Docker

Question

我在 docker 桌面的 docker 容器日志中收到此错误。

我运行这个命令在vs代码的终端 docker compose up

这是错误：

> tracking-system@1.0.0 dev /usr/src/server

> nodemon -r esm -L server.js


[nodemon] 2.0.7

[nodemon] to restart at any time, enter `rs`

[nodemon] watching path(s): *.*

[nodemon] watching extensions: js,mjs,json

[nodemon] starting `node -r esm server.js server.js`

[nodemon] app crashed - waiting for file changes before starting...


Error: Cannot find module '/usr/src/server/server.js'

at internal/main/run_main_module.js:17:47 {

code: 'MODULE_NOT_FOUND',

}

这是我项目中的所有文件

app (folder)
node_modules (folder)
.dockerignore
.gitignore
Dockerfile
Dockerfile.prod
package.json
package-lock.json
server.js

这是我的代码：

server.js:

import express from 'express';
import mongoose from 'mongoose';
import cors from 'cors';
import passport from 'passport';
import morgan from 'morgan';
import socketio from 'socket.io';

import { db_connection } from './app/config';

const app = express();
const server = http.createServer(app);
const io = socketio(server);
const PORT = process.env.SERVER_PORT || 8861;

var corsOptions = {
    origin: '*',
    optionsSuccessStatus: 200, // some legacy browsers (IE11, various SmartTVs) choke on 204
    credentials: true,
};

app.use(cors(corsOptions));
app.use(express.json());
app.use(passport.initialize());
app.use(morgan('dev'));

import passport_init from './app/middleware/passport';
import userRoute from './app/routes/user.route';
import authRoute from './app/routes/auth.route';
passport_init(passport);
app.use('/api/users', userRoute);
app.use('/api/auth', authRoute);

const startDatabase = async () => {
    try {
        await mongoose.connect(db_connection, {
            useNewUrlParser: true,
            useFindAndModify: true,
            useUnifiedTopology: true,
            useFindAndModify: false,
            dbName: 'tracking-system',
        });

        success({
            message: `Successfully connected with the database on ${db_connection}`,
            badge: true,
        });
    } catch (err) {
        error({
            message: `Unable to connected with the database ${err}`,
            badge: true,
        });
        setTimeout(startDatabase, 5000);
    }
};

startDatabase();

server.listen(PORT, () => {
    success({ message: `Server started on PORT ${PORT}`, badge: true });
});

io.on('connection', socket => {
    console.log(`Connected: ${socket.id}`)

    socket.on('disconnect', () => {
        console.log(`Disconnected: ${socket.id}`)
    })

    socket.on('update-worksheet', function () {
        io.sockets.emit('update-landing-page')
    })
})

Answer 1

在您的 Dockerfile 的第 3 行中，您只复制了项目的 package.json，但从未复制应用的源代码。

FROM node:lts-buster
WORKDIR /project/server
COPY ./server/package*.json ./
RUN npm install
COPY ./.env ../.env
CMD ["npm", "run", "dev"]

因此，您可以尝试使用此 Dockerfile（我更改了工作目录，现在它复制了所有源代码）：

FROM node:lts-buster
WORKDIR /usr/src/server
COPY . .
RUN npm install
CMD ["npm", "run", "dev"]
