There are two ways to create a public Cloud Run service:

- [Disable](https://docs.cloud.google.com/run/docs/authenticating/public#invoker_check) the Cloud Run Invoker IAM check (recommended).
- [Assign](https://docs.cloud.google.com/run/docs/authenticating/public#assign-allusers-iam-invoker) the Cloud Run Invoker IAM role to the `allUsers` member type.

### Required roles

To disable or re-enable the Invoker IAM check on a service, you
must have the following permissions:

- `run.services.create`
- `run.services.update`
- `run.services.setIamPolicy`

These permissions are included in the
[Cloud Run Admin](https://docs.cloud.google.com/iam/docs/roles-permissions/run#run.admin)
(`roles/run.admin`) role. See
[Cloud Run IAM roles](https://docs.cloud.google.com/run/docs/reference/iam/roles)
for the full list of roles and their associated permissions.

#### Disable the Cloud Run Invoker IAM check

The recommended way to make a public service is to disable the
Cloud Run Invoker IAM check.
Cloud Run enforces this check by default. Use this solution when
the project is subject to the
[domain restricted sharing constraint in an organization policy](https://docs.cloud.google.com/resource-manager/docs/organization-policy/restricting-domains).

To disable the check:

### Console

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

   [Go to Cloud Run](https://console.cloud.google.com/run)
2. Select **Services** from the Cloud Run navigation menu:

   1. If you are configuring a new service, click **Deploy container** and
      fill out the initial service settings page.

   2. If you are configuring an existing service, click the service, then
      click the **Security** tab.

3. Select **Allow public access**.

   > [!NOTE]
   > **Note:** Enabling the Cloud Run Invoker IAM check in the Google Cloud console removes any existing `roles/run.invoker` role bindings for the `allUsers` principal type. If you later re-enable the check, you must manually re-grant the role to restore public access.

4. Click **Create** for a new service. Click **View diff \& redeploy** , then **Deploy changes** for an existing service.

### gcloud

- For a new service, use the `gcloud run deploy` command with the
  `--no-invoker-iam-check` flag:

  ```bash
  gcloud run deploy SERVICE_NAME --no-invoker-iam-check
  ```

  Replace `SERVICE_NAME` with the service name.
- For an existing service, use the `gcloud run services update` command with
  the `--no-invoker-iam-check` flag:

  ```bash
  gcloud run services update SERVICE_NAME --no-invoker-iam-check
  ```

Replace `SERVICE_NAME` with the service name.

### YAML

1. To view and download the configuration:

   ```bash
   gcloud run services describe SERVICE --format export > service.yaml
   ```
2. Update the `run.googleapis.com/invoker-iam-disabled:` annotation:

   ```yaml
   apiVersion: serving.knative.dev/v1
   kind: Service
   metadata:
       annotations:
         run.googleapis.com/invoker-iam-disabled: 'true'
       name: SERVICE_NAME
   ```

   Replace <var translate="no">SERVICE_NAME</var> with the name of your Cloud Run
   service.
3. Replace the service with its new configuration using the following command:

   ```bash
   gcloud run services replace service.yaml
   ```

### Terraform

To learn how to apply or remove a Terraform configuration, see
[Basic Terraform commands](https://docs.cloud.google.com/docs/terraform/basic-commands).
Add the following to a [`google_cloud_run_v2_service`](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/cloud_run_v2_service) resource in your Terraform configuration:  

    resource "google_cloud_run_v2_service" "default" {
       name     = "SERVICE"
       location = "REGION"
       invoker_iam_disabled = true

       template {
          containers {
          image = "IMAGE_URL"
          }
       }
    }

Replace the following:

- <var translate="no">SERVICE</var>: the name of your Cloud Run service.
- <var translate="no">REGION</var>: the Google Cloud region---for example, `europe-west1`.
- `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](https://docs.cloud.google.com/artifact-registry/docs/repositories/create-repos#docker) <var translate="no">REPO_NAME</var> must already be created. The URL follows the format of `LOCATION-docker.pkg.dev/PROJECT_ID/REPO_NAME/PATH:TAG`

Verify that the check is disabled after deployment by navigating to the
service's HTTPS endpoint.

#### Re-enable the Cloud Run Invoker IAM check

To re-enable the check:

### Console

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

   [Go to Cloud Run](https://console.cloud.google.com/run/services)
2. Click the service, then click the **Security** tab.

3. Select **Require authentication** and select **Identity and Access Management (IAM)**.

4. Click **View diff \& redeploy** , then click **Deploy changes**.

### gcloud

- Update the service by passing the `--invoker-iam-check` flag:

  ```bash
  gcloud run services update SERVICE_NAME --invoker-iam-check
  ```

  Replace `SERVICE_NAME` with the service name.

### YAML

1. To view and download the configuration:

   ```bash
   gcloud run services describe SERVICE --format export > service.yaml
   ```
2. Update the `run.googleapis.com/invoker-iam-disabled:` annotation:

   <br />

   ```yaml
   apiVersion: serving.knative.dev/v1
    kind: Service
    metadata:
       annotations:
          run.googleapis.com/invoker-iam-disabled: 'false'
       name: SERVICE_NAME
   ```

   <br />

   Replace `SERVICE_NAME` with the name of your
   Cloud Run service.

