This page contains usage quota and limits that apply when using Cloud Run.
The number of Cloud Run resources is limited. Quotas for Cloud Run encompass API rate limits, which affect the rate at which you can call the Cloud Run Admin API.
There is no direct limit for:
- The size of container images you can deploy.
- The number of concurrent requests served by a Cloud Run service.

1 This quota controls the maximum value that can be picked for the maximum instance attribute of a revision. However, the quota is regional: once it is granted in a given region, all revisions in that region can go up to the granted limit.
Cloud Run Admin API rate Limits
The following rate limits apply to the Cloud Run Admin API. They do not apply to the requests reaching your deployed Cloud Run services.
| Quota | Description | Limit | Increasable? | Scope |
|---|---|---|---|---|
| Cloud Run Admin API read requests | The number of API reads per 60 seconds per project. This is not the number of read requests to your Cloud Run services, which is not limited. | 1,200 per 60 seconds | Yes | Regional |
| Cloud Run Admin API write requests | The number of API writes per 60 seconds per project. This is not the number of write requests to your Cloud Run services, which is not limited. | 60 per 60 seconds | Yes | Regional |
| Job Run | Maximum number of times a job can be executed per minute per region | 3 | Yes | per region |
How to increase quota
To increase quotas above the defaults listed on this page:
Go to the Cloud Run Quotas page.
Select the quota(s) you want to modify for applicable regions and click EDIT QUOTAS.
If prompted, provide your user information, and enter the new quota limit for each quota you selected.
Your request will be routed to the support team to ensure Cloud Run can handle your use case in the selected region. You may be asked to provide details about your configuration and expected traffic patterns before the request is granted. Large increase requests may take some time to process.
