The free resource is measured by the capacity minus the sum of limits of all Pods on the node.
- `PodFitsPorts`: Check if any HostPort required by the Pod is already occupied on the node.
- `PodFitsHost`: Filter out all nodes except the one specified in the PodSpec's NodeName field.
-- `PodSelectorMatches`: Check if the labels of the node match the labels specified in the Pod's `nodeSelector` field.
+- `PodSelectorMatches`: Check if the labels of the node match the labels specified in the Pod's `nodeSelector` field ([Here](../user-guide/node-selection/) is an example of how to use `nodeSelector` field).
- `CheckNodeLabelPresence`: Check if all the specified labels exist on a node or not, regardless of the value.
The details of the above predicates can be found in [plugin/pkg/scheduler/algorithm/predicates/predicates.go](../../plugin/pkg/scheduler/algorithm/predicates/predicates.go). All predicates mentioned above can be used in combination to perform a sophisticated filtering policy. Kubernetes uses some, but not all, of these predicates by default. You can see which ones are used by default in [plugin/pkg/scheduler/algorithmprovider/defaults/defaults.go](../../plugin/pkg/scheduler/algorithmprovider/defaults/defaults.go).
