@Marvin Now I have prefect worker whose type is cloud_run, the worker is running as GCP Cloud Run service. When I run a deployment, the worker create cloud run job. Can I configure which docker image the worker use to create cloud run job?

Yes! You can configure the Docker image that the Cloud Run worker uses to create Cloud Run jobs. There are two main ways to do this: 1. Through the Work Pool Configuration: When creating or updating a Cloud Run work pool, you can specify the default image in the base job template. This will be used for all jobs unless overridden at the deployment level. 2. Through the Deployment Configuration: You can specify the image for specific deployments, which will override the work pool default. Here's how to do both: ### Option 1: Setting the image in the Work Pool When creating a Cloud Run work pool, you can specify the image in the base job template. Here's an example:
Copy code
python
{
    "image": "your-docker-image:tag",
    "cpu": 1,
    "memory": 512,
    "memory_unit": "Mi",
    "region": "us-central1"
}
You can set this either through the Prefect UI or using the CLI:
Copy code
bash
prefect work-pool create "my-cloud-run-pool" \
    --type cloud-run \
    --base-job-template path/to/template.json
### Option 2: Setting the image in the Deployment When creating a deployment, you can specify the image in the deployment configuration:
Copy code
python
from prefect import flow
from prefect.deployments import Deployment

@flow
def my_flow():
    # your flow code here
    pass

deployment = Deployment.build_from_flow(
    flow=my_flow,
    name="my-deployment",
    work_pool_name="my-cloud-run-pool",
    job_variables={
        "image": "your-docker-image:tag"
    }
)
Or when using the modern deployment syntax in Prefect 3.x:
Copy code
python
@flow
def my_flow():
    # your flow code here
    pass

if __name__ == "__main__":
    my_flow.deploy(
        name="my-deployment",
        work_pool_name="my-cloud-run-pool",
        job_variables={
            "image": "your-docker-image:tag"
        }
    )
Important notes: 1. The image must be accessible to your GCP Cloud Run service 2. If you're using a private container registry, make sure your Cloud Run service has the necessary permissions to pull the image 3. The image should contain all the dependencies required by your flow 4. Make sure the image has Python and the required Prefect version installed Would you like me to provide more specific details about any of these configuration options or help with setting up a particular approach?

To resolve this, please: 1. Verify Service Account: - Check which service account is being used in your GCP Credentials block - Ensure this service account exists and is active 2. Verify Permissions: - Go to the Google Cloud Console → IAM & Admin → IAM - Find your service account - Verify it has the necessary roles mentioned above - If using Workload Identity, ensure the federation is set up correctly 3. Check Region Configuration: - The error shows you're trying to use
asia-northeast3
- Make sure your service account has permissions in this region - Verify the region matches what's configured in your work pool Would you like me to help you verify any specific part of this setup? Please let me know: 1. Which service account you're using 2. Whether you're using Workload Identity 3. The specific GCP project ID This will help me provide more targeted assistance.

@Marvin But the service account has
roles/run.admin

I see the 403 permission error for Cloud Run. Let me help you troubleshoot this systematically. Since your Cloud Run worker is running as a Cloud Run service itself, this is likely an issue with the service account that the Cloud Run service (worker) is using. Here's what we need to check: 1. First, verify the service account being used by your Cloud Run worker service:
Copy code
bash
   gcloud run services describe YOUR_WORKER_SERVICE_NAME \
     --region asia-northeast3 \
     --format="get(serviceConfig.serviceAccountEmail)"
2. This service account needs the following permissions: -
roles/run.developer
- to create and manage Cloud Run jobs -
roles/run.invoker
- to invoke Cloud Run services -
roles/iam.serviceAccountUser
- to act as the service account You can grant these permissions using:
Copy code
bash
# Replace YOUR_PROJECT_ID and SERVICE_ACCOUNT_EMAIL with actual values
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
    --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
    --role="roles/run.developer"

gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
    --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
    --role="roles/run.invoker"

gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
    --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
    --role="roles/iam.serviceAccountUser"
3. Additionally, check if the Cloud Run API is enabled:
Copy code
bash
gcloud services enable <http://run.googleapis.com|run.googleapis.com>
4. Verify region permissions: - The error shows you're using
asia-northeast3
- Make sure your service account has permissions in this region - Confirm this matches your work pool configuration To help you further, could you please: 1. Confirm if you're using the default compute service account (
<mailto:PROJECT_NUMBER-compute@developer.gserviceaccount.com|PROJECT_NUMBER-compute@developer.gserviceaccount.com>
) or a custom service account? 2. Can you check if the Cloud Run API is enabled in your project? 3. Are you able to create Cloud Run jobs manually in the GCP Console with the same service account? This will help me provide more specific guidance for your setup. Also, as a temporary test, you could try granting the more permissive
roles/run.admin
role to verify if it's purely a permissions issue:
Copy code
bash
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
    --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
    --role="roles/run.admin"
Note: While this would work for testing, it's recommended to use the more granular permissions mentioned above for production use.

@Marvin I defined the worker Cloud Run as below by terraform:
Copy code
resource "google_cloud_run_v2_service" "prefect_worker" {
  project             = var.project
  name                = "prefect-worker"
  location            = var.location
  deletion_protection = false

  depends_on           = [google_cloud_run_v2_service.prefect_server]

  template {
    scaling {
      max_instance_count = 1
      min_instance_count = 1
    }
    containers {
      image   = local.prefect_server_image
      command = ["/bin/sh", "-c"]
      args = [
        <<-EOT
          prefect worker start --install-policy always --with-healthcheck -p cloud_run_work_pool -t cloud-run
        EOT
      ]
      env {
        name  = "PREFECT_API_URL"
        value = local.prefect_api_url
      }
      service_account = var.prefect_server_service_account_email
And the prefect server service account has roles below: • Cloud Run Admin • Cloud SQL Client • IAP-secured Web App User • Service Account User And the worker still fail to create job.

I notice that while the service account has
Cloud Run Admin
and
Service Account User
roles, there might be a specific requirement for Cloud Run job creation. Let's modify the service account permissions to ensure it has all necessary permissions. Given your Terraform configuration, the service account needs additional permissions to create and manage Cloud Run jobs. Here's what you should add to your service account: 1. Add IAM permissions for job creation. You can add this to your Terraform configuration:
Copy code
hcl
resource "google_project_iam_member" "prefect_server_cloudrun_jobs" {
  project = var.project
  role    = "roles/run.developer"
  member  = "serviceAccount:${var.prefect_server_service_account_email}"
}

# If not already present, add this for job invocation
resource "google_project_iam_member" "prefect_server_cloudrun_invoker" {
  project = var.project
  role    = "roles/run.invoker"
  member  = "serviceAccount:${var.prefect_server_service_account_email}"
}
2. Verify the service account has permission to create other service accounts (needed for job execution):
Copy code
hcl
resource "google_project_iam_member" "prefect_server_sa_creator" {
  project = var.project
  role    = "roles/iam.serviceAccountCreator"
  member  = "serviceAccount:${var.prefect_server_service_account_email}"
}
3. Add permission to act as service accounts:
Copy code
hcl
resource "google_project_iam_member" "prefect_server_sa_user" {
  project = var.project
  role    = "roles/iam.serviceAccountUser"
  member  = "serviceAccount:${var.prefect_server_service_account_email}"
}
4. Additionally, make sure your Cloud Run service has the necessary security context:
Copy code
hcl
resource "google_cloud_run_v2_service" "prefect_worker" {
  # ... your existing configuration ...

  template {
    containers {
      # ... your existing container configuration ...

