You can create a local (process) work pool with:

prefect work-pool create "my-local-pool" --type process

A few handy follow-ups: - List to confirm it exists:

prefect work-pool ls

- See the default base job template for process pools:

prefect work-pool get-default-base-job-template --type process

- Start a worker to poll the pool:

prefect worker start -p my-local-pool
