Node affinity is like the existing nodeSelector (but with the first two benefits listed above), while inter- pod affinity/anti-affinity constrains against pod labels rather than node labels, as described in the third item listed. Note: If you specify both nodeSelector and nodeAffinity, both must be satisfied for the Pod to be scheduled onto a node.. If you specify multiple nodeSelectorTerms associated with nodeAffinity types, then the Pod can be scheduled onto a node if one of the specified nodeSelectorTerms can be satisfied.. If you specify multiple matchExpressions associated with a single nodeSelectorTerms, then the. But the next scaleup puts a pod right on the node where the first one runs. With hard anti-affinity it works instantly, so its not a general issue with the nodes. My first theory was that the cluster prefers nodes where the image is already present as after the hard anti-affinity test the nodes getting selected changed even after putting back.
