Installing Docker on Windows

Follow the basic setup as in the Docker website. For me I had to download the Docker toolchain from here 🔗.

After that you should have docker installed and the Docker terminal ready to be opened from your desktop.

I followed the instructions from here https://nodejs.org/en/docs/guides/nodejs-docker-webapp/ to create my first Docker container with Node.js. Here's the short and sweet if you want just to copy and paste to see if it works: NOTE! On Windows or MacOS machines you cannot go straight to the localhost:49160 to see the app working. As explained here moby/moby#15740 they cannot run the Docker container natively so the port is actually the one on the VirtualBox so for me worked just write docker-machine ip default and whatever the ip from that is your container's ip. (my app was on http://192.168.99.100:49160/)

// app.js
const express = require('express');
const app = express();

const port = 8080;

app.get('', (req, res) => {
  res.send('Hello world! :D');
})

app.listen(port, err => {
  if (err) console.log(err)
  else console.log('App is listening on port ' + port);
})

// package.json
{
  "name": "docker-test",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.15.2"
  }
}

// Dockerfile
FROM node:boron

# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install app dependencies
COPY package.json /usr/src/app/
RUN npm install

# Bundle app source
COPY . /usr/src/app

EXPOSE 8080
CMD [ "npm", "start" ]

Then after you have created those files to a folder inside there run these with your Docker terminal:

docker build -t YOUR_USER_NAME/node-web-app .
docker run -p 49160:8080 -d YOUR_USER_NAME/node-web-app

And that should be it! Look and behold your app should be running (probably on http://192.168.99.100:49160/)
