func Parse ¶
func Parse(rd io.Reader) (*Configuration, error)
Parse parses an input configuration yaml document into a Configuration struct This should generally be capable of handling old configuration format versions
Environment variables may be used to override configuration parameters other than version, following the scheme below: Configuration.Abc may be replaced by the value of REGISTRY_ABC, Configuration.Abc.Xyz may be replaced by the value of REGISTRY_ABC_XYZ, and so forth

NewParser returns a *Parser with the given environment prefix which handles versioned configurations which match the given parseInfos
func (*Parser) Parse ¶
Parse reads in the given []byte and environment and writes the resulting configuration into the input v
Environment variables may be used to override configuration parameters other than version, following the scheme below: v.Abc may be replaced by the value of PREFIX_ABC, v.Abc.Xyz may be replaced by the value of PREFIX_ABC_XYZ, and so forth

func (Storage) Parameters ¶
func (storage Storage) Parameters() Parameters
Parameters returns the Parameters map for a Storage configuration
func (*Storage) UnmarshalYAML ¶
UnmarshalYAML implements the yaml.Unmarshaler interface Unmarshals a single item map into a Storage or a string into a Storage type with no parameters
type Version ¶
type Version string
Version is a major/minor version pair of the form Major.Minor Major version upgrades indicate structure or type changes Minor version upgrades should be strictly additive

Version Version
// ParseAs defines the type which a configuration file of this version
// should be parsed into

// ConversionFunc defines a method for converting the parsed configuration
// (of type ParseAs) into the current configuration version
// Note: this method signature is very unclear with the absence of generics
ConversionFunc func(interface{}) (interface{}, error)
