模板的区域。
MACHINE_TYPE：要用于使用实例模板创建的实例的机器类型。

REST

如需创建实例模板以将实例配置为不使用预留，请向以下方法之一发出 POST 请求：

如需创建全球实例模板：instanceTemplates.insert 方法。
如需创建区域级实例模板：regionInstanceTemplates.insert 方法。

在请求正文中，添加 consumeReservationType 字段并将其设置为 NO_RESERVATION。

例如，如需创建区域级实例模板并指定不使用预留，请发出如下请求：

POST https://compute.s3nsapis.fr/compute/v1/projects/PROJECT_ID/regions/REGION/InstanceTemplates

{
  "name": "INSTANCE_TEMPLATE_NAME",
  "properties": {
    "machineType": "MACHINE_TYPE",
    "disks": [
      {
        "boot": true,
        "initializeParams": {
          "sourceImage": "projects/IMAGE_PROJECT/global/images/IMAGE"
        }
      }
    ],
    "networkInterfaces": [
      {
        "network": "global/networks/default"
      }
    ],
    "reservationAffinity": {
      "consumeReservationType": "NO_RESERVATION"
    }
  }
}

替换以下内容：

PROJECT_ID：要创建实例模板的项目 ID。
INSTANCE_TEMPLATE_NAME：实例模板的名称。
MACHINE_TYPE：要用于使用实例模板创建的实例的机器类型。
IMAGE_PROJECT：包含操作系统映像的映像项目；例如 debian-cloud。如需详细了解支持的映像项目，请参阅公共映像。
IMAGE：指定以下其中一项：
- 操作系统映像的特定版本；例如 debian-12-bookworm-v20240617。
- 映像系列，其格式必须为 family/IMAGE_FAMILY。此项指定最新的未弃用操作系统映像。例如，如果您指定 family/debian-12，则系统会使用 Debian 12 映像系列中的最新版本。如需详细了解如何使用映像系列，请参阅映像系列最佳实践。
