Simple Node Application

# Alpine is light-weight
FROM node:16-alpine
COPY . .
RUN npm install
CMD ["npm", "start"]

Ubuntu Application Running Node

If you need to use linux commands or install certain packages like puppeteer, using Ubuntu with Node.js installed is a better option.

# Support for many frameworks
FROM ubuntu:latest
RUN apt-get update -y
RUN apt-get upgrade -y

# <Install Node & NPM
RUN apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash
RUN apt-get install -y nodejs

# Fixing NPM to work
RUN npm i -g npm@latest
RUN npm i -g node-gyp
# />

WORKDIR /home/app
COPY . .

RUN npm i
# Makes sure node is running in production mode
RUN export NODE_ENV=production

# RUN cd dist
CMD ["npm", "start"]
