prefect_gcp.workers.cloud_run

Module containing the Cloud Run worker used for executing flow runs as Cloud Run jobs.

Get started by creating a Cloud Run work pool:

prefect work-pool create 'my-cloud-run-pool' --type cloud-run

Then start a Cloud Run worker with the following command:

prefect worker start --pool 'my-cloud-run-pool'

Configuration

Advanced Configuration

Using a custom Cloud Run job template

Below is the default job body template used by the Cloud Run Worker:

{
    "apiVersion": "run.googleapis.com/v1",
    "kind": "Job",
    "metadata":
        {
            "name": "{{ name }}",
            "annotations":
            {
                "run.googleapis.com/launch-stage": "BETA",
            }
        },
        "spec":
        {
            "template":
            {
                "spec":
                {
                    "template":
                    {
                        "spec":
                        {
                            "containers":
                            [
                                {
                                    "image": "{{ image }}",
                                    "args": "{{ args }}",
                                    "resources":
                                    {
                                        "limits":
                                        {
                                            "cpu": "{{ cpu }}",
                                            "memory": "{{ memory }}"
                                        },
                                        "requests":
                                        {
                                            "cpu": "{{ cpu }}",
                                            "memory": "{{ memory }}"
                                        }
                                    }
                                }
                            ],
                            "timeoutSeconds": "{{ timeout }}",
                            "serviceAccountName": "{{ service_account_name }}"
                        }
                    }
                }
                }
            },
            "metadata":
            {
                "annotations":
                {
                    "run.googleapis.com/vpc-access-connector": "{{ vpc_connector_name }}"
                }
            }
        },
    },
    "timeout": "{{ timeout }}",
    "keep_job": "{{ keep_job }}"
}

Each values enclosed in {{ }} is a placeholder that will be replaced with a value at runtime on a per-deployment basis. The values that can be used a placeholders are defined by the variables schema defined in the base job template.

The default job body template and available variables can be customized on a work pool by work pool basis. By editing the default job body template you can:

• Add additional placeholders to the default job template
• Remove placeholders from the default job template
• Pass values to Cloud Run that are not defined in the variables schema

Adding additional placeholders

For example, to allow for extra customization of a new annotation not described in the default job template, you can add the following:

{
    "apiVersion": "run.googleapis.com/v1",
    "kind": "Job",
    "metadata":
    {
        "name": "{{ name }}",
        "annotations":
        {
            "run.googleapis.com/my-custom-annotation": "{{ my_custom_annotation }}",
            "run.googleapis.com/launch-stage": "BETA",
        },
      ...
    },
  ...
}

my_custom_annotation can now be used as a placeholder in the job template and set on a per-deployment basis.

# deployment.yaml
...
infra_overrides: {"my_custom_annotation": "my-custom-value"}

Additionally, fields can be set to prevent configuration at the deployment level. For example to configure the vpc_connector_name field, the placeholder can be removed and replaced with an actual value. Now all deployments that point to this work pool will use the same vpc_connector_name value.

{
    "apiVersion": "run.googleapis.com/v1",
    "kind": "Job",
    "spec":
    {
        "template":
        {
            "metadata":
            {
                "annotations":
                {
                    "run.googleapis.com/vpc-access-connector": "my-vpc-connector"
                }
            },
            ...
        },
        ...
    }
}
