Here is the Dockerfile for my node.js project:
FROM node:14.16.0-alpine3.13
RUN addgroup app && adduser -S -G app app
RUN mkdir /app && chown app:app /app
USER app
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 80
CMD ["npm", "start"]
After giving relevant access to the app, I encountered an error when running docker-compose up on my Ubuntu 18 server:
Step 6/9 : RUN npm install

It's worth mentioning that this project works fine on my local Windows system with the same Dockerfile.
