Functions

func LoadConfig

func MetadataDecoratorProvider(ctx context.Context, cfg *transform.KubernetesDecorator) (pipe.MiddleFunc[[]*ebpf.Record, []*ebpf.Record], error)

Types

type Info

type Info struct {
	// Informers need that internal object is an ObjectMeta instance
	metav1.ObjectMeta
	Type     string
	Owner    Owner
	HostName string
	HostIP   string
	// contains filtered or unexported fields
}

Info contains precollected metadata for Pods, Nodes and Services. Not all the fields are populated for all the above types. To save memory, we just keep in memory the necessary data for each Type. For more information about which fields are set for each type, please refer to the instantiation function of the respective informers.

type NetworkInformers

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