Dream

The Awesome-Docker-Development-Environment-With-Resolving-Domains-Super-Fantastic Dream Machine (for OSX)

Requirements

You must install an appropriate Docker runtime before running the bootstrap.

Visit https://www.docker.com/products/overview for more details.

Instructions

Clone and cd to this repo, then run the bootstrapper to get things going

./bootstrap.sh

This does the following:

• Add a resolver entry, pointing at the local Docker install
• Boots up two core service containers:
  • nginx-proxy for mapping host names to containers
  • dnsmasq for a simple DNS service

Usage

A container with the environment variable VIRTUAL_HOST=hello.dream will be accessible at http://hello.dream. This is due to nginx-proxy automatically proxying these virtual hosts and dnsmasq forwarding the requests on to the proxy. The resolver configuration on your host machine allows your browser/terminal to access them.

Basic example to demonstrate this:

docker run --rm -e VIRTUAL_HOST=hello.dream -p 80 tutum/hello-world

Using docker-compose you can easily set pre-configured VIRTUAL_HOST settings for your applications using the environment key:

app:
  build: .
  command: bundle exec rails s -p 3000 -b '0.0.0.0'
  volumes:
    - .:/app
  ports:
    - "3000"
  environment:
    - VIRTUAL_HOST=myapp.dream
