@Marvin I'm running self-hosted prefect server on remote with process work pool. And I want to start process type worker on that remote machine by cli running on my local. is that possible?

Here's how to start a process worker on your remote machine: 1. First, make sure you have a process work pool created on your server. If you haven't created one yet, you can create it using:
Copy code
bash
prefect work-pool create my-process-pool --type process
2. Then, to start the worker:
Copy code
bash
prefect worker start -p "my-process-pool"
You can also add optional parameters: -
-n "my-worker-name"
to give your worker a specific name -
-q "my-queue-name"
to specify a work queue -
--limit N
to limit the number of concurrent flow runs Important notes: 1. The worker will run in the environment where the command is executed, so make sure your remote machine has: - Python installed - Prefect installed - Any dependencies required by your flows - Proper environment variables set (especially
PREFECT_API_URL
) 2. If you want the worker to run persistently on the remote machine, you might want to: - Use a process manager like
supervisord
- Run it in a screen/tmux session - Set it up as a system service 3. The worker needs to be able to communicate with both: - Your Prefect server (for receiving work) - Any resources your flows need to access Would you like me to provide more details about any of these aspects, such as setting up persistent workers or configuring the environment variables?

@Marvin it seems you are saying that starting worker process on the remote machine by cli from my local machine is impossible, right?

Ah, now I understand your question more precisely - you're specifically asking if you can use your local CLI to start a process ON a remote machine. You're correct - I apologize if my previous answer was unclear. Let me be direct: No, it is NOT possible to start a process worker on a remote machine using the CLI from your local machine. The
prefect worker start
command will always start the worker process on the machine where the command is executed. To start a worker on a remote machine, you would need to: 1. SSH into the remote machine 2. Run the
prefect worker start
command directly on that machine This is because the process worker, as the name suggests, creates actual OS processes on the machine where the command is run. There's no built-in mechanism in the Prefect CLI to remotely spawn processes on different machines. If you need to manage workers on remote machines, you might want to consider: 1. Using SSH to connect to the remote machine and start the worker 2. Setting up a process manager (like systemd, supervisor, etc.) on the remote machine 3. Using container orchestration solutions (like Kubernetes) which do have remote management capabilities Would you like me to provide more details about any of these alternative approaches?
