码头和两个不同港口的服务
码头和两个不同港口的服务
提问于 2022-07-07 10:12:19
假设我想创建两个服务：
- 第一个在5000端口
- 第二个在7000端口
所以我创建了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=9293Dockerfile -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 [ "$NODE_ENV" = "development" ]; \
then npm install; \
else npm install --only=production; \
fi
COPY . ./
EXPOSE 5000
CMD ["node", "index.js"]以及第二个服务的Dockerfile-套接字。
FROM node:15
WORKDIR /server
COPY package.json .
RUN npm install --only=production
ARG NODE_ENV
RUN if [ "$NODE_ENV" = "development" ]; \
then npm install; \
else npm install --only=production; \
fi
COPY . ./
EXPOSE 7000
CMD ["node", "server.js"]以及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之后--编写两个容器将启动--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，我看到了所有的数据，就好像我调用localhost:5000。我做错了什么吗？
UPD:
它看起来像是在端口7000上启动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 5000server.js文件：
const port = process.env.PORT;
console.log("connected to port server " + port);回馈：
connected to port index 7000UPD2:
检查5000端口：

根据码头容器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"
]在这两个文件中，这与您在command文件中为两个容器提供的docker-compose.dev.yml是一致的：
command: npm run dev正如docker-compose 文档中所述，请注意，这样做是在覆盖容器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，结果是两个容器共享相同的package.json和代码。
在package.json中，您定义了如下dev脚本：
"scripts": {
"start": "nodemon index.js && nodemon server.js",
"dev": "nodemon index.js && nodemon server.js"
},这意味着根据每个容器中的index.js变量声明，您将在两个容器中启动具有不同端口的PORT，但它们毕竟都在运行index.js。
这就解释了为什么每次调用都得到相同的输出：
connected to port index ...虽然我的建议是将每个容器的源代码分开，但是为了解决这个问题，您可以尝试在每个容器中运行不同的脚本。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中启动容器时使用新脚本-撰写：
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作为另一种选择，您可以删除这些行：
command: npm run dev从您的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这将使停靠者使用在不同的CMD s中提供的Dockerfile：
CMD ["node", "index.js"]以及：
CMD ["node", "server.js"]我认为它也会起作用。
正如我所说的，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，因为您可以看到这可能是几个问题的原因。

正如"将您的NodeJS应用程序放入码头容器中“中提到的
EXPOSE与其他指令有些不同，因为它没有实际用途。 它仅用于提供关于容器希望公开哪个端口的元数据。 您不需要在容器中使用公开，但是任何必须了解如何连接到它的人都会欣赏它。
您需要检查CMD ["node", "server.js"]在Dockerfile-socket中是否在运行时利用了project-socket-server服务environment: PORT=7000。
它使用socketio/socket.io-mongo-adapter，可以使用它所适应的现有MongoDB的端口。
正如与“任择议定书”讨论和详细的杰坎帕内罗的更精确的回答一样，根本原因是公共的package.json，公共开发指令首先是index.js (首先)，然后是server.js。
第一个(index.js)将回答查询，即使它在服务器容器中。
