如何在docker容器中使用nestjs运行gRPC微服务

FROM node:14-alpine

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 3000

CMD ["npm", "run", "start:prod"]

version: '3'
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - '3000:3000'
    depends_on:
      - grpc-server
  grpc-server:
    build:
      context: ./grpc-server
      dockerfile: Dockerfile
    ports:
      - '50051:50051'

FROM node:14-alpine

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 50051

CMD ["npm", "run", "start:prod"]

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { grpcOptions } from './grpc.options';

async function bootstrap() {
  const app = await NestFactory.createMicroservice(AppModule, grpcOptions);
  await app.listenAsync();
}
bootstrap();

"scripts": {
  "start:prod": "node dist/main"
}

docker-compose up --build
