Add graceful error handling to politely decline to set a value, such as a pod label or image name that would cause the value to exceed the maximum configured length. Make the maximum configured length seta blue in the magnum configuration file. Allow different maximum lengths to be applied to different fields of each object. Use sensible defaults for these values that are known to work with a standard MySQL backing store.
