}

func (*ConfigFetcher) RenderConfig

func (f *ConfigFetcher) RenderConfig(cfg types.Config) (types.Config, error)

RenderConfig evaluates "ignition.config.replace" and "ignition.config.merge" in the given config and returns the result. If "ignition.config.replace" is set, the referenced and evaluted config will be returned. Otherwise, if "ignition.config.merge" is set, each of the referenced configs will be evaluated and merged into the provided config. If neither option is set, the provided config will be returned unmodified. An updated fetcher will be returned with any new timeouts set.

	ConfigCache    string
	FetchTimeout   time.Duration
	Logger         *log.Logger
