node.js - docker-compose up --build 找不到模块

问题描述

当我启动我的容器（节点 Web 应用程序）时，docker build 很好，但是当我运行我的容器时，会出现这个问题

问题：

root@DESKTOP-PP3RIAT:/home/daramog/ezops-test-matheus-morozetti# docker-compose up
Recreating ezops-test-matheus-morozetti_web_1 ... done

我的 Dockerfile：

FROM node:alpine as builder

WORKDIR '/src'

COPY package*.json ./
RUN npm set strict-ssl false
RUN npm install


COPY . ..
RUN node ./server.js

EXPOSE 8080

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

我的 dockerfile.dev

FROM node:alpine

WORkDIR /src

COPY ["package.json","package-lock.json","/"]
RUN npm install

COPY . .

CMD ["npm", "start"]

      context: .
      dockerfile: Dockerfile
    ports:
      - "3001:3001"
    volumes:
      - .:/src
    command: ["node", "server.js"]

解决方案

该文件是否存在于容器中？

错误：找不到模块“/app/server.js”

从您的 docker-compose 我看到您将 workdir 设置为 /src，然后您将该文件复制到 /src 但是您尝试运行的是在 /app 下寻找 server.js
