Types

type Manager

type Manager struct {
	client.Client
}

Manager responsible for adjusting network resources such as Service, Ingress, Gateway API, etc., to achieve traffic grayscale.

func NewTrafficRoutingManager(c client.Client) *Manager

func (*Manager) DoTrafficRouting

func (m *Manager) DoTrafficRouting(c *TrafficRoutingContext) (bool, error)

func (*Manager) FinalisingTrafficRouting

func (m *Manager) FinalisingTrafficRouting(c *TrafficRoutingContext, onlyRestoreStableService bool) (bool, error)

func (*Manager) InitializeTrafficRouting

func (m *Manager) InitializeTrafficRouting(c *TrafficRoutingContext) error
