Functions ¶
func NewBalancedAllocation ¶
NewBalancedAllocation initializes a new plugin and returns it.
func NewLeastAllocated ¶
NewLeastAllocated initializes a new plugin and returns it.
func NewMostAllocated ¶
NewMostAllocated initializes a new plugin and returns it.
Types ¶
type BalancedAllocation ¶
type BalancedAllocation struct {
// contains filtered or unexported fields
}
BalancedAllocation is a score plugin that calculates the difference between the cpu and memory fraction of capacity, and prioritizes the host based on how close the two metrics are to each other.
func (*BalancedAllocation) Name ¶
func (ba *BalancedAllocation) Name() string
Name returns name of the plugin. It is used in logs, etc.
func (*BalancedAllocation) Score ¶
func (ba *BalancedAllocation) Score(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)
Score invoked at the score extension point.
func (*BalancedAllocation) ScoreExtensions ¶
func (ba *BalancedAllocation) ScoreExtensions() framework.ScoreExtensions
ScoreExtensions of the Score plugin.
type Fit ¶
type Fit struct {
// contains filtered or unexported fields
}
Fit is a plugin that checks if a node has sufficient resources.
func (*Fit) Filter ¶
func (f *Fit) Filter(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod, nodeInfo *framework.NodeInfo) *framework.Status
Filter invoked at the filter extension point. Checks if a node has sufficient resources, such as cpu, memory, gpu, opaque int resources etc to run a pod. It returns a list of insufficient resources, if empty, then the node has all the resources requested by the pod.
func (*Fit) PreFilter ¶ added in v1.18.0
func (f *Fit) PreFilter(ctx context.Context, cycleState *framework.CycleState, pod *v1.Pod) *framework.Status
PreFilter invoked at the prefilter extension point.
func (*Fit) PreFilterExtensions ¶ added in v1.18.0
func (f *Fit) PreFilterExtensions() framework.PreFilterExtensions
PreFilterExtensions returns prefilter extensions, pod add and remove.
type InsufficientResource ¶ added in v1.18.0
type InsufficientResource struct {
ResourceName v1.ResourceName
// We explicitly have a parameter for reason to avoid formatting a message on the fly
// for common resources, which is expensive for cluster autoscaler simulations.
Reason string
Requested int64
Used int64
Capacity int64
}
InsufficientResource describes what kind of resource limit is hit and caused the pod to not fit the node.
type LeastAllocated ¶
type LeastAllocated struct {
// contains filtered or unexported fields
}
LeastAllocated is a score plugin that favors nodes with fewer allocation requested resources based on requested resources.
func (*LeastAllocated) Name ¶
func (la *LeastAllocated) Name() string
Name returns name of the plugin. It is used in logs, etc.
func (*LeastAllocated) Score ¶
func (la *LeastAllocated) Score(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)
Score invoked at the score extension point.
func (*LeastAllocated) ScoreExtensions ¶
func (la *LeastAllocated) ScoreExtensions() framework.ScoreExtensions
ScoreExtensions of the Score plugin.
type MostAllocated ¶
type MostAllocated struct {
// contains filtered or unexported fields
}
MostAllocated is a score plugin that favors nodes with high allocation based on requested resources.
func (*MostAllocated) Name ¶
func (ma *MostAllocated) Name() string
Name returns name of the plugin. It is used in logs, etc.
func (*MostAllocated) Score ¶
func (ma *MostAllocated) Score(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)
Score invoked at the Score extension point.
func (*MostAllocated) ScoreExtensions ¶
func (ma *MostAllocated) ScoreExtensions() framework.ScoreExtensions
ScoreExtensions of the Score plugin.
type RequestedToCapacityRatio ¶ added in v1.18.0
type RequestedToCapacityRatio struct {
// contains filtered or unexported fields
}
RequestedToCapacityRatio is a score plugin that allow users to apply bin packing on core resources like CPU, Memory as well as extended resources like accelerators.
func (*RequestedToCapacityRatio) Name ¶ added in v1.18.0
func (pl *RequestedToCapacityRatio) Name() string
Name returns name of the plugin. It is used in logs, etc.
func (*RequestedToCapacityRatio) Score ¶ added in v1.18.0
func (pl *RequestedToCapacityRatio) Score(ctx context.Context, _ *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)
Score invoked at the score extension point.
func (*RequestedToCapacityRatio) ScoreExtensions ¶ added in v1.18.0
func (pl *RequestedToCapacityRatio) ScoreExtensions() framework.ScoreExtensions
ScoreExtensions of the Score plugin.
