For a new service you are creating, create the service and select Allow public accessin the Authenticationsection 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:

  
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:

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 SERVICE using:

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

Terraform

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

  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.
