Dockerfile.erb
Allows you to have simple Dockerfile.erb (embedded Ruby) templates.
Install
With rubygems you can gem install derb or directly use the script in bin/derb.
Usage
In a directory with a Dockerfile.erb run:
$ derb
It will create the Dockerfile for you. See janlelis/ruby-only for an example.
Data
You can define a Dockerfile.yml in the same directory - its data will be available in the template.
