Question

我是Docker的新手，我正在尝试按照this教程运行容器，并且在使用--volume或-v时遇到了一些问题，如下所示：

docker run -v <absolute path to host directory>:<absolute path to container working directory> <image id>

我的看起来像这样：

docker run -p 3000:3000 -v /usr/app/node_modules -v "$(pwd)":/usr/app 900a3497fc39

抛出的错误是这样的：

npm ERR! code EACCES
npm ERR! syscall open
npm ERR! path /usr/app/package.json
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, open '/usr/app/package.json'
npm ERR!  [Error: EACCES: permission denied, open '/usr/app/package.json'] {
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'open',
npm ERR!   path: '/usr/app/package.json'
npm ERR! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.

我构建的图像没有任何问题：

docker build -f Dockerfile.dev .

我的Dockerfile.dev看起来像这样：

FROM node

WORKDIR /usr/app

COPY ./package.json ./
RUN npm install

COPY . .

CMD [ "npm", "run", "dev" ]

package.json看起来像这样：

{
  "name": "vite-counter",
  "scripts": {
    "dev": "vite",
    "build": "vite build"
  },
  "dependencies": {
    "vue": "^3.0.0-beta.15"
  },
  "devDependencies": {
    "vite": "^1.0.0-beta.3",
    "@vue/compiler-sfc": "^3.0.0-beta.15"
  }
}

据我了解，我在容器中没有足够的权限来运行它。这正是我在本教程中遵循的内容。我在做什么错，该如何解决？

权限在Docker容器中被拒绝
