Functions

func ApiextensionsJsonToKyvernoConditions

func ApiextensionsJsonToKyvernoConditions(original apiextensions.JSON) (interface{}, error)

ApiextensionsJsonToKyvernoConditions takes in user-provided conditions in abstract apiextensions.JSON form and converts it into []kyverno.Condition or kyverno.AnyAllConditions according to its content. it also helps in validating the condtions as it returns an error when the conditions are provided wrongfully by the user.
