Set request timeout for services

If a service runs for too long, the system takes steps to terminate or throttle it.

For Cloud Run services, the request timeout setting specifies the time within which a response must be returned by services deployed to Cloud Run. If a response isn't returned within the time specified, the request ends and an error 504 is returned. Note that the container instance that served the request is not terminated. The container or code might keep processing the terminated request and might be processing other requests. To avoid this, prevent timeouts in your service with the following techniques:

  • Set a timeout higher than your expected execution time.
  • Track the amount of time left during execution. Then perform cleanup and return early.

Timeout period

The timeout is set by default to 5 minutes (300 seconds) and can be extended up to 60 minutes (3600 seconds).

When triggering your service from Eventarc events, Pub/Sub push subscriptions or Cloud Scheduler, the timeout of these services apply.

You can change this setting when you deploy a container image or by updating the service configuration.

In addition to changing the Cloud Run request timeout, you should also check your language framework to see whether it has its own request timeout setting that you must also update. Some clients of the Cloud Run service might also impose a more restrictive timeout.

Required roles

To get the permissions that you need to configure and deploy Cloud Run services, ask your administrator to grant you the following IAM roles:

If you are deploying a service or function from source code, you must also have additional roles granted to you on your project and Cloud Build service account.

For a list of IAM roles and permissions that are associated with Cloud Run, see Cloud Run IAM roles and Cloud Run IAM permissions. If your Cloud Run service interfaces with Google Cloud APIs, such as Cloud Client Libraries, see the service identity configuration guide. For more information about granting roles, see deployment permissions and manage access.

Setting and updating request timeout

Any configuration change leads to the creation of a new revision. Subsequent revisions will also automatically get this configuration setting unless you make explicit updates to change it.

You can set request timeout using the Google Cloud console, the gcloud command line, or a YAML file when you create a new service or deploy a new revision.

Console

  1. In the Google Cloud console, go to Cloud Run:

    Go to Cloud Run

  2. Select Services from the menu, and click Deploy container to configure a new service. If you are configuring an existing service, click the service, then click Edit and deploy new revision.

  3. If you are configuring a new service, fill out the initial service settings page, then click Container(s), Volumes, Networking, Security to expand the service configuration page.

  4. Click the Container tab.

    image

    • In the Request timeout field, enter the timeout value that you want to use in seconds. Use values ranging from 1 to 3600 seconds, or from 1 to 60 minutes.

  5. Click Create or Deploy.

gcloud

You can update the request timeout for a given revision at any time by using the following command:

gcloud run services update SERVICE --timeout=TIMEOUT

Replace the following:

  • SERVICE: the name of your service.

  • TIMEOUT: the time within which a response must be returned, using an integer value or an absolute duration value—for example 1m20s which is 1 minute, 20 seconds. If you use an integer value, the unit is assumed to be seconds. The value you specify must be less than 60 minutes.

You can also set the request timeout during deployment using the command:

gcloud run deploy --image IMAGE_URL --timeout=TIMEOUT

Replace the following:

  • IMAGE_URL: a reference to the container image, for example, us-docker.pkg.dev/cloudrun/container/hello:latest. If you use Artifact Registry, the repository REPO_NAME must already be created. The URL follows the format of LOCATION-docker.pkg.dev/PROJECT_ID/REPO_NAME/PATH:TAG .
  • TIMEOUT: the time within which a response must be returned, using an integer value or a duration value—for example, 1m20s which is 1 minute, 20 seconds. If you use an integer value, the unit is assumed to be seconds. The value you specify must be less than 60 minutes.

YAML

  1. If you are creating a new service, skip this step. If you are updating an existing service, download its YAML configuration:

    gcloud run services describe SERVICE --format export > service.yaml

  2. Update the timeoutSeconds attribute:

    apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: SERVICE
spec:
  template:
    spec:
      containers:
      - image: IMAGE
      timeoutSeconds: VALUE

    Replace the following:

    • SERVICE: the name of your Cloud Run service.
    • IMAGE_URL: a reference to the container image, for example, us-docker.pkg.dev/cloudrun/container/hello:latest. If you use Artifact Registry, the repository REPO_NAME must already be created. The URL follows the format of LOCATION-docker.pkg.dev/PROJECT_ID/REPO_NAME/PATH:TAG .
    • VALUE: the chosen timeout, in seconds.

  3. Create or update the service using the following command:

    gcloud run services replace service.yaml

Terraform

To learn how to apply or remove a Terraform configuration, see Basic Terraform commands.

Add the following to a google_cloud_run_v2_service resource in your Terraform configuration:

resource "google_cloud_run_v2_service" "default" {
  name     = "cloudrun-service-request-timeout"
  location = "us-central1"

  deletion_protection = false # set to "true" in production

  template {
    containers {
      image = "us-docker.pkg.dev/cloudrun/container/hello"
    }
    # Timeout
    timeout = "300s"
  }
}

Replace 300s with your service's desired request timeout.

View request timeout settings

To view the current request timeout settings for your Cloud Run service:

Console

  1. In the Google Cloud console, go to Cloud Run:

    Go to Cloud Run

  2. Click the service you are interested in to open the Service details page.

  3. Click the Revisions tab.

  4. In the details panel at the right, the request timeout setting is listed under the Container tab.

gcloud

  1. Use the following command:

    gcloud run services describe SERVICE

  2. Locate the request timeout setting in the returned configuration.
