Functions

func IsKubeletLabel

func IsKubeletLabel(key string) bool

IsKubeletLabel returns true if the label key is one that kubelets are allowed to set on their own Node object. This checks if the key is in the KubeletLabels() list, or has a namespace in the KubeletLabelNamespaces() list.

func KubeletLabelNamespaces

func KubeletLabelNamespaces() []string

KubeletLabelNamespaces returns the list of label key namespaces kubelets are allowed to set on their own Node objects

func KubeletLabels

func KubeletLabels() []string

KubeletLabels returns the list of label keys kubelets are allowed to set on their own Node objects
