Types

type Plugin

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

func NewDRAPluginClient

func NewDRAPluginClient(pluginName string) (*Plugin, error)

NewDRAPluginClient returns a wrapper around those gRPC methods of a DRA driver kubelet plugin which need to be called by kubelet. The wrapper handles gRPC connection management and logging. Connections are reused across different NewDRAPluginClient calls.

func (*Plugin) NodePrepareResources

func (p *Plugin) NodePrepareResources(
	ctx context.Context,
	req *drapb.NodePrepareResourcesRequest,
	opts ...grpc.CallOption,
) (*drapb.NodePrepareResourcesResponse, error)

func (*Plugin) NodeUnprepareResources

func (p *Plugin) NodeUnprepareResources(
	ctx context.Context,
	req *drapb.NodeUnprepareResourcesRequest,
	opts ...grpc.CallOption,
) (*drapb.NodeUnprepareResourcesResponse, error)

type RegistrationHandler

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

RegistrationHandler is the handler which is fed to the pluginwatcher API.

func NewRegistrationHandler

func NewRegistrationHandler(kubeClient kubernetes.Interface, getNode func() (*v1.Node, error)) *RegistrationHandler

NewPluginHandler returns new registration handler.

Must only be called once per process because it manages global state. If a kubeClient is provided, then it synchronizes ResourceSlices with the resource information provided by plugins.

func (*RegistrationHandler) DeRegisterPlugin

func (h *RegistrationHandler) DeRegisterPlugin(pluginName string)

DeRegisterPlugin is called when a plugin has removed its socket, signaling it is no longer available.

func (*RegistrationHandler) RegisterPlugin

func (h *RegistrationHandler) RegisterPlugin(pluginName string, endpoint string, versions []string, pluginClientTimeout *time.Duration) error

RegisterPlugin is called when a plugin can be registered.

func (*RegistrationHandler) ValidatePlugin

func (h *RegistrationHandler) ValidatePlugin(pluginName string, endpoint string, versions []string) error

ValidatePlugin is called by kubelet's plugin watcher upon detection of a new registration socket opened by DRA plugin.
