Docker Rails Demo

This is a demo app I created show how to develop and deploy
a moderately complex application with docker.

See the Dockerfile for comments on the setup.

When doing development, use Gemfile.tip to add gems you are playing around
with, this is a Docker build optimization. Once you've decided you want to use
it, move it to the main Gemfile.

A startup script is provided in bin/startup.rb
This script takes various arguments to make it easy to start different services
within your app (e.g. Unicorn, Sidekiq).


git clone
cd docker-rails-dev-demo
docker build -t rails-demo .

# Run the tests
docker run -d --name rails-app rails-demo tests
# Start the app server (unicorn) [`server` is the default command here]
docker run -d -p 80:8080 --name rails-app rails-demo
# Start the job worker (sidekiq)
docker run -d --name rails-app rails-demo jobs
