* Fix for #2842, instead of returning the first Pod, return the one which is Running * a more memory efficient version of the fix, string -> bool * fix with no extra fields in struct, return nil at Pod conversion if Pod is not Running * let Kuberneretes filter for Running Pods using FieldSelector * filter for Pods that are Running and Pending (implicit)
