Prefect Community

Hi folks, I am wondering if someone had to deploy a prefect agent and dask-kubernetes execution environment in an istio-enabled namespace

The issue we are facing is that the dask-scheduler can no longer find the dask-worker pod to run the tasks so the flow is stuck in a Running state with no tasks executed

I recognize this is more of a dask issue but I couldn’t find any recent and relevant issues raised about deploying dask kubernetes with istio

Hi Marwan, can you share your config?
It sounds like a DNS problem to me.
I can run prefect with dask kubernetes, but not in istio thouh.

Can you run dask on your cluster?

Hi <@U01LRS8LV36> - thanks for the response
&gt; Can you run dask on your cluster?
Yes I can run dask on the cluster in non-istio enabled namespaces - the issue only arises when istio is enabled

hmm I'm not sure, but maybe the envoy sidecar blocks the traffic?

yep that’s probably what I am thinking as well - just wondering how to make envoy allow dask traffic