      # Add this if not present
      service_account = var.prefect_server_service_account_email
    }
  }
}
5. Enable the necessary APIs if not already enabled:
Copy code
hcl
resource "google_project_service" "required_apis" {
  for_each = toset([
    "<http://run.googleapis.com|run.googleapis.com>",
    "<http://iam.googleapis.com|iam.googleapis.com>",
    "<http://cloudresourcemanager.googleapis.com|cloudresourcemanager.googleapis.com>"
  ])
  
  project = var.project
  service = each.value

  disable_on_destroy = false
}
After applying these changes: 1. Apply the Terraform changes 2. Restart your Cloud Run worker service 3. Try running a deployment again If you're still seeing issues, could you please: 1. Check the Cloud Run service logs for any additional error messages 2. Verify if the service account has the correct project-level permissions by running:
Copy code
bash
gcloud projects get-iam-policy YOUR_PROJECT_ID \
    --flatten="bindings[].members" \
    --format='table(bindings.role)' \
    --filter="bindings.members:${var.prefect_server_service_account_email}"
This will show all roles assigned to your service account at the project level. Would you like me to provide any additional details about any of these configurations or help troubleshoot further if these changes don't resolve the issue?
u
@Marvin why the service account need serviceAccountCreator role?
m
thought for 42.9 seconds
I apologize for my previous response where I incorrectly included the
roles/iam.serviceAccountCreator
role. After researching further, I can confirm that this role is not required for the Cloud Run worker to function properly. For a Cloud Run worker to create and manage Cloud Run jobs, you only need these essential roles: 1.
roles/run.developer
- to create and manage Cloud Run jobs 2.
roles/run.invoker
- to invoke Cloud Run services 3.
roles/iam.serviceAccountUser
- to act as the service account Your current service account already has sufficient permissions with: - Cloud Run Admin (which is actually more permissive than needed) - Service Account User - Cloud SQL Client (for database access) - IAP-secured Web App User The
serviceAccountCreator
role is not necessary because: 1. The Cloud Run worker doesn't need to create new service accounts 2. It only needs to execute Cloud Run jobs using the existing service account Would you like me to provide a more minimal set of IAM permissions that would work for your use case? This could help improve security by following the principle of least privilege.

Based on the error and the Cloud Run V2 API requirements, here's how to fix this issue. You need to provide a proper job template in your work pool configuration. Here's the correct template structure for Cloud Run V2:
Copy code
json
{
    "job": {
        "template": {
            "template": {
                "containers": [
                    {
                        "image": "${image}",
                        "resources": {
                            "cpu_limit": "1",
                            "memory_limit": "512Mi"
                        },
                        "env": [
                            {
                                "name": "PREFECT_API_URL",
                                "value": "${prefect_api_url}"
                            },
                            {
                                "name": "PREFECT_API_KEY",
                                "value": "${prefect_api_key}"
                            }
                        ]
                    }
                ],
                "serviceAccount": "${service_account_name}",

        }
    }
}
You can update your work pool in one of two ways: 1. Using the UI: - Go to your work pool settings - Click "Edit" - In the "Base Job Template" section, paste the above JSON - Update the values as needed 2. Using the CLI:
Copy code
bash
# First save the template to a file named template.json
prefect work-pool create "your-pool-name" \
    --type cloud-run-v2 \
    --base-job-template template.json
Key points about the template: 1. Note the nested
template
structure - this is required for Cloud Run V2 2. The outer
job
wrapper is required 3. Variables in
${...}
will be replaced with actual values at runtime 4. Make sure to set appropriate resource limits for your needs Variables you can use in the template: - `${image}`: Docker image to use - `${prefect_api_url}`: Your Prefect API URL - `${prefect_api_key}`: API key if needed - `${service_account_name}`: The service account email Would you like me to: 1. Provide a more detailed template with additional configuration options? 2. Help you troubleshoot the specific values in your current configuration? 3. Show how to verify the configuration is correct before deploying?

