I am new to Docker and I am trying to run a container following this tutorial and was running into some issues while using the --volume or -v as shown below:

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

So mine looks like this:

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

The error thrown is this:

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!   path: '/usr/app/package.json'
npm ERR! }

I have built the image without any issues:

docker build -f Dockerfile.dev .

My Dockerfile.dev looks like this:

FROM node

WORKDIR /usr/app

COPY ./package.json ./
RUN npm install

COPY . .

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

And the package.json looks like this:

{
  "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"
  }
}

From what I understand, I do not have sufficient permissions in the container to run this. This is exactly what I was following in the tutorial. What am I doing wrong and how do I fix this?

  • Use `COPY` on behalf of `node` user (look at answers here: https://stackoverflow.com/a/66818650/10438425, https://github.com/nodejs/docker-node/issues/1262#issuecomment-677577653) `COPY --chown=node:node package.json .` `RUN npm install` `COPY --chown=node:node . .` – Ivan Sidaruk Mar 26 '21 at 14:19
