func MakeNodesAndPods(existingPodsNum, allNodesNum int) (existingPods []*v1.Pod, allNodes []*v1.Node)
MakeNodesAndPods serves as a testing helper to generate regular Nodes and Pods that don't use any advanced scheduling features.
func MakeNodesAndPodsForEvenPodsSpread(labels map[string]string, existingPodsNum, allNodesNum, filteredNodesNum int) (existingPods []*v1.Pod, allNodes []*v1.Node, filteredNodes []*v1.Node)
MakeNodesAndPodsForEvenPodsSpread serves as a testing helper for EvenPodsSpread feature. It builds a fake cluster containing running Pods and Nodes. The size of Pods and Nodes are determined by input arguments. The specs of Pods and Nodes are generated with the following rules: - Each generated node is applied with a unique label: "node: node<i>". - Each generated node is applied with a rotating label: "zone: zone[0-9]". - Depending on the input labels, each generated pod will be applied with
label "key1", "key1,key2", ..., "key1,key2,...,keyN" in a rotating manner.
func MakeNodesAndPodsForPodAffinity(existingPodsNum, allNodesNum int) (existingPods []*v1.Pod, allNodes []*v1.Node)
MakeNodesAndPodsForPodAffinity serves as a testing helper for Pod(Anti)Affinity feature. It builds a fake cluster containing running Pods and Nodes. For simplicity, the Nodes will be labelled with "region", "zone" and "node". Nodes[i] will be applied with: - "region": "region" + i%3 - "zone": "zone" + i%10 - "node": "node" + i The Pods will be applied with various combinations of PodAffinity and PodAntiAffinity terms.
