is it a must that package-lock.json require root previledges??

Answer 1

Check your local path and the path you are executing the command. I faced this issue due to manual error. I was trying to run npm command from different path than the path in which package related files are present.

Please refer to this post for more details

This error is occurring because of permission error. Lets give node user permission with our app folder.

FROM node:18.6.0-alpine3.15
RUN addgroup app && adduser -S -G app app
USER app
WORKDIR /app
COPY --chown=app:node package*.json .
RUN npm install
COPY --chown=app:node . .
ENV API_URL=http://api.myapp.com/
EXPOSE 3000
# Shell form
# /bin/sh
# This command will spin a new shell and execute the command there
# CMD npm start

# Exec form
CMD ["npm", "start"]

Build the image and then run the application

docker run -d -p 4000:3000 --name yellow-lime react-app:2

Giving the node USER permission to the package.json helped me.

COPY --chown=node:node package*.json .

in your case giving the node USER permission to package-lock.json should work as shown below:

COPY --chown=user:user package-lock.json .
