Configuration Guide

Sponge natively supports the DTM driver and is compatible with mainstream service discovery components:

Supported Service Registries:

• Consul
• Etcd
• Nacos

Configuration Example (using Etcd for a gRPC service):

app:
  registryDiscoveryType: "etcd"          # Registry and discovery type: consul, etcd, nacos. If empty, disables registry and discovery.

grpcClient:
  - name: "dtmservice"                   # DTM service name
    registryDiscoveryType: "etcd"        # Registry and discovery type: consul, etcd, nacos. If empty, this field is ignored if registry and discovery are enabled.
    host: "127.0.0.1"                    # DTM service IP or domain name. If registry and discovery are enabled, this field is ignored.
    port: 36790                          # DTM service gRPC port. If registry and discovery are enabled, this field is ignored.

etcd:
  addrs: ["127.0.0.1:2379"]
