docker 和不同端口上的两个服务-6ren

docker 和不同端口上的两个服务

转载作者：行者123 更新时间：2023-12-05 02:27:48

假设我想创建两个服务:

第一个在 5000 端口
第二个在 7000 端口

所以我创建 docker-compose.yml 文件

version: "3"
services:
  project-server:
    build: .
    ports:
      - "5000:5000"
    environment:
      - PORT=5000
    depends_on:
      - mongo
  project-socket-server:
    build:
      context: "."
      dockerfile: "./Dockerfile-socket"
    ports:
      - "7000:7000"
    environment:
      - PORT=7000
    depends_on:
      - project-server

  mongo:
    image: mongo
    environment:
      - MONGO_INITDB_ROOT_USERNAME=project_admin
      - MONGO_INITDB_ROOT_PASSWORD=9293
    volumes:
      - mongo-db:/data/db
volumes:
  mongo-db:

和 docker-compose.dev.yml

version: "3"
services:
  project-server:
    build:
      context: .
      args:
        NODE_ENV: development
    volumes:
      - .:/server
      - /server/node_modules
    environment:
      - NODE_ENV=development
      - MONGO_USER=project_admin
      - MONGO_PASSWORD=9293
    command: npm run dev
  project-socket-server:
    build:
      context: "."
      dockerfile: "./Dockerfile-socket"
      args:
        NODE_ENV: development
    volumes:
      - .:/server
      - /server/node_modules
    environment:
      - NODE_ENV=development
      - MONGO_USER=project_admin
      - MONGO_PASSWORD=9293
    command: npm run dev
  mongo:
    environment:
      - MONGO_INITDB_ROOT_USERNAME=project_admin
      - MONGO_INITDB_ROOT_PASSWORD=9293

Dockerfile - 用于第一个服务

FROM node:15
WORKDIR /server
COPY package.json .
RUN npm install --only=production

ARG NODE_ENV
RUN if [ "$NODE_ENV" = "development" ]; \
        then npm install; \
        else npm install --only=production; \
        fi

COPY . ./
EXPOSE 5000
CMD ["node", "index.js"]

第二个服务的 Dockerfile-socket

FROM node:15
WORKDIR /server
COPY package.json .
RUN npm install --only=production

ARG NODE_ENV
RUN if [ "$NODE_ENV" = "development" ]; \
        then npm install; \
        else npm install --only=production; \
        fi

COPY . ./
EXPOSE 7000
CMD ["node", "server.js"]

还有 package.json:

{
  "name": "project-server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "nodemon index.js && nodemon server.js",
    "dev": "nodemon index.js && nodemon server.js"
  },
  "dependencies": {
    "@socket.io/mongo-adapter": "^0.2.1",
    "cookie-parser": "^1.4.6",
    "express": "^4.18.1",
    "mongodb": "^4.6.0",
    "mongoose": "^6.3.2",
    "nodemailer": "^6.7.5",
    "socket.io": "^4.5.1",
    "stripe": "^9.11.0",
    "ws": "^8.6.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.16"
  }
}

问题是，在我调用 docker-compose 之后，两个容器都会启动 - 这里没有问题，因为我调用 localhost:5000，它给了我正确的数据，但是在我调用 localhost:7000 之后，我看到了所有数据就像我调用 localhost:5000 一样。我做错了什么吗？

更新:

看起来在端口 7000 上启动了 index.js，而不是 server.js 脚本

index.js 文件:

const port = process.env.PORT;
console.log("connected to port index " + port);

回馈:

connected to port index 5000

server.js 文件:

const port = process.env.PORT;
console.log("connected to port server " + port);

回馈:

connected to port index 7000

UPD2:

检查端口 5000:

最佳答案

根据您提供的 docker 容器 inspect 输出，您似乎正在运行以下命令:

 "Path": "docker-entrypoint.sh",
 "Args": [
   "npm",
   "run",
   "dev"
 ],

 

 "Cmd": [
   "npm",
   "run",
   "dev"
 ]

在它们中，这与您在 docker-compose.dev.yml 文件中为两个容器提供的 command 一致:

command: npm run dev

如 docker-compose documentation 中所述，请注意，这样做会覆盖您的容器 Dockerfile 命令。

这意味着两个容器都在运行 dev 脚本。

根据您的项目结构，事实证明两个容器共享相同的 package.json 和代码。

在 package.json 中，您定义了 dev 脚本，如下所示:

"scripts": {
  "start": "nodemon index.js && nodemon server.js",
  "dev": "nodemon index.js && nodemon server.js"
},

这意味着您将在两个容器 index.js 中启动，根据每个容器中的 PORT 变量声明，具有不同的端口，但它们都在运行 index.js 毕竟。

这就解释了为什么每次调用都得到相同的输出:

connected to port index ...

尽管我的建议是将每个容器的源代码分开，但要解决该问题，您可以尝试为每个容器运行不同的脚本。我的意思是，在您的 package.json 文件中，我将包含一个新脚本 server，例如:

"scripts": {
  "start": "nodemon index.js && nodemon server.js",
  "dev": "nodemon index.js",
  "server": "nodemon server.js"
},

并在 docker-compose 中启动容器时使用新脚本:

  project-socket-server:
    build:
      context: "."
      dockerfile: "./Dockerfile-socket"
      args:
        NODE_ENV: development
    volumes:
      - .:/server
      - /server/node_modules
    environment:
      - NODE_ENV=development
      - MONGO_USER=project_admin
      - MONGO_PASSWORD=9293
    command: npm run server

作为替代方案，您可以删除以下行:

command: npm run dev

从你的 docker-compose.dev.yml 文件:

ersion: "3"
services:
  project-server:
    build:
      context: .
      args:
        NODE_ENV: development
    volumes:
      - .:/server
      - /server/node_modules
    environment:
      - NODE_ENV=development
      - MONGO_USER=project_admin
      - MONGO_PASSWORD=9293
  project-socket-server:
    build:
      context: "."
      dockerfile: "./Dockerfile-socket"
      args:
        NODE_ENV: development
    volumes:
      - .:/server
      - /server/node_modules
    environment:
      - NODE_ENV=development
      - MONGO_USER=project_admin
      - MONGO_PASSWORD=9293
  mongo:
    environment:
      - MONGO_INITDB_ROOT_USERNAME=project_admin
      - MONGO_INITDB_ROOT_PASSWORD=9293

这将使 docker 使用不同 Dockerfile 中提供的 CMD:

CMD ["node", "index.js"]

和:

CMD ["node", "server.js"]

我认为它也会起作用。

正如我所说，请考虑在任何情况下重新排序您的项目结构，以避免使用相同的目录来构建您的两个应用程序，正如您所看到的那样，这可能会导致多个问题。
