Node-Docker-Vagrant sample

Samples for creating web-project environment with Node.js, Docker and Vagrant

Note: At current moment I would prefer docker-compose to Vagrant, it provides much more convenient integration. See node-docker-compose-sample

What's it about

Repo represents a sample of creating web-based applicaion environment, which will allow you to implement and raise any infrastructure without manually installing service components.

Two differen usage patterns can be proposed for start:

• Virtualizing environment only, running Node process from host system
• Virtualizing whole application, including Node

First pattern can be used for standand developing procedure - your dependencies virtualized, but application process itself can be easily managed of demand. This prevents you from "create docker image" step, when you update code.

Second pattern can be used to implement multi-instance environment, like sharded application with many workers and/or processes with different roles. You can implement real production-like infrastructure to check your code in compilated conditions

OS X How-To

Fact that OS X is not a Linux has some impact on usage of Docker and integrating it with Vagrant. In case of using Linux everything should be a bit easier.

Installation

VirtualBox

See detailed guide at https://www.virtualbox.org/

Docker

While any Linux can install docker without extra pain, OS X is not originally a Linux, and it's kernel is not compatible with docker. So we have to run docker-server in VM. There is generic VirtualBox-based solution, called boot2docker

Detailed guide about launching docker at OS X I used to progress: http://viget.com/extend/how-to-use-docker-on-os-x-the-missing-guide

Vagrant

Running things up

Dockerize your project

• Create Dockerfile
• Build docker image
• Push docker image to repo (hope you registered it?)
• Try running image with exposing ports

Joining docker with vagrant

• Create Vagrantfile (you can start with vagrant init command)
