	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)

type ConfigurablePaths

type ConfigurablePaths struct {
	DataDir         string
	Stage1ImagesDir string
}

ConfigurablePaths holds various paths defined in the configuration.

type Headerer

type Headerer interface {
	GetHeader() http.Header
	SignRequest(r *http.Request) *http.Request
}
