本文档介绍如何查看现有虚拟机 (VM) 实例的详细信息。
查看虚拟机的详细信息有助于查看其配置和状态,例如挂接的磁盘、创建时间戳、机器类型和虚拟机 ID(可用于使用不可变值引用虚拟机)。
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:
When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
-
Install the Google Cloud CLI, then initialize it by running the following command:
gcloud init
- Set a default region and zone.
REST
如需在本地开发环境中使用本页面上的 REST API 示例,请使用您提供给 gcloud CLI 的凭据。
Install the Google Cloud CLI, then initialize it by running the following command:
gcloud init
如需了解详情,请参阅 Google Cloud 身份验证文档中的使用 REST 时进行身份验证。
-
所需的角色
如需获得查看虚拟机详细信息所需的权限,请让管理员向您授予虚拟机或项目的 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查看虚拟机的详细信息所需的 compute.instances.get
权限。
查看虚拟机的详细信息
如需查看虚拟机的详细信息,请选择以下选项之一:
如需查看虚拟机的详细信息,请使用 gcloud compute instances describe
命令。
gcloud compute instances describe VM_NAME \
--zone=ZONE
请替换以下内容:
VM_NAME
:虚拟机名称。ZONE
:该虚拟机所在的可用区。

确定实例的 CPU 和内存分配
可以根据计算实例使用的机器类型确定分配给计算实例的 CPU 数量和内存量,例如:
c3-standard-22
:C3 是机器系列名称,standard
是实例的内存分配类型,22
是分配给实例的 vCPU 数量。通常,standard
机器类型使用每个 vCPU 4 GB 内存的比率。因此,此机器类型会配备 88 GB 的 RAM。standard
、highmem
、highcpu
、ultamem
和megamem
机器类型的内存与 CPU 比率因机器系列而略有不同,因此请参阅机器系列页面,以确定为每种机器类型分配的确切内存量。n2-custom-8-16384
:对于自定义机器类型,机器类型的第一部分是机器系列,但 N1 机器类型除外,该机器类型根本不包含机器系列。custom
后面的第一个数字是 vCPU 数量,最后一个数字是分配给实例的内存量(以 MB 为单位)。
如需详细了解机器类型,请参阅机器家族资源和比较指南。
