docker.compose.yml

Question

从昨天开始，我正尝试将以下内容一起进行dockerize，因为我使用了docker-compose 其中包含以下定义：

docker.compose.yml

version: '3'
networks:
  network:
    driver: bridge
services:
  server:
    container_name: truckpeserver
    restart: always
    build: .
    networks:
      - network
    links:
      - redis
    ports:
      - '3000:3000'
  redis:
    container_name: "redisserver"
    image: redis:latest
    networks:
      - network
    restart: always
    command: ["redis-server", "--bind", "redis", "--port", "6379"]
  prisma:
    image: prismagraphql/prisma:1.34
    restart: always
    ports:
      - '4466:4466'
    networks:
      - network
    environment:
      PRISMA_ENDPOINT: http://prisma:4466/
      PRISMA_CONFIG: |
        port: 4466
        databases:
          default:
            connector: mysql
            host: mysql
            port: 3306
            user: root
            password: prisma
  mysql:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: prisma
    volumes:
      - mysql:/var/lib/mysql
volumes:
  mysql: ~

和用于运行我的graphql服务器的dockerfile如下：

# install node.js
FROM node:10.15.3

# create necessary directories and
# permissions
RUN mkdir -p /home/node/truckpeserver/node_modules && chown -R node:node /home/node/truckpeserver

# switch to working directory
WORKDIR /home/node/truckpeserver

# copy package.json files in directory
COPY package*.json ./

# check and switch to node user.
USER node

# install node_modules.
RUN npm install

# remove duplicate packages
RUN npm dedupe

# copy project files.
COPY --chown=node:node . .

# build server
RUN npm run build

# start server
CMD ["npm", "start"]

问题：

除棱镜外，一切正常。当我每个执行代码的查询棱镜时，我都收到如下错误：

错误

truckpeserver | FetchError: request to http://localhost:4466/ failed, reason: connect ECONNREFUSED 127.0.0.1:4466

我已经尝试过的东西。

删除将与网络相关的任何其他配置链接为docker-compose会解决这个问题。在服务之间的通信中，您可以使用容器名称来进行从一个容器到另一个容器的某些调用。

现在该错误来自您的truckpeserver容器，

truckpeserver | FetchError: request to http://localhost:4466/ failed, reason: connect ECONNREFUSED 127.0.0.1:4466

您需要将localhost更改为prisma:4466。当您在某个容器中使用本地主机时，它将指向该容器的本地主机，则无法使用本地主机访问其他容器。

从错误日志来看，您似乎正在使用交叉获取？然后您可以尝试

fetch('//prisma:4466')
  .then(res => {
    if (res.status >= 400) {
      throw new Error("Bad response from server");
    }
    return res.json();
  })
....

Prisma无法从另一个Docker容器连接localhost：4466

docker.compose.yml
