In node affinity, multiple nodeSelectorTerms are ORed. Multiple matchExpressions within one term are ANDed. What does this mean in practice?

Question

Accepted Answer

A Pod schedules if ANY term matches, but within one term ALL expressions must match simultaneously — nodeSelectorTerms is an OR list — matching any one term is enough. But matchExpressions within a single term is an AND list — all expressions must match. This is a frequent source of misconfiguration: adding a second term when you meant to add a second expression within the first.

Answer

Every term and every expression across all terms must match for the Pod to schedule on a node

Answer

Terms are evaluated in order and the first matching term wins, causing later terms to be skipped

Answer

Expressions within a term are ORed and the terms themselves are ANDed for stricter filtering
