删除虚拟机

本文档介绍如何删除虚拟机 (VM) 实例。

如果您不再需要虚拟机，可将其删除，以免虚拟机及其挂接的资源产生费用。如果要保留挂接的资源，请在删除虚拟机之前执行以下一项或多项操作：

如需保留挂接到要删除的 N1 虚拟机的 GPU，请从虚拟机中移除 GPU。
如需保留永久性磁盘，请执行以下操作之一：
- 如需保留启动磁盘，请将启动磁盘与虚拟机分离。
- 如需保留启动磁盘或非启动磁盘，请将磁盘的自动删除设置设置为 false。
为虚拟机取消分配静态外部 IP 地址。

准备工作

设置身份验证（如果尚未设置）。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，您可以按如下方式向 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

如需获得删除虚拟机所需的权限，请让管理员向您授予项目的 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删除虚拟机所需的权限。如需查看所需的确切权限，请展开所需权限部分：

所需权限

您需要具备以下权限才能删除虚拟机：

针对虚拟机的 compute.instances.delete 权限
如需强制删除挂接的永久性磁盘：针对磁盘的 compute.disks.delete 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。

结算影响

删除虚拟机后，除非符合以下任何情况，否则 Google Cloud 将不再针对虚拟机及其挂接的资源向您收取费用：

如果您删除在单租户节点上托管的虚拟机，则您将继续为单租户节点本身支付费用，而不是为在该节点上托管的各个虚拟机支付费用。
如果您有承诺使用折扣，则无论您是否使用这些资源，您都需要继续为所承诺的资源付费。
如果您保留了挂接到虚拟机的任何资源，这些资源会继续产生费用，直到您将其删除。例如，如果您删除一个虚拟机，但保留了挂接到该虚拟机的永久性磁盘卷，则这些磁盘会继续产生费用。

如需了解详情，请参阅虚拟机实例价格。

删除虚拟机的过程

删除虚拟机时，Compute Engine 会执行以下操作：

Compute Engine 会向虚拟机发送 ACPI 关停信号，然后在几秒钟内将虚拟机状态设置为 STOPPING。
Compute Engine 会在虚拟机中启动操作系统 (OS) 的正常关停。根据虚拟机类型，关停期如下所示：
- 抢占式虚拟机：抢占式虚拟机的关停期为 30 秒，与抢占过程的时长相同。
- 其他虚拟机类型：任何其他虚拟机类型的关停期至少为 90 秒。
关停期结束时，Compute Engine 将永久删除虚拟机及其挂接的资源。如果您将永久性磁盘配置为在删除其挂接到的虚拟机时保留，则 Compute Engine 会在删除虚拟机时保留该磁盘。

删除虚拟机

如需删除一个或多个虚拟机，请参阅本文档中的以下部分之一：

如需删除虚拟机及其所有挂接的资源（默认），请参阅删除虚拟机和所有挂接的资源。
如需删除虚拟机但保留其挂接的永久性磁盘卷，请参阅删除虚拟机并保留永久性磁盘卷。

删除虚拟机和所有挂接的资源

删除一个虚拟机时，默认情况下，Compute Engine 会删除该虚拟机及其所有挂接的资源。但是，如果您将永久性磁盘配置为在删除虚拟机时保留，则可以使用 gcloud CLI 覆盖此设置并同时删除虚拟机和磁盘。

如需同时删除多个虚拟机，请使用 Google Cloud 控制台或 gcloud CLI（对于位于同一可用区的虚拟机）。否则，如需删除单个虚拟机，请使用本部分中介绍的任何方法。

控制台

如需删除一个或多个虚拟机，请执行以下操作：

在 Google Cloud 控制台中，转到虚拟机实例页面。

转到虚拟机实例
选择要删除的虚拟机。
点击删除，然后再次点击删除进行确认。

gcloud

如需删除一个或多个虚拟机，请使用 gcloud compute instances delete 命令。

gcloud compute instances delete VM_NAMES \
    --zone=ZONE

替换以下内容：

VM_NAMES：位于同一可用区的虚拟机名称列表（以空格分隔）；例如 vm-01 vm-02 vm-03。
ZONE：虚拟机的可用区。

（可选）如需强制删除挂接到一个或多个虚拟机的永久性磁盘卷，请添加 --delete-disks 标志。

gcloud compute instances delete VM_NAMES \
    --delete-disks=DELETE_DISK_TYPE \
    --zone=ZONE

将 DELETE_DISK_TYPE 替换为要删除的所挂接永久性磁盘卷的类型。请指定以下某个值：

如需删除所有类型的磁盘：all。
如需仅删除启动磁盘：boot。
如需仅删除非启动磁盘：data。

REST

如需删除虚拟机，请向 instances delete 方法发出 DELETE 请求。

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

替换以下内容：

PROJECT_ID：虚拟机所在项目的 ID。
ZONE：虚拟机的可用区。
VM_NAME：虚拟机名称。

删除虚拟机并保留永久性磁盘卷

默认情况下，删除虚拟机会删除虚拟机及其挂接的资源。但是，使用 gcloud CLI 删除虚拟机时，您可以指定保留挂接的启动磁盘和/或非启动磁盘，而不考虑磁盘的自动删除设置。

如需删除位于同一可用区的一个或多个虚拟机，同时保留其挂接的永久性磁盘卷，请使用带有 --keep-disks 标志的 gcloud compute instances delete 命令。

gcloud compute instances delete VM_NAMES \
    --keep-disks=KEEP_DISK_TYPE \
    --zone=ZONE

替换以下内容：

VM_NAMES：位于同一可用区的虚拟机名称列表（以空格分隔）；例如 vm-01 vm-02 vm-03。
KEEP_DISK_TYPE：要保留的所挂接永久性磁盘卷的类型。请指定以下某个值：
- 如需保留所有类型的磁盘：all。
- 如需仅保留启动磁盘：boot。
- 如需仅保留非启动磁盘：data。
ZONE：虚拟机所在的可用区。
