Docker nodeJS bcrypt error

I get following error when I try docker-compose up

When I delete bcrypt module from package.json, docker-compose runs without a problem. I have seen a few posts on stack overflow suggesting to rebuild bcrypt after installing but this does not solve the problem.

My dockerfile setting is below

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 . .

My docker-compose file is below

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"

I set up this on docker-compose and dockerfile, it working now dockerfile:

  • RUN apk add --no-cache make gcc g++ python3 && \ npm install && \
    npm rebuild bcrypt --build-from-source && \ apk del make gcc g++ python3 docker-compose:
  • volumes: - .:/usr/src/app - /usr/src/app/node_modules

I finally got it working by adding an anonymous volume for node_modules in my docker-compose.yml. You'll find more details in this article: 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

I have never managed to solve this in the end.

I ended up migrating the package to bcryptjs which does not require any OS specific dependencies.
