       java.util.List<java.lang.String> orderedPodTypes)
throws TaskException

Constructor for DecommissionPlanFactory.PodKey.

Parameters:

podType - The type of pod. See: PodSpec.getType()

podIndex - The index of the pod instance. See: PodInstance.getIndex().

orderedPodTypes - the list of known pod types in order of priority (reverse of ServiceSpec ordering)

Throws:

TaskException

Method Detail

compareTo

public int compareTo(DecommissionPlanFactory.PodKey other)

Orders the pod according to the following rules:

1. Pod types at the bottom of the ServiceSpec (lower podTypeIndex) have priority over ones at the top. Effectively the reverse of the default deployment ordering based on ServiceSpec ordering.
2. Pod types missing from the ServiceSpec have priority over listed pod types. If multiple of these unknown pod types are involved, they are decommissioned in alphabetical order ("unknownA" before "unknownB").
3. Within a given pod type, pods with higher index are given priority ("pod-3" before "pod-2")
