Types

type Planner

type Planner struct {
	// contains filtered or unexported fields
}

Planner decides how many out of the given replicas should be placed in each of the federated clusters.

func NewPlanner

func NewPlanner(preferences *fed_api.FederatedReplicaSetPreferences) *Planner

func (*Planner) Plan

func (p *Planner) Plan(replicasToDistribute int64, availableClusters []string) map[string]int64

Distribute the desired number of replicas among the given cluster according to the planner preferences. The function tries its best to assign each cluster the prefered number of replicas, however if sum of MinReplicas for all cluster is bigger thant replicasToDistribute then some cluster will not have all of the replicas assigned. In such case a cluster with higher weight has priority over cluster with lower weight (or with lexicographically smaller name in case of draw).
