Dockerfile.dev: nodemon: Permission denied-CodePudding

Setting up my dev environment on Docker. I am running Nodejs v16.16.0.

I am using Nodemon and a docker volume to keep my dev work in sync with the docker container.

Dockerfile.dev

FROM node:alpine

WORKDIR /usr/src/app

COPY . .

RUN npm install

EXPOSE 3000

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

package.json

{
  "name": "docker-example-1",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node index",
    "dev": "nodemon index",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "Kane Hooper <[email protected]>",
  "license": "MIT",
  "dependencies": {
    "express": "^4.18.1"
  },
  "devDependencies": {
    "nodemon": "^2.0.19"
  }
}

I execute docker run -p 8080:3000 -v $(pwd):/usr/src/app -v /usr/src/app/node_modules --name nodeappcontainer nodeapp

I get the following error /tmp/dev6585779965.sh: line 2: nodemon: Permission denied

Any assistance on how to resolve this would be much appreciated.

CodePudding user response：

The problem resolved when I bumped the version of nodemon from 2.0.18 down to 2.0.16.

CodePudding user response：

Add the following line before the EXPOSE on your dockerfile, this will grant access for reading and writing on your .sh script

RUN ["chmod", "755","/tmp/dev6585779965.sh"]
