How-To: Configure Dapr to use gRPC

How to configure Dapr to use gRPC for low-latency, high performance scenarios

Dapr 为本地调用实现 HTTP 和 gRPC API 。 gRPC is useful for low-latency, high performance scenarios and has language integration using the proto clients.

You can find a list of auto-generated clients here.

Dapr 运行时实现 服务 ，应用程序可以通过 gRPC 进行通信。

除了通过 gRPC 调用 Dapr ， Dapr 还可以通过 gRPC 与应用程序通信。 To do that, the app needs to host a gRPC server and implements the Dapr appcallback service

配置 dapr 以通过 gRPC 与应用程序通信

自托管

当在自己托管模式下运行时，使用 --app-protocol 标志告诉Dapr 使用 gRPC 来与应用程序对话：

dapr run --app-protocol grpc --app-port 5005 node app.js

This tells Dapr to communicate with your app via gRPC over port 5005.

Kubernetes

On Kubernetes, set the following annotations in your deployment YAML:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
  namespace: default
  labels:
    app: myapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
      annotations:
        dapr.io/enabled: "true"
        dapr.io/app-id: "myapp"
        dapr.io/app-protocol: "grpc"
        dapr.io/app-port: "5005"
...
