不能用文件替换到目录/var/lib/docker/overlay2/if2ip5okvavl8u6jpdtpczuog/merged/app/node_modules/@ampproject/remapping

Question

在我的Windows机器上，我试图使用以下Dockerfile构建一个容器化的node.js应用程序：

  # use latest version of nodejs
  FROM node:lts-alpine
  
  # install aurelia-cli to build the app & http-server to serve static contents
  RUN npm i -g http-server
  RUN npm i -g aurelia-cli
  
  # set working directory to app
  # henceforth all commands will run inside this folder
  WORKDIR /app
  
  # copy package.json related files first and install all required dependencies
  COPY package*.json ./
  RUN npm install
  
  # copy the rest of the files and folders & install dependencies
  COPY . ./
  RUN npm run build
  
  # by default http-server will serve contents on port 8080
  # so we expose this port to host machine
  EXPOSE 8080
  
  CMD [ "http-server" , "dist" ]

但是，docker build .在行Copy . ./上失败。带着消息cannot replace to directory /var/lib/docker/overlay2/if2ip5okvavl8u6jpdtpczuog/merged/app/node_modules/@ampproject/remapping with file。

要构建容器映像，我需要做些什么？

将node_modules添加到与您的Dockerfile相同的目录中的.dockerignore文件，如概述的这里：(h/t 戴维·麦子)。

不那么优雅，只需删除项目的node_modules目录，然后重新运行docker build。
