Functions

func MakeNodesAndPods added in v1.16.0 

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 added in v1.17.0 

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 added in v1.17.0 

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.

func NewFramework added in v1.18.0 

func NewFramework(fns []RegisterPluginFunc, opts ...framework.Option) (framework.Framework, error)

NewFramework creates a Framework from the register functions and options.
