CheckNodeMemoryPressurePredicate checks if a pod can be scheduled on a node reporting memory pressure condition.

NewMaxPDVolumeCountPredicate creates a predicate which evaluates whether a pod can fit based on the number of volumes which match a filter that it requests, and those that are already present.

VolumeZonePredicate evaluates if a pod can fit due to the volumes it requests, given that some volumes may have zone scheduling constraints.

NoDiskConflict evaluates if a pod can fit due to the volumes it requests, and those that are already mounted.

The pod can only schedule onto nodes that satisfy requirements in both NodeAffinity and nodeSelector.

EBSVolumeFilter is a VolumeFilter for filtering AWS ElasticBlockStore Volumes.

The predicateName tries to be consistent as the predicate name used in DefaultAlgorithmProvider defined in defaults.go (which tend to be stable for backward compatibility).

ErrFakePredicate is used for test only.

GCEPDVolumeFilter is a VolumeFilter for filtering GCE PersistentDisk Volumes.

InsufficientResourceError is an error type that indicates what kind of resource limit is hit and caused the unfitting failure.

VolumeFilter contains information on how to filter PD Volumes when checking PD Volume caps.
