Simple Vagrant plus Node.js in a Docker container example

Inspired by Seanmatthews/vagrant-docker-osx-nodejs-server

Usage

• Make sure you have Vagrant and Docker (Stable) installed

• Clone the repo:

git clone https://github.com/megothub/vagrant-docker-osx-nodejs-server.git
cd vagrant-docker-osx-nodejs-server

• Start everything with:

vagrant up

You can check that server is running using either curl

curl http://localhost:3000

or simply point your web-browser to:

localhost:3000

Use the following command to connect to the container:

vagrant docker-exec -it -- /bin/bash

Tested with the following software

• macOS Catalina: 10.15.3
• Vagrant: 2.2.7
• Docker Desktop: 2.2.0.3 (42716)
• Docker Engine: 19.03.5
• Node.js: 12.16.1

Vagrantfile

Vagrant machine definition. Docker in our case.

Dockerfile

Contains instructions to build Docker image. Docker updates Ubuntu repos and system files, installs Node.js, creates a public www directory and moves out Node.js app to it. Then instructions tell Docker to run the app and expose one network port outside the container.

app.js

Simple Node.js server. It responds to everything with 'Hello World'. Listens on '0.0.0.0' within the container.
