错误：/ng-app/node_modules/bcrypt/lib/binding/bcrypt_lib.node：无效的ELF标头

Question

我有一个使用Node.js的API项目的Dockerfile-Express.js

api.dockerfile

FROM node:8.9.4

COPY package.json ./

RUN npm set progress=false && npm config set depth 0 && npm cache clean --force

## Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm i && npm install nodemon --save \
    && npm install pm2 -g \
    && npm install -g sequelize-cli \
    && mkdir /ng-app \
    && chown -R node:node /ng-app \
    && cp -R ./node_modules ./ng-app

USER node

WORKDIR /ng-app

COPY . .
RUN mv docker.env .env

# Migration
RUN sequelize db:migrate
RUN sequelize db:seed:all

CMD ["pm2-runtime", "index.js"]

---

泊坞窗，compose.yaml

version: "2"
services:
  iproject-api:
    build:
      context: ./api
      dockerfile: api.dockerfile
    image: 'iproject-api'
    ports:
      - '3002:3002'
  iproject-web:
    build:
      context: ./web
      dockerfile: web.dockerfile
    image: 'iproject-web:latest'
    ports:
      - '8080:8080'
    links:
      - iproject-api

---

这是结果，我得到了

这主要是猜测。 但是您的步骤7将当前上下文中的所有文件复制到/ng-app （包括您可能拥有的任何node_modules文件夹）。 如果此node_modules文件夹包含二进制文件并且它们已安装在macOS或Windows上，则它们将是容器（即Linux）的错误体系结构。

针对此特定情况的简单解决方案是通过将node_modules文件夹添加到您的.dockerignore文件（ https://docs.docker.com/engine/reference/builder/#dockerignore-file ）中来排除它。 这样可以防止将node_modules复制到生成的容器中，而将使用步骤4的npm install中的node_modules 。
