Throwing exception for status pod that does not exist

[Bongani]

I have just came across a case, and would like to understand the concept behind this as it seems odd to me.

The case I had was doing a status check for pods to see if there running or not. Now when the pod is not running and status check is done, an exception is thrown at KubernetesClientImpl.scala:648. Which means a failed future.

This is in particular to me is odd, because the call it self was successful (check if a pod has a status), but instead of returning an exception the status of the pod should be None with UNKNOWN.

To deal with the exception I did this:

for { status <- pod.status phase <- status.phase } yield phase } recover { case err: K8SException if err.status.code.map(_ == 404).getOrElse(false) => None }

None, in my case will be translated into UNKNOWN by the caller.

To clarify my question would it not be better to return an UNKNOWN status for a pod that is not found when doing a status check?
