Question

感谢您的帮助！

我有以下Dockerfile：

FROM node:slim

RUN mkdir -p /project
WORKDIR /project

# workdir is empty
RUN ls -a
COPY . /project

# workdir is full
RUN ls -a

# this command create node_modules folder on it own
RUN npm install

# I have node_modules folder with packages
RUN ls -a
RUN ls -d node_modules/*

最后的输出是：

Step 8/9 : RUN ls -a

但是当我从以下命令查看容器的文件时：

docker-compose -f docker-compose.dev.yml run project ls

我没有 node_modules 文件夹（带有依赖项的文件夹），因为它无法启动我的容器：

docker-compose -f docker-compose.dev.yml up

sh: 1: webpack-dev-server: not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! project@1.0.0 dev: `webpack-dev-server --inline --progress --config build/webpack.dev.conf.js`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the project@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?
npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2018-04-11T19_09_35_669Z-debug.log

docker-compose 很简单：

version: '3'
services:
  project:
    container_name: project
    build:
      context: .
      dockerfile: Dockerfile-dev
    command: npm run dev
    volumes:
      - .:/project
    ports:
      - 8080:8080

问题是：为什么会发生？如何解决问题？

Dockerfile中创建的数据在容器中不存在
