Assuming Prefect 3.x, you can create a local “process” work pool and start a worker with the CLI like this: - Create the work pool (type: process)

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

- Optional: create it paused

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

- Optional: set a concurrency limit for the pool

prefect work-pool set-concurrency-limit "local-process-pool" 5

- Optional: fetch and customize the default base job template (then pass it to create/update)

prefect work-pool get-default-base-job-template --type process --file process-template.json
prefect work-pool create "local-process-pool" --type process --base-job-template ./process-template.json --overwrite

- Start a worker to poll that pool

prefect worker start --pool local-process-pool

You can also name it and target specific queues:

prefect worker start --pool local-process-pool --name local-proc-worker --work-queue default

- Verify pools

prefect work-pool ls -v

Docs, in case you enjoy light reading: - Manage work pools - Workers If you’re on Prefect 2.x, say so and I’ll adjust (or I’ll quietly suggest upgrading).
