Goal:

To create a tiny node J.S. web application, wrap it inside of a docker container and then be able to access that web application from a browser running on your local machine.

Steps:

  1. Create Node JS Web App
  2. Create a Dockerfile
  3. Build image from Dockerfile
  4. Run image as Container
  5. Connect to web app from browser

1. Create Node JS App

  • First create package.json and index.js
  • To install the node dependencies, run npm install
  • To start the server, run npm start or node index.js

2. Create a Dockerfile

  • Template
    1. Specify Base Image: FROM alpine
    2. Run some commands to install additional programs: RUN npm install
    3. Specify a command to run on container startup: CMD ["npm","start"]

3. Build image from Dockerfile

  • To build the image, use docker build .

4. Run image as Container

  • docker run vidya25/simpleweb

5. Connect to web app from browser

  • Port Mapping: docker run -p 8080:8080 vidya25/simpleweb
