unix - Docker 构建镜像 - glob 错误 { 错误 : EPERM: operation not permitted, scandir

Question

我正在尝试构建使用 Webpack 2.0 构建的 React+TypeScript+NodeJS 应用程序的 Docker 镜像，但出现以下错误

> frontend@0.0.1 build /
> webpack -p --config configs/webpack.config.ts --env.build --env.sourceMap

{ isDev: false }
glob error { Error: EPERM: operation not permitted, scandir '/proc/1/map_files/55836c87b000-55836c897000'
  errno: -1,
  code: 'EPERM',
  syscall: 'scandir',
  path: '/proc/1/map_files/55836c87b000-55836c897000' }
Error: EPERM: operation not permitted, scandir '/proc/1/map_files/55836c87b000-55836c897000'

运行以下命令后

docker build -t frontend .

我的 Dockerfile 看起来像这样

FROM node:latest

COPY package.json package.json
COPY npm-shrinkwrap.json npm-shrinkwrap.json
RUN npm install --production
COPY . .
EXPOSE 8080

RUN npm run deploy

最后我有了一个 .dockerignore

Dockerfile
.dockerignore
.gitignore
README.md
build
node_modules

据我所知，这是一个权限问题。我可以做些什么来更改权限吗？我什至不确定哪个过程失败了。

Answer 1

map_files 目录表示进程当前拥有由内核映射的内存的文件。此信息也包含在同一目录中的 maps 文件中。

由于这些文件是内存的表示，因此它们经常更改。如果进程创建目录列表，然后处理该列表，则当进程访问这些文件时，这些文件可能不存在。

如果构建报告 /proc 中的文件，则搜索可能从容器中的 / 目录开始，并递归搜索文件系统上的所有内容。

使用 / 以外的目录作为 Dockerfile 中的 WORKDIR

FROM node:latest

WORKDIR /app
COPY package.json npm-shrinkwrap.json /app/
RUN npm install --production
COPY . /app/
EXPOSE 8080

RUN npm run deploy
