Question

我在单独的容器中提供以下服务，如您在docker-composer.yml文件中所看到的。我无法将一项服务链接到另一项服务。我正在尝试在网桥的gms-api-gateway中访问服务，该服务基于在端口7100上公开的节点构建。但是连接被拒绝了。

docker-compose.yml


version: '3'

services:
  gms-api-gateway:
    restart: always
    links:
      - gms-customers
    networks:
      - backend
    build:
      dockerfile: Dockerfile.dev
      context: ./gms-api-gateway
    depends_on:
      - gms-customers
    ports:
      - 7000:7000
    volumes:
      - './gms-api-gateway:/opt/app'
    environment:
      # - NODE_ENV=localhost
      - NODE_PORT=7000
      - NODE_HOST=http://localhost
      - GMS_CUSTOMERS_NODE_HOST=http://gms-customers:7100
  gms-customers:
    restart: always
    networks:
      - backend
    build:
      dockerfile: Dockerfile.dev
      context: ./gms-customers
    depends_on:
      - customers-db
    ports:
      - 7100:7100
    volumes:
      - './gms-customers:/opt/app'
    environment:
      - NODE_ENV=localhost
      - NODE_PORT=7100
      - CUSTOMER_DB_URI=postgres://postgres:password@customers-db/customersdb

  customers-db:
    environment:
      - POSTGRES_PASSWORD=password
      - POSTGRES_USER=postgres
      - POSTGRES_DB=customersdb
    image: 'postgres:12'
    ports:
      - '0.0.0.0:5433:5432'

networks:
  backend:
    driver: 'bridge'

gms-api-gateway

import 'reflect-metadata';
import {ApolloServer} from 'apollo-server';
import {ApolloGateway} from '@apollo/gateway';

const port = process.env.NODE_PORT || 7000;
const gateway = new ApolloGateway({
  serviceList: [
    {
      name: 'customers',
      url: `${process.env.GMS_CUSTOMERS_NODE_HOST}/graphql`
    }
  ],

  // Experimental: Enabling this enables the query plan view in Playground.
  __exposeQueryPlanExperimental: false
});

(async () => {
  const {schema, executor} = await gateway.load();
  const server = new ApolloServer({
    schema,
    executor
  });

  server.listen(port, (): void =>
    console.log(
      `API Gateway is now running on ${process.env.NODE_HOST}:${port}/graphql`
    )
  );
})();

现在，服务gms-api-gateway试图从另一个名为gms-customers的服务访问graphql模式。但是在日志中，我收到了

Encountered error when loading customers at http://gms-customers:7100/graphql: request to http://gms-customers:7100/graphql failed, reason: connect ECONNREFUSED 172.18.0.2:7100

两个服务都在同一网络上。在gms-api-gateway ping gms-customers内部有效！有人遇到过同样的问题吗？
