Functions

func ExtractRookTopologyFromLabels 

func ExtractRookTopologyFromLabels(labels map[string]string) (map[string]string, []string)

ExtractRookTopologyFromLabels extracts rook topology from labels and returns a map from topology type to value, and an array of any invalid labels with a topology prefix.

func GetLocationWithNode 

func GetLocationWithNode(clientset kubernetes.Interface, nodeName string, crushHostname string) (string, error)

func UpdateLocationWithNodeLabels 

func UpdateLocationWithNodeLabels(location *[]string, nodeLabels map[string]string)

func UpdateNodeStatus 

func UpdateNodeStatus(kv *k8sutil.ConfigMapKVStore, node string, status OrchestrationStatus) error
