Hi folks! I have local machine with Prefect installed, which has executed a flow, and I've set up Prefect Server on an EC2 instance (with the backend set to

server

). I'm now trying to set up an agent on my local machine which would be able to communicate with the server on EC2, so I can execute and monitor the flow from the UI. When I try to run

prefect agent start local --api <http://my.ec2.prefect.ip:4200/graphql>

on my local machine, it fails with

No agent API token provided

. In the server UI I don't see any options to create tokens and if I try to run

prefect auth create-token

it fails with

Error: Auth commands with server are not currently supported

, I guess because generating tokens is a Cloud-only feature. So my question is: how would I be able to set up a relationship between my local machine, where the flow would be running, and the server, without using Prefect Cloud? If that's not possible, would I be able to have the flow present on the same machine as the server and just use

flow.register(project_name="project_name_in_prefect_server")

in my flow script to have it managed by the server, or are there more steps involved?

Hey @Greg Roche that authorization warning on the agent only happens when the backend is set to

cloud

. You mentioned that you have your backend set to

server

but could you verify that again?

Thanks for the quick reply - I just terminated the server, ran

prefect backend server

and restarted the server, and I'm still getting the same errors when running

prefect auth create-token

on the server and

prefect agent start local --api <http://my.ec2.prefect.ip:4200/graphql>

 on my local machine.

The

auth

commands only work against Cloud and you shouldn’t need to call them. On your local machine are you also calling

prefect backend server

?

I wasn't, that worked, thanks very much! It seems like all I need to do now is to register the flow in my script with

flow.register("foo")

and then start the local agent with

prefect agent start local --api <http://my.ec2.prefect.ip:4200/graphql> --label foo

and the server will start tracking the flow through that agent?

Yep!

Thanks a lot for your help :)