Based on the research and the Cloud Run V2 API requirements, here's the correct template structure. The key difference is in how the template is structured for V2:
Copy code
json
{
    "template": {
        "containers": [
            {
                "image": "${image}",
                "resources": {
                    "limits": {
                        "cpu": "1",
                        "memory": "512Mi"
                    }
                },
                "env": [
                    {
                        "name": "PREFECT_API_URL",
                        "value": "${prefect_api_url}"
                    },
                    {
                        "name": "PREFECT_API_KEY",
                        "value": "${prefect_api_key}"
                    }
                ]
            }
        ],
        "serviceAccount": "${service_account_name}",
        "timeoutSeconds": 600
    }
}
Key differences in this V2 template: 1. The structure is flatter - no nested
job
wrapper 2. Resources are specified under
limits
3. The template is directly at the root level You can update your work pool using one of these methods: 1. Using the UI: - Go to your work pool settings - Click "Edit" - Replace the entire base job template with the above JSON - Save the changes 2. Using the CLI:
Copy code
bash
# Save the template to a file
echo '{
    "template": {
        "containers": [
            {
                "image": "${image}",

                    "limits": {
                        "cpu": "1",
                        "memory": "512Mi"
                    }
                },
                "env": [
                    {
                        "name": "PREFECT_API_URL",

@Marvin I've solve the problems, but the worker still says Credentials are missing, when creating job.

For a Cloud Run V2 worker, you need to configure credentials in two places: 1. Work Pool Configuration: You need to specify a GCP Credentials block in your work pool settings. Here's how to set it up: a. First, create a GCP Credentials block if you haven't already:
Copy code
bash
   prefect block register -m prefect_gcp
b. Then create the credentials block either through the UI or Python:
Copy code
python
   from prefect_gcp import GcpCredentials
   
   credentials = GcpCredentials(
       service_account_info=None,  # Leave as None when running on GCP
       service_account_file=None,  # Leave as None when running on GCP
       project="your-project-id"   # Your GCP project ID
   )
   credentials.save("gcp-credentials-block-name")
2. Worker Service Account: Since your worker is running as a Cloud Run service, it should use the default compute service account or a custom service account. This service account needs:
Copy code
bash
   # Check the current service account being used by your worker
   gcloud run services describe prefect-worker \
     --region YOUR_REGION \
     --format="get(serviceConfig.serviceAccountEmail)"
Ensure this service account has these roles:
Copy code
bash
   # Replace SERVICE_ACCOUNT_EMAIL with the email from above command
   gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
     --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
     --role="roles/run.developer"

   gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
     --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
     --role="roles/run.invoker"

   gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
     --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \
     --role="roles/iam.serviceAccountUser"
3. Update Work Pool Configuration: Make sure your work pool has the credentials block configured. In the work pool settings, you should see a field for GCP Credentials. Make sure it's set to your credentials block. You can also update it via CLI:
Copy code
bash
   prefect work-pool update "your-pool-name" \
     --set variables='{"credentials": "gcp-credentials-block-name"}'
To troubleshoot: 1. Check Worker Logs:
Copy code
bash
   gcloud run services logs read prefect-worker --region YOUR_REGION
Look for more detailed error messages about the credentials issue. 2. Verify Work Pool Configuration:
Copy code
bash
   prefect work-pool inspect "your-pool-name"
Check that the credentials block is properly referenced. 3. Test Service Account Permissions:
Copy code
bash
   # Get the service account currently being used
   SA_EMAIL=$(gcloud run services describe prefect-worker \
     --region YOUR_REGION \
     --format="get(serviceConfig.serviceAccountEmail)")
   
   # List its roles
   gcloud projects get-iam-policy YOUR_PROJECT_ID \
     --flatten="bindings[].members" \
     --format='table(bindings.role)' \
     --filter="bindings.members:$SA_EMAIL"
Could you please: 1. Check if you see the credentials block properly configured in your work pool settings? 2. Share any specific error message you're seeing about the missing credentials? 3. Confirm whether you're using a custom service account or the default compute service account? This will help me provide more targeted assistance for your setup.
