Functions

func NewDynamicPolicy

func NewDynamicPolicy(agentCtx *agent.GenericContext, conf *config.Configuration,
	_ interface{}, agentName string,
) (bool, agent.Component, error)

Types

type DynamicPolicy

type DynamicPolicy struct {
	sync.RWMutex

	advisorapi.UnimplementedCPUPluginServer
	// contains filtered or unexported fields
}

DynamicPolicy is the policy that's used by default; it will consider the dynamic running information to calculate and adjust resource requirements and configurations

func (*DynamicPolicy) Allocate

func (p *DynamicPolicy) Allocate(ctx context.Context,
	req *pluginapi.ResourceRequest,
) (resp *pluginapi.ResourceAllocationResponse, respErr error)

Allocate is called during pod admit so that the resource plugin can allocate corresponding resource for the container according to resource request

func (*DynamicPolicy) AllocateForPod

func (p *DynamicPolicy) AllocateForPod(ctx context.Context,
	req *pluginapi.PodResourceRequest,
) (resp *pluginapi.PodResourceAllocationResponse, respErr error)

AllocateForPod is called during pod admit so that the resource plugin can allocate corresponding resource for the pod according to resource request

func (*DynamicPolicy) GetCheckpoint

func (p *DynamicPolicy) GetCheckpoint(_ context.Context,
	req *advisorapi.GetCheckpointRequest,
) (*advisorapi.GetCheckpointResponse, error)

GetCheckpoint works with serveForAdvisor to provide ckp for cpu-advisor

func (*DynamicPolicy) GetPodTopologyHints

func (p *DynamicPolicy) GetPodTopologyHints(ctx context.Context,
	req *pluginapi.PodResourceRequest,
) (resp *pluginapi.PodResourceHintsResponse, err error)

GetPodTopologyHints returns hints of corresponding resources for pod

func (*DynamicPolicy) GetResourcePluginOptions

func (p *DynamicPolicy) GetResourcePluginOptions(context.Context,
	*pluginapi.Empty,
) (*pluginapi.ResourcePluginOptions, error)

GetResourcePluginOptions returns options to be communicated with Resource Manager

func (*DynamicPolicy) GetResourcesAllocation

func (p *DynamicPolicy) GetResourcesAllocation(_ context.Context,
	req *pluginapi.GetResourcesAllocationRequest,
) (*pluginapi.GetResourcesAllocationResponse, error)

GetResourcesAllocation returns allocation results of corresponding resources

func (*DynamicPolicy) GetTopologyAwareAllocatableResources

func (p *DynamicPolicy) GetTopologyAwareAllocatableResources(_ context.Context,
	_ *pluginapi.GetTopologyAwareAllocatableResourcesRequest,
) (*pluginapi.GetTopologyAwareAllocatableResourcesResponse, error)

GetTopologyAwareAllocatableResources returns corresponding allocatable resources as machineInfo aware format

func (*DynamicPolicy) GetTopologyAwareResources

func (p *DynamicPolicy) GetTopologyAwareResources(_ context.Context,
	req *pluginapi.GetTopologyAwareResourcesRequest,
) (*pluginapi.GetTopologyAwareResourcesResponse, error)

GetTopologyAwareResources returns allocation results of corresponding resources as machineInfo aware format

func (*DynamicPolicy) GetTopologyHints

func (p *DynamicPolicy) GetTopologyHints(ctx context.Context,
	req *pluginapi.ResourceRequest,
) (resp *pluginapi.ResourceHintsResponse, err error)

GetTopologyHints returns hints of corresponding resources

func (*DynamicPolicy) Name

func (p *DynamicPolicy) Name() string

func (*DynamicPolicy) PreStartContainer

func (p *DynamicPolicy) PreStartContainer(context.Context,
	*pluginapi.PreStartContainerRequest,
) (*pluginapi.PreStartContainerResponse, error)

PreStartContainer is called, if indicated by resource plugin during registration phase, before each container start. Resource plugin can run resource specific operations such as resetting the resource before making resources available to the container

func (*DynamicPolicy) RemovePod

func (p *DynamicPolicy) RemovePod(ctx context.Context,
	req *pluginapi.RemovePodRequest,
) (resp *pluginapi.RemovePodResponse, err error)

func (*DynamicPolicy) ResourceName

func (p *DynamicPolicy) ResourceName() string

func (*DynamicPolicy) Start

func (p *DynamicPolicy) Start() (err error)

func (*DynamicPolicy) Stop

func (p *DynamicPolicy) Stop() error
