Functions

func MakeHostRule 

func MakeHostRule(hosts ...string) string

MakeHostRule builds a new Host() rule string to be used by traefik.

func Marshal 

func Marshal(config *Config, previous []byte) ([]byte, error)

Marshal marshals this configuration in nicely formatted form. Where possible, this will maintain yaml comments.

Previous may optionally provide the bytes of a previous configuration file to replace settings in. The previous yaml file must be a valid configuration yaml, meaning all fields should be set. When previous is of length 0, the default configuration yaml will be used instead.

func TrimSuffixFold 

func TrimSuffixFold(s string, suffix string) string

Types

type Config 

type Config struct {
	Listen ListenConfig `yaml:"listen" recurse:"true"`

	// Maximum age for backup in days
	MaxBackupAge time.Duration `yaml:"age" validate:"duration"`

	// Various components use password-based-authentication.
	// These passwords are generated automatically.
	// This variable can be used to determine their length.

}

Config represents the configuration of a WissKI Distillery.

Config is read from a byte stream using [Unmarshal].

Config contains many methods that do not require any interaction with any running components. Methods that require running components are instead store inside the [Distillery] or an appropriate [Component].
