Docker NodeJS bcrypt 错误

Question

当我尝试docker-compose up时出现以下错误

graphql_1     | Error: Error loading shared library /usr/app/node_modules/bcrypt/lib/binding/bcrypt_lib.node: Exec format error

当我从 package.json 中删除 bcrypt 模块时，docker-compose 运行没有问题。我看到一些关于堆栈溢出的帖子建议在安装后重建 bcrypt，但这并不能解决问题。

我的 dockerfile 设置如下

FROM node:10.8.0-alpine

# Whispr work directory
WORKDIR /usr/app

# Copy dependencies first for effective caching
COPY package*.json ./

RUN apk add --no-cache --virtual .build-deps alpine-sdk python \
 && npm install \
 && npm rebuild bcrypt --build-from-source \
 && apk del .build-deps

COPY . .

我的 docker-compose 文件如下

version: '3'
services:
  redis:
    image: redis:5.0-rc

  postgresql:
    image: postgres:10
    env_file:
      - postgresql.env

  graphql:
    build: .
    command: npm run start
    ports:
      - "3000:3000"
    volumes:
      - .:/usr/app
    env_file:
      - .env
    depends_on:
      - "redis"
      - "postgresql"
    links:
      - "redis"
      - "postgresql"

我终于通过在 docker-compose.yml 中添加 node_modules 的匿名卷来使其正常工作。您将在本文中找到更多详细信息:https://www.richardkotze.com/top-tips/install-bcrypt-docker-image-exclude-host-node-modules

volumes:
  - .:/usr/app # named volume
  - /usr/app/node_modules # anonymous volume for node_modules only
