Tutorial. Getting Started

Sample Application

For the rest of this tutorial, we will be working with a simple todo list manager that is running in Node.js. If you’re not familiar with Node.js, don’t worry. No real JavaScript experience is needed.

Node.js Docker Tutorial

The Node.js getting started guide teaches you how to create a containerized Node.js application using Docker. In this guide, you’ll learn how to:

Create a simple Node.js application
Create a new Dockerfile which contains instructions required to build a Node.js image
Run the newly built image as a container
Set up a local development environment to connect a database to the container
Use Docker Compose to run the Node.js application
Configure a CI/CD pipeline for your application using GitHub Actions.
After completing the Node.js getting started modules, you should be able to containerize your own Node.js application based on the examples and instructions provided in this guide.

Using Jekyll with Docker

Compile a Jekyll project without installing Jekyll or Ruby by using Docker

File docker-compose.yml:

version: '3'

services:
  site:
    image: jekyll/jekyll:3.8.6
    command: bundle exec jekyll serve --future --incremental --watch --livereload --drafts --host 0.0.0.0 --port 4000 
    ports:
      - 4000:4000
    volumes:
      - .:/srv/jekyll
      - ./vendor/bundle:/usr/local/bundle

En el Rakefile:

task :docker do
  # sh 'docker run --rm --volume="$PWD:/srv/jekyll" --volume="$PWD/vendor/bundle:/usr/local/bundle" --env JEKYLL_ENV=development -p 4000:4000 jekyll/jekyll:3.8 jekyll serve'
  sh 'docker compose up' 
end

o bien:

➜  apuntes git:(main) ✗ cat jekyll-up 
#!/bin/bash
docker compose up                                                                                      
➜  apuntes git:(main) ✗ cat jekyll-down 
#!/bin/bash
docker compose down
