Question

我正在尝试借助docker compose在卷的帮助下部署create-react-app项目。我在Windows 10计算机上使用Windows的Docker。我已从项目中删除了node_modules文件夹，以便可以利用docker文件中的 RUN npm install 。但是我收到以下错误日志：

$ docker-compose up --build                                                                                             Building web

我的dockerfile.dev如下：

FROM node:alpine

ENV NPM_CONFIG_LOGLEVEL warn

WORKDIR '/app'

COPY package.json .
RUN npm install 

COPY . . 

CMD ["npm", "run", "start"]

Docker-compose.yml如下：

version : '3'
services : 
  web:  
    build: 
      context: .
      dockerfile: Dockerfile.dev
    ports: 
      - "3000:3000"
    volumes: 
      - .:/app 
      - /app/nodes_modules

请让我知道哪个步骤不正确？

Answer 1

在删除docker-compose.yml中的最后一行后尝试

- /app/nodes_modules

我认为问题是因为两个卷首先用于父级，这两个卷也将node_module用作子目录，而第二个卷则由docker本身在node_modules文件夹的某个地方创建和管理。因此，似乎node_module文件夹的卷之间存在冲突

Answer 2

我认为您的docker-compose文件中有拼写错误。 -/ app / node_modules不是-/ app / node s _modules
