	AuthPerHost                  map[string]Headerer
	DockerCredentialsPerRegistry map[string]BasicCredentials
	Paths                        ConfigurablePaths
	Stage1                       Stage1Data
}

Config is a single place where configuration for rkt frontend needs resides.

func GetConfig

func GetConfig() (*Config, error)

GetConfig gets the Config instance with configuration taken from default system path (see common.DefaultSystemConfigDir) overridden with configuration from default local path (see common.DefaultLocalConfigDir).

func GetConfigFrom

func GetConfigFrom(dirs ...string) (*Config, error)

type ConfigurablePaths

type ConfigurablePaths struct {
	DataDir         string
	Stage1ImagesDir string
}

ConfigurablePaths holds various paths defined in the configuration.

type Headerer

	Header() http.Header
}

Headerer is an interface for getting additional HTTP headers to use when downloading data (images, signatures).
