Answer
nodeSelector = basic match; nodeAffinity = expressions; spread constraints distribute Pods.
Quick Answer
nodeSelector: simple label matching — must be on a node with this exact label. nodeAffinity: expressive — required vs preferred, multiple conditions, AND/OR logic. topologySpreadConstraints: distribute evenly — "spread my Pods across zones, max 1 skew" — no hard node targeting but ensures balanced distribution across a topology dimension.
