Quotas and limits

This page contains usage quota and limits that apply when using Cloud Build.

Concurrency limits

Each Google Cloud project is granted quota to run ten builds at a time. When this quota is filled, requests for additional builds are queued and processed serially after the running build completes. An infinite number of builds can be queued.

From time to time, Cloud Build might allow more than ten concurrent builds per project, but users should not expect this behavior and should design their use within the quota limit of ten concurrent builds per project. Google may change this restriction at any time.

To view quota usage and limits for your projects, see Viewing all project quotas.

API rate limits

API rate limits affect the rate at which you can call the Cloud Build API. You can view and edit the rate limits using the following steps:

  1. Open the Cloud Build Quotas page.

    Go to Quotas

  2. Select the quota(s) you want to modify and click Edit quotas.

  3. Enter the new quota limit for the quota you selected.

  4. Click Submit request.


A build trigger instructs Cloud Build to automatically build your source whenever there are changes pushed to the build source. You can create up to 300 build triggers per Cloud project.
