Registry & Service Discovery

Registry and Service Discovery are two essential components in the context of distributed systems and microservices architecture. They play crucial roles in enabling dynamic and efficient communication between services within a distributed environment.

Registry A registry is a centralized or distributed database that stores information about available services within a network or system.

Service Discovery Service Discovery is the process by which a client or service component dynamically finds and communicates with other services within a distributed system. It involves querying a service registry or a similar mechanism to obtain information about the location and availability of required services.

The Discovery interface extend kratos.Discovery with WatchAll for gateway integration

// Discovery is service discovery.
type Discovery interface {
	registry.Discovery
	// WatchAll creates a watcher to all services
	WatchAll(ctx context.Context) (registry.Watcher, error)
}

Provider​

Etcd​

In your configuration

services:
  registry:
    type: etcd
    endpoint: http://etcd:2379 # your etcd endpoint
tip

We recommend using etcd because APIsix and DTM are already using etcd. Using other service discovery solutions may increase operational complexity.
