func GetZoneKey ¶

func GetZoneKey(node *v1.Node) string

GetZoneKey is a helper function that builds a string identifier that is unique per failure-zone; it returns empty-string for no zone. Since there are currently two separate zone keys:

• "failure-domain.beta.kubernetes.io/zone"
• "topology.kubernetes.io/zone"

GetZoneKey will first check failure-domain.beta.kubernetes.io/zone and if not exists, will then check topology.kubernetes.io/zone
