func SetupDynamicZipkinPublishing

func SetupDynamicZipkinPublishing(logger *zap.SugaredLogger, configMapWatcher *configmap.InformedWatcher, serviceName string) error

SetupDynamicZipkinPublishing sets up Zipkin trace publishing for the process, by watching a ConfigMap for the configuration. Note that other pieces still need to generate the traces, this just ensures that if generated, they are collected appropriately. This is normally done by using tracing.HTTPSpanMiddleware as a middleware HTTP handler. The configuration will be dynamically updated when the ConfigMap is updated.
