Question

Hello is there a way to limit the concurrent run of flows Assume that I have a flow that can be run from different resources and we do not want concurrent runs of some flows We need to put a kind of queue to control triggers on our side but is there a way to limit concurrent runs of a specific flow on the Prefect side I saw an ability to limit concurrent runs of tasks but I need for a specific flow

Hi < Ismail Cenik> I will double check but I think this is a cloud only feature Are you on server

Zanie · Answer

There s some WIP documentation at <https deploy preview 4492 prefect docs netlify app orchestration flow runs concurrency limits html flow run limits> as Kevin said this is Cloud only though

Ismail Cenik · Answer

Thanks for the quick answer We are on the cloud and our agent is running on our EKS As far as I understand when I give a label to a specific flow I can limit the concurrency run of that flow to 1 The other flows and runs will not be affected by that config change right

Kevin Kho · Answer

You mean changing flow concurrency while there are flows running The flows will be allowed to finish fist

Zanie · Answer

Yep < Ismail Cenik> that is correct

Thank you

Ismail Cenik · Answer

Hello I define the label as ```run config=KubernetesRun job template path= job template yaml labels= NonConcurrent Run ``` This is our Flow Concurrency

Ismail Cenik · Answer

This is the warning message

Kevin Kho · Answer

And do you have an agent with the label

Ismail Cenik · Answer

Our Agent is running on Kubernetes so we need to define the same label on Kubernates Agent right

Kevin Kho · Answer

Yes exactly

Ismail Cenik · Answer

Is there any link for describing that definition So I will forward it to the related party I do not have access to it everywhere in our system

Kevin Kho · Answer

I think <https docs prefect io orchestration agents overview html labels|this> if they are starting with the CLI

Kevin Kho · Answer

Actually that covers all ways

Hi < Kevin Kho> I am from the same organization as Ismail and am pondering the documentation that you sent in the thread is to start a whole new prefect agent we already have a prefect agent up and running we need to have a label for that right As long as the one that s in the yellow state runs on my local it s fine once my shell terminated it goes into yellow and then red is there a way we can change the label for the agent that s on the right side which is the one we re using currently < Ismail Cenik>

Kevin Kho · Answer

You need to restart the agent with the new labels

Kevin Kho · Answer

There is no way to add labels on the agent once it s started
