How to create Docker image of ubuntu for node.js application - node.js

Question

I am new to docker build feature. I am trying to create docker image for my node.js application, however I am facing issue.
1) It shows image is create but when I am trying to docker run its give error like
"module.js:550
throw err;
^
Error: Cannot find module '
I think there is some issue with my docker file. Which I have created but I didn't get what exactly issue is
my Dockerfile
FROM ubuntu:16.04
RUN apt-get update -y
RUN apt-get install g++ -y
RUN apt install curl -y
RUN curl --silent --location https://deb.nodesource.com/setup_8.x — Node.js 8 LTS "Carbon" | bash -
RUN apt-get install --yes nodejs
RUN apt-get install --yes build-essential
# check the path
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 9012
CMD ["node", "app.js"]
Also see the my package.json for more info. of modules.

Why You make nodejs image from ubuntu when there are already official ones.
I see issue - You've overengineered You Dockerfile with unnecessary steps.
Fix Your Dockerfile and try again:
FROM node:8-alpine3.9
RUN apk update
RUN apk add --no-cache g++ make python python-dev
RUN rm -rf /var/cache/apk/*
WORKDIR /app
COPY package*.json ./
RUN npm i
COPY . .
EXPOSE 9012
CMD node app.js
From last collaboration I found that it was a typo in code where You required file from not existing folder.
"module.js:550 throw err; ^ Error: Cannot find module '../dFarmUserService/controllers/ClientRegisterController'
So fixed it together :)
