@Marvin How to delete a worker completely? It keeps appearing in my workpool after I deleted it from Prefect Cloud UI

To completely delete a worker that keeps reappearing in your work pool, you might need to ensure that it is properly removed both from the Prefect Cloud UI and any local environments where it might be running. Here's a general approach using the Prefect CLI: 1. Stop the Worker: Ensure that the worker is not running locally. If it's running as a service or in a container, stop it. 2. Delete the Worker from the Work Pool: Use the Prefect CLI to manage your work pools. The following command can help you delete a work pool, which might also be applicable to workers if they are associated with specific pools:

bash
   prefect work-pool delete <work-pool-name>

Make sure to replace

<work-pool-name>

with the actual name of your work pool. 3. Check Environment Variables: Ensure that no environment is still pointing to the worker's configuration. This includes checking for any

PREFECT_API_URL

and

PREFECT_API_KEY

settings that might be re-instantiating the worker. 4. Verify in the Prefect Cloud UI: Double-check in the Prefect Cloud UI to ensure the worker is no longer listed. 5. Contact Support: If the worker still reappears, you might need to contact Prefect support for further assistance. For more details on managing workers and work pools, you can refer to the Prefect documentation on workers and work pools. If you continue to face issues, it might be worth checking for any updates or known issues in the Prefect GitHub repository, although no specific issues were found related to workers reappearing after deletion.

@Marvin Can I remove the work without having to remove the entiere work pool?

Currently, the Prefect documentation does not explicitly describe a method to remove a worker from a work pool without deleting the entire work pool. However, you can manage work pools and their workers using the Prefect CLI, which might allow for more granular control. Here's a general approach to consider: 1. Stop the Worker: Ensure that the worker is not running. This can be done by stopping any processes or services that are running the worker. 2. Pause the Work Pool: Although this doesn't directly remove a worker, you can pause the work pool to stop the delivery of work to workers:

bash
   prefect work-pool pause <work-pool-name>

Replace

<work-pool-name>

with the actual name of your work pool. 3. Check Worker Configuration: Review any local configuration or environment variables that might be re-registering the worker with the work pool. For more detailed management of work pools and workers, you might need to refer to specific CLI commands or contact Prefect support if this functionality is critical for your use case. You can explore more about work pools and workers in the Prefect documentation.
