How to build Node.js Application with Docker | Node.js with Docker

In this video we will learn about building a docker container for existing nodejs app. We will use alpine Linux image and copy the source code to alpine Linux and build a new docker image

===========================

===============================

FROM alpine:latest
RUN apk add --no-cache nodejs npm

WORKDIR /app

COPY . /app

RUN npm install

EXPOSE 9005

ENTRYPOINT ["node"]

All the other tutes for basic web app containerization I watched, or read, were either way to complex (going off the deep end into *really* long Dockerfiles) or way too simple (only demoing spinning up existing images from Docker's repo). This tute was exactly what I needed to help me understand the basics of making my own images. Thanks!

docker compose with shared volumes between dev and container asking with docker sync allow to do auto reload inside container when source code files changed by programmer outside the container.

Nice explanation. I do not understand how npm install runs on docker but not on your physical machine

Great video. Two details: if a container was daemonized, then I believe you need to use docker stop or docker kill; Also, I noticed when you typed docker images, it shows old versions?? of built dockers (ie IMAGE ID: 14926fb80dde). Do you use docker prune to get rid of them?

[prajwalpatil]

if I want to use the mongodb then Do I have to install it in docker container ?

'ctrl + C' not exiting the docker run, how to exit docker run

[vishnutechbuddy]

How can we run the MERN App in docker container? Because Node and React runs on a separate port.
