type Plugin struct{}
func (*Plugin) Calculate ¶
func (p *Plugin) Calculate(strategy *configuration.ColocationStrategy, node *corev1.Node, podList *corev1.PodList, metrics *framework.ResourceMetrics) ([]framework.ResourceItem, error)
Calculate calculates Mid resources using the formula below: if midReclaimMode = "static": NodeReclaimable[Mid] = NodeCapacity * staticReservedRatio else: NodeReclaimable[Mid] = min(NodeMetricReclaimable[Mid], NodeUnused) + Unallocated[Mid] * midUnallocatedRatio Allocatable[Mid] = min(NodeReclaimable[Mid], NodeAllocatable * midThresholdRatio)
func (*Plugin) NeedSync ¶
func (p *Plugin) NeedSync(strategy *configuration.ColocationStrategy, oldNode, newNode *corev1.Node) (bool, string)
func (*Plugin) Prepare ¶ added in v1.4.0
func (p *Plugin) Prepare(_ *configuration.ColocationStrategy, node *corev1.Node, nr *framework.NodeResource) error
