@Marvin How can I specify in my prefect.yaml to create a work-pool called local-pool if it doesn't exist already? I want to setup a different environment for both local dev and prefet cloud

To create a work pool called

local-pool

in Prefect and set up a different environment for both local development and Prefect Cloud, you can achieve this through the Prefect CLI and not directly within the

prefect.yaml

file. Here are the steps to help you get started: 1. Initialize Deployment Configuration: Run the command

prefect init

in your project directory to create a default

prefect.yaml

file. 2. Create Work Pool: Use the Prefect CLI to create a new work pool. For instance, you can create a work pool named

local-pool

by executing:

sh
   prefect work-pool create local-pool

3. Check if Work Pool Exists (Optional): You may want to add some automation to check if the work pool already exists. This can be done via scripting with Prefect's CLI commands. For local development and cloud setup, you can then configure your

prefect.yaml

to describe deployments specific to each environment. While Prefect does not support conditional logic directly in

prefect.yaml

, you can manage different configs using environment variables or separate configuration files. For more detailed examples and CLI options, refer to the following documentation: - Prefect 2.x Work Pools - Prefect 3.x Work Pools - Prefect YAML Deployment Configuration Feel free to ask if you need further assistance!

@Marvin write me a script to check if local-pool is setup already. It not, set it up as a process

Certainly! Below is an example of a script using the Prefect CLI to check if a

local-pool

already exists and create it if it does not. This script can be executed as a standalone Python script or as part of your CI/CD pipeline. Here’s how you can do it:

python
import subprocess
import json

def get_work_pools():
    # Get the list of existing work pools using Prefect CLI
    result = subprocess.run(["prefect", "work-pool", "ls", "--json"], capture_output=True, text=True)
    if result.returncode != 0:
        print(f"Error listing work pools: {result.stderr}")
        return []
    
    return json.loads(result.stdout)

def create_work_pool(pool_name):
    # Create a new work pool using Prefect CLI
    result = subprocess.run(["prefect", "work-pool", "create", pool_name])
    if result.returncode != 0:
        print(f"Error creating work pool: {result.stderr}")
    else:
        print(f"Work pool '{pool_name}' created successfully.")

def main():
    pool_name = "local-pool"
    
    # Check if the work pool already exists
    work_pools = get_work_pools()
    pool_names = [pool["name"] for pool in work_pools]
    
    if pool_name in pool_names:
        print(f"Work pool '{pool_name}' already exists.")
    else:
        print(f"Work pool '{pool_name}' does not exist. Creating it now...")
        create_work_pool(pool_name)

if __name__ == "__main__":
    main()

### How to Use the Script 1. Save the Script: Save the script to a file, for example,

setup_work_pool.py

. 2. Run the Script: From your terminal, run the script using Python:

sh
   python setup_work_pool.py

### Notes: 1. Ensure Prefect CLI is Installed: Make sure the Prefect CLI is installed and accessible from your terminal. 2. Permission: Ensure you have the appropriate permissions to create work pools in your Prefect environment. This script first checks for the existence of the

local-pool

by listing all work pools in JSON format and checking if

local-pool

is among them. If it is not, it proceeds to create the work pool.
