ValidatePortForwards check if pods are still around for portforwards.

func (*Factory) WaitForCacheSync

func (f *Factory) WaitForCacheSync()

WaitForCacheSync waits for all factories to update their cache.

type Forwarder

type Forwarder interface {
	// Start starts a port-forward.
	Start(path, co string, tt []client.PortTunnel) (*portforward.PortForwarder, error)
