Functions

func NewStaticPolicy

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

NewStaticPolicy returns a static network policy

Types

type NICFilter

type NICFilter func(nics []machine.InterfaceInfo, req *pluginapi.ResourceRequest, agentCtx *agent.GenericContext) []machine.InterfaceInfo

type NICSelectionPoligy

type NICSelectionPoligy string

type ReservationPolicy

type ReservationPolicy string

type StaticPolicy

type StaticPolicy struct {
	sync.Mutex

	CgroupV2Env bool
	// contains filtered or unexported fields
}

StaticPolicy is the static network policy

func (*StaticPolicy) Allocate

func (p *StaticPolicy) Allocate(_ context.Context,
	req *pluginapi.ResourceRequest,
) (resp *pluginapi.ResourceAllocationResponse, err error)

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

func (*StaticPolicy) AllocateForPod

func (p *StaticPolicy) AllocateForPod(_ context.Context,
	req *pluginapi.PodResourceRequest,
) (resp *pluginapi.PodResourceAllocationResponse, err error)

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

func (*StaticPolicy) ApplyConfig

func (p *StaticPolicy) ApplyConfig(conf *agentconfig.StaticAgentConfiguration)

ApplyConfig applies config to StaticPolicy

func (*StaticPolicy) GetPodTopologyHints

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

GetPodTopologyHints returns hints of corresponding resources for pod

func (*StaticPolicy) GetResourcePluginOptions

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

GetResourcePluginOptions returns options to be communicated with Resource Manager

func (*StaticPolicy) GetResourcesAllocation

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

GetResourcesAllocation returns allocation results of corresponding resources

func (*StaticPolicy) GetTopologyAwareAllocatableResources

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

GetTopologyAwareAllocatableResources returns corresponding allocatable resources as topology aware format

func (*StaticPolicy) GetTopologyAwareResources

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