This namely involved importing new libraries and using the new Clientset. Changes worth mentioning: * The new kubernetes library doesn't provide StoreToLister wrappers, so now I am going the casting directly. * Deleting the pods and getting their logs is done in a cleaner way (using the Clientset instead of the lower-level RESTclient).
