本文档列出了适用于 Cloud Domains 的配额和系统限制。
- 配额具有默认值，但您通常可以申请调整。
- 系统限制是无法更改的固定值。
如需更改配额，请参阅申请额外的配额。
Google Cloud 使用配额来帮助确保公平性并减少资源使用和可用性的激增。配额用于限制您的 Google Cloud 项目可使用多少Google Cloud 资源。配额适用于一系列资源类型，包括硬件、软件和网络组件。例如，配额可以限制对某项服务的 API 调用次数、您的项目并发使用的负载均衡器数量或者您可以创建的项目数量。配额可以防止服务过载，从而保护Google Cloud 用户社区。配额还可以帮助您管理自己的 Google Cloud 资源。
Cloud 配额系统执行以下操作：
在大多数情况下，当您尝试消耗的资源超出其配额允许的范围时，系统会阻止对资源的访问，并且您尝试执行的任务会失败。
配额通常在 Google Cloud 项目级别应用。您在一个项目中使用资源不会影响您在另一个项目中的可用配额。在 Google Cloud 项目中，配额在所有应用和 IP 地址间共享。
如需了解详情，请参阅 Cloud 配额概览。
Cloud Domains 资源也有系统限制。系统限制不能更改。
权限
如需查看配额或申请增加配额，Identity and Access Management (IAM) 主账号需要具备以下某个 Cloud Domains 角色：
| 任务 | 所需角色 |
|---|---|
| 检查项目的配额 | Cloud Domains Viewer (roles/domains.viewer) |
| 修改配额，申请更多配额 | Cloud Domains Admin (roles/domains.admin) |
配额
如需查看现有配额和用量并申请增加配额，请在Google Cloud 控制台中前往配额页面。
Cloud Domains 的配额如下：
- 域名注册数量
- 每天除只读调用以外的 API 请求数
- 每分钟 API 请求数
- 每天敏感 API 请求数
- 每分钟敏感 API 请求数
敏感 API 请求包括对 RetrieveRegisterParameters 和 RegisterDomain 方法的调用。
Manage quotas
Cloud Domains enforces quotas on resource usage for various reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Quotas also help users who are exploring Google Cloud with the free tier to stay within their trial.
All projects start with the same quotas, which you can change by requesting additional quota. Some quotas might increase automatically based on your use of a product.
Permissions
To view quotas or request quota increases, Identity and Access Management (IAM) principals need one of the following roles.
| Task | Required role |
|---|---|
| Check quotas for a project | One of the following:
|
| Modify quotas, request additional quota | One of the following:
|
Check your quota
Console
- In the Google Cloud console, go to the Quotas page.
- To search for the quota that you want to update, use the Filter table. If you don't know the name of the quota, use the links on this page instead.
gcloud
Using the Google Cloud CLI, run the following command to
check your quotas. Replace PROJECT_ID with your own project ID.
gcloud compute project-info describe --project PROJECT_IDTo check your used quota in a region, run the following command:
gcloud compute regions describe example-region
Errors when exceeding your quota
If you exceed a quota with a gcloud command,
gcloud outputs a quota exceeded error
message and returns with the exit code 1.
If you exceed a quota with an API request, Google Cloud returns the
following HTTP status code: 413 Request Entity Too Large.
Request additional quota
To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.
Resource availability
Each quota represents a maximum number for a particular type of resource that you can create, if that resource is available. It's important to note that quotas don't guarantee resource availability. Even if you have available quota, you can't create a new resource if it is not available.
For example, you might have sufficient quota to create a new regional, external IP address in a given region. However, that is not possible if there are no available external IP addresses in that region. Zonal resource availability can also affect your ability to create a new resource.
Situations where resources are unavailable in an entire region are rare. However, resources within a zone can be depleted from time to time, typically without impact to the service level agreement (SLA) for the type of resource. For more information, review the relevant SLA for the resource.
