Contributing Backends

As you can see by either the Consul or etcd source files, writing a new registry backend is easy. Just follow the example set by those two. It boils down to writing an object that implements this interface:

    type RegistryAdapter interface {
        Ping() error
        Register(service *Service) error
        Deregister(service *Service) error
        Refresh(service *Service) error

The Service struct looks like this:

type Service struct {
    ID    string
    Name  string
    Port  int
    IP    string
    Tags  []string
    Attrs map[string]string
    TTL   int

Then add a factory which accepts a uri and returns the registry adapter, and register that factory with the bridge like bridge.Register(new(Factory), "<backend_name>").
