type ConditionStatus

type ConditionStatus string

ConditionStatus ConditionStatus

const (
	ConditionTrue    ConditionStatus = "True"
	ConditionFalse   ConditionStatus = "False"
	ConditionUnknown ConditionStatus = "Unknown"

These are valid condition statuses. "ConditionTrue" means a resource is in the condition. "ConditionFalse" means a resource is not in the condition. "ConditionUnknown" means kubernetes can't decide if a resource is in the condition or not. In the future, we could add other intermediate conditions, e.g. ConditionDegraded.
