This page contains usage quota and limits that apply when using Cloud Build. Both quotas and limits can restrict the number of requests that you can send or the number of resources that you can create. Limits can also restrict a resource's attributes, such as the length of the resource's identifier.
If a quota is too low to meet your needs, you can use the Google Cloud console to request a quota increase for your project. If the Cloud console does not let you request a change for a specific quota, contact Google Cloud support.
Limits cannot be changed.
Quotas
Cloud Build enforces quotas on running builds for various reasons. For example, quotas help to protect the community of Google Cloud users by preventing unforeseen spikes in usage. Google Cloud also offers free trial quotas that provide limited access for projects to help you explore Google Cloud on a free trial basis.
By default, the following Cloud Build quotas apply to each Google Cloud project. However, per-project quotas depend on usage and may vary over time.
| Resource | Description | Default limit | Can be increased | Scope |
|---|---|---|---|---|
| Private pool | Number of private pools | 2 - 10 | Yes | Per region |
| Build triggers | Number of build triggers | 300 | Yes | Per region |
| CPU | Number of concurrent CPUs
run in a regional private pool |
0 * - 2400 | Yes. When this quota is filled, requests for additional CPUs are queued and processed serially. | Per region |
| CPU | Number of concurrent CPUs
run in a regional default pool |
5 - 100 | No. If you require more than 100 concurrent CPUs, use private pools. | Per region |
| Request | Number of concurrent builds run in a global default pool |
10 - 30 | No. If you want to run more than 30 concurrent builds, consider using private pools. |
Global |
* Depending on your project and usage, you may not have quotas to use private pools. If this is the case, you can use default pools.
Region restrictions for some projects
Depending on the usage, certain projects may be restricted to only use Cloud Build in certain regions. For more information see Locations.
