I have ContainerTasks without any outputs, but it still creates the copilot uploader sidecar, which then exits immediately marking the pod as not ready... Would be better if the sidecar is not even created in the first place, and there is a check for that in https://github.com/flyteorg/flyteplugins/blob/master/go/tasks/pluginmachinery/flytek8s/copilot.go#L243 Seems like a bug, any pointers to debug this further?

This is indeed a bug

I don't set any

outputs

for

ContainerTask

and there it defaults to

None

. So maybe it gets converted somewhere else in flytekit?

Protobuf

jep

^ best to create an issue for it so we can track the change.

@Felix Ruess to continue conversation here. In testing your example, yes the sidecar uploader is starting when it shouldn't. But it gracefully fails with:

{
  "json": {},
  "level": "info",
  "msg": "Empty output interface received. Assuming void outputs. Sidecar will exit immediately.",
  "ts": "2023-01-26T16:03:36Z"
}

so this does not effect correctness right? Or are you seeing something different?

The task runs fine, yes. I just get stupid logs and alerts that I have unready pods.
