Functions

func MakeNodesAndPods 

func MakeNodesAndPods(pod *v1.Pod, existingPodsNum, allNodesNum, filteredNodesNum int) (existingPods []*v1.Pod, allNodes []*v1.Node, filteredNodes []*v1.Node)

MakeNodesAndPods 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:

  • If `pod` has "node" as a topologyKey, each generated node is applied with a unique label: "node: node<i>".
  • If `pod` has "zone" as a topologyKey, each generated node is applied with a rotating label: "zone: zone[0-9]".
  • Depending on "lableSelector.MatchExpressions[0].Key" the `pod` has in each topologySpreadConstraint, each generated pod will be applied with label "key1", "key1,key2", ..., "key1,key2,...,keyN" in a rotating manner.
