Types

type Config

type Config struct {
	Services map[string]map[string]*service `mapstructure:"services"`
}

Config configures a registry

func ParseConfig

func ParseConfig(m map[string]interface{}) (*Config, error)

ParseConfig translates Config file values into a Config struct for consumers.

type Node

type Node interface {
	// Address where the given node is running.
	Address() string

	// metadata is used in order to differentiate services implementations. For instance an AuthProvider Service could
	// have multiple implementations, basic, bearer ..., metadata would be used to select the Service type depending on
	// its implementation.
	Metadata() map[string]string

	// ID returns the node ID.
	ID() string
}

Node defines nodes on a service.

type Registry

type Registry interface {
	// Add registers a Service on the memoryRegistry. Repeated names is allowed, services are distinguished by their metadata.
	Add(Service) error

	// GetService retrieves a Service and all of its nodes by Service name. It returns []*Service because we can have
	// multiple versions of the same Service running alongside each others.
	GetService(string) (Service, error)
}

Registry provides with means for dynamically registering services.

type Service

type Service interface {
	Name() string
	Nodes() []Node
}

Service defines a service.