### Terraform

To learn how to apply or remove a Terraform configuration, see
[Basic Terraform commands](https://docs.cloud.google.com/docs/terraform/basic-commands).
Add the following to a [`google_cloud_run_v2_service`](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/cloud_run_v2_service) resource in your Terraform configuration:  

    resource "google_cloud_run_v2_service" "default" {
       name     = "SERVICE"
       location = "REGION"
       invoker_iam_disabled = false

       template {
          containers {
          image = "IMAGE_URL"
          }
       }
    }

Replace the following:

- <var translate="no">SERVICE</var>: the name of your Cloud Run service.
- <var translate="no">REGION</var>: the Google Cloud region---for example, `europe-west1`.
- `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](https://docs.cloud.google.com/artifact-registry/docs/repositories/create-repos#docker) <var translate="no">REPO_NAME</var> must already be created. The URL follows the format of `LOCATION-docker.pkg.dev/PROJECT_ID/REPO_NAME/PATH:TAG`

Verify that the check is re-enabled after deployment by navigating to the
service's HTTPS endpoint.

### Configure organization policy for the Cloud Run invoker IAM check

> [!NOTE]
> **Note:** If you participated in the invitation-only access to this feature, you might have an additional constraint (`constraints/run.requireInvokerIam`) that also controls access to the check.

If you're an administrator, you can restrict the ability to
[disable the Invoker IAM check](https://docs.cloud.google.com/run/docs/authenticating/public#invoker_check)
by using the `constraints/run.managed.requireInvokerIam` managed constraint.
This constraint is not enforced by default.

### Assign the Cloud Run IAM Invoker role to the `allUsers` member type

> [!IMPORTANT]
> **Important:** These instructions won't succeed if your project is under a [domain restricted sharing organization policy](https://docs.cloud.google.com/resource-manager/docs/organization-policy/restricting-domains) that restricts granting IAM roles to the `allUsers` member type as described in this page. If that is the case, you should [disable the Cloud RunIAM Invoker IAM check](https://docs.cloud.google.com/run/docs/authenticating/public#disable_invoker) instead.

You can allow public access to a service by assigning the
Cloud Run Invoker IAM role to the `allUsers` member type.

You must have the `run.services.setIamPolicy` permission to configure authentication
on a Cloud Run service. This permission is included in the
Cloud Run Admin role. See
[Cloud Run IAM roles](https://docs.cloud.google.com/run/docs/reference/iam/roles)
for the full list of roles and their associated permissions.

### Console

For an existing Cloud Run service:

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

   [Go to Google Cloud console](https://console.cloud.google.com/run/services)
2. To the left of the service that you want to make public, click the
   checkbox. Don't click the service itself.

3. In the information pane in the top-right corner, click the
   **Permissions** tab. If the information pane isn't visible, you might
   need to click **Show Info Panel** , then click **Permissions**.

4. Click **Add principal**.

In the **New principals** field, enter the value `allUsers`.

1. From the **Select a role** menu, select the
   **Cloud Run Invoker** role.

2. Click **Save**.

3. You will be prompted to verify that you would like to make this resource
   public. Click **Allow public access** to apply the change to the service
   IAM settings.

For a new service you are creating, [create the service](https://docs.cloud.google.com/run/docs/deploying#service)
and select **Allow public access** in the **Authentication** section
to make the service publicly available. To make a service private, select
**Require authentication**.

### gcloud

To make a service publicly accessible, use the `gcloud run services` command
to add the special `allUsers` member type to a service and grant it the
`roles/run.invoker` role:

```bash
  gcloud run services add-iam-policy-binding [SERVICE_NAME] \
    --member="allUsers" \
    --role="roles/run.invoker"
```

Run the `gcloud run deploy` command to make your service
publicly accessible when you deploy your service:

```bash
gcloud run deploy [SERVICE_NAME] ... --allow-unauthenticated
```

### YAML

Create a file named `policy.yaml` with the following content:

    bindings:
    - members:
      - allUsers
      role: roles/run.invoker

Allow public access for the existing <var translate="no">SERVICE</var> using:

```bash
gcloud run services set-iam-policy SERVICE policy.yaml
```

### Terraform

To learn how to apply or remove a Terraform configuration, see
[Basic Terraform commands](https://docs.cloud.google.com/docs/terraform/basic-commands).
Add the following to a [`google_cloud_run_v2_service`](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/cloud_run_v2_service) resource in your Terraform configuration:  

    resource "google_cloud_run_v2_service" "default" {
      name     = "public-service"
      location = "us-central1"

      deletion_protection = false # set to "true" in production

      template {
        containers {
          image = "us-docker.pkg.dev/cloudrun/container/hello"
        }
      }
    }

To update the service IAM binding for `roles/run.invoker`, add
the following resource referencing your Cloud Run service:

    resource "google_cloud_run_service_iam_binding" "default" {
      location = google_cloud_run_v2_service.default.location
      service  = google_cloud_run_v2_service.default.name
      role     = "roles/run.invoker"
      members = [
        "allUsers"
      ]
    }

This binding is only authoritative for the given role. Other IAM
bindings within the service IAM policy are preserved.
