Apache Dubbo binding spec
Detailed documentation on the Apache Dubbo binding component
Component format
To set up an Apache Dubbo binding, create a component of type bindings.dubbo. See this guide on how to create and apply a binding configuration.
apiVersion: dapr.io/v1alpha1 kind: Component metadata: name: <NAME> spec: type: bindings.dubbo version: v1 metadata: - name: interfaceName value: "com.example.UserService" - name: methodName value: "getUser" # Optional - name: version value: "1.0.0" - name: group value: "mygroup" - name: providerHostname value: "localhost" - name: providerPort value: "8080" Note
The Dubbo binding does not require authentication or secret configuration by default. However, if your Dubbo deployment requires secure communication, you can integrate Dapr’s secret store for sensitive values.Spec metadata fields
