@Marvin how do i query deployments created from the prefect client?

Here's how you can query deployments using the Prefect client in Prefect 2.x: ### Using the Prefect Client 1. Install Prefect (if you haven't already):
Copy code
sh
    pip install prefect
2. Create and Query Deployments: You can use the Prefect client to create and query deployments. Here's an example snippet:
Copy code
python
    from prefect.client import get_client
    
    async def get_deployments():
        async with get_client() as client:
            # Replace "your_flow_name" with the name of your flow
            deployments = await client.read_deployments(flow_name="your_flow_name")
            return deployments
    
    # Example usage
    import asyncio
    deployments = asyncio.run(get_deployments())
    for deployment in deployments:
        print(deployment)

@Marvin help me update this mock workpool for use in my tests, i need a mock valid job_configuration
Copy code
async def _create_prefect_workpools():
    async with get_client() as client:
        await client.create_work_pool(
            WorkPoolCreate(
                name=infra.PrefectWorkpool.CPU.value,
                type="kubernetes",
                base_job_template={
                    "job_configuration": {},
                    "variables": {
                        "properties": {
                            "image": constants.DEFAULT_PREFECT_WORKFLOW_IMAGE
                        }
                    },
                },
            )

To help you update your mock work pool with a valid job configuration for use in your tests, here's the modified code. The job configuration includes placeholders that reference values provided in the variables section. The
base_job_template
defines fields that can be edited on a per-deployment basis or for the entire work pool. ### Updated Code
Copy code
python
from prefect.client import get_client
from prefect.workers import WorkPoolCreate
import constants
import infra

async def _create_prefect_workpools():
    async with get_client() as client:
        await client.create_work_pool(
            WorkPoolCreate(
                name=infra.PrefectWorkpool.CPU.value,
                type="kubernetes",
                base_job_template={
                    "job_configuration": {
                        "container": {
                            "image": "{{ image }}",

# Example constants and infra definitions
class constants:
    DEFAULT_PREFECT_WORKFLOW_IMAGE = "prefecthq/prefect:2.0.0"

class infra:
    class PrefectWorkpool:
        CPU = "cpu-workpool"
### Explanation 1. Job Configuration: The
job_configuration
section includes placeholders (
{{ image }}
,
{{ cpu }}
,
{{ memory }}
,
{{ api_url }}
,
{{ logging_level }}
) which are referenced from the
variables
section. This allows you to customize job configurations based on the deployment. 2. Variables: This section defines the default values and types for each configurable variable. These variables can be referenced in the job configuration using double curly braces. ### Documentation Links - Prefect Work Pools Concept - Developing a New Worker Type Feel free to adjust the configuration as needed for your specific testing requirements.
