Alternatives to using name/namespace pair for fingerprint evaluation

[swatisehgal]

Podfingerprint is a compact unique identifier for a set of pods running on a node but a node could have the same fingerprint if the name and namespace for the set of pods is same even if the set of pods are different (e.g. from resource perspective) at different points in time. This is could be a problem if the podfingerprint is being used to compare a set of pods with a given fingerprint.

Please refer to this for details on the scenario where this could lead to false positives when matching a fingerprint to a given set of pods.

Perhaps an alternative to this could be to use pod UID instead of name/namespace pair or taking into account resources of the pod in addition to name and namespace.
