Types

type Registry

type Registry struct {
	// contains filtered or unexported fields
}

A Registry represents a complete instance of the registry. TODO(aaronl): It might make sense for Registry to become an interface.

func NewRegistry

func NewRegistry(ctx context.Context, config *configuration.Configuration) (*Registry, error)

NewRegistry creates a new registry from a context and configuration struct.

func (*Registry) ListenAndServe

func (registry *Registry) ListenAndServe() error

ListenAndServe runs the registry's HTTP server.
