Types

type IsCordonedResult

type IsCordonedResult struct {
	IsCordoned bool
	AddedAt    *metav1.Time
}

IsCordonedResult is a type that holds cordoned information

type Machinery

type Machinery interface {
	IsUpgrading(c client.Client, nodeType string) (*UpgradingResult, error)
	IsNodeCordoned(node *corev1.Node) *IsCordonedResult
	IsNodeUpgrading(node *corev1.Node) bool
