無法用文件替換到目錄 /var/lib/docker/overlay2/if2ip5okvavl8u6jpdtpczuog/merged/app/node_modules/@ampproject/remapping

Question

在我的 Windows 機器上，我正在嘗試使用以下 Dockerfile 構建容器化的 node.js 應用程序：

  # 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Copy . ./ Copy . ./ . 消息cannot replace to directory /var/lib/docker/overlay2/if2ip5okvavl8u6jpdtpczuog/merged/app/node_modules/@ampproject/remapping with file 。

我需要做什么來構建我的容器映像？

將node_modules添加到與 Dockerfile 位於同一目錄中的.dockerignore文件中，如下所述：(h/t David Maze )。

不太優雅，只需刪除項目的node_modules目錄，然后重新運行 docker docker build 。
