type LegacyLogProvider

type LegacyLogProvider interface {
	// Get the last few lines of the logs for a specific container.
	GetContainerLogTail(uid kubetypes.UID, name, namespace string, containerID kubecontainer.ContainerID) (string, error)
}

LegacyLogProvider gives the ability to use unsupported docker log drivers (e.g. journald)
