02/04/2021, 4:00 PMHi 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

02/04/2021, 4:06 PMHi 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?

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
