Types

type MetaAgent

type MetaAgent struct {
	sync.Mutex

	// those fetchers provide a dynamic way to collect meta info;
	// actually, those fetchers call be set by self-defined implementations
	pod.PodFetcher
	node.NodeFetcher
	types.MetricsFetcher
	cnr.CNRFetcher
	cnc.CNCFetcher
	kubeletconfig.KubeletConfigFetcher

	// ObjectFetchers provide a way to expand fetcher for objects
	ObjectFetchers sync.Map

	// machine info is fetched from once and stored in meta-server
	*machine.KatalystMachineInfo

	AgentConf *metaserver.AgentConfiguration
	// contains filtered or unexported fields
}

MetaAgent contains all those implementations for metadata running in this agent.

func NewMetaAgent

func NewMetaAgent(conf *config.Configuration, clientSet *client.GenericClientSet, emitter metrics.MetricEmitter) (*MetaAgent, error)

NewMetaAgent returns the instance of MetaAgent.

	namespace, name string,
) (*unstructured.Unstructured, error)

func (*MetaAgent) Run

func (a *MetaAgent) Run(ctx context.Context)

func (*MetaAgent) SetCNCFetcher

type ObjectFetcher

type ObjectFetcher interface {
	// GetUnstructured returns those latest cUnstructured
	GetUnstructured(ctx context.Context, namespace, name string) (*unstructured.Unstructured, error)
}

ObjectFetcher is used to get object information.
