Gem Version

Generate Dockerfile for Ruby or Rails, Sinatra.

Dockerfile to prepare ruby is almost common, so generate its common parts. This is still experimetal and under heavy construction.

Installation

$ gem install rbdock

Usage

Create Dockerfile to build ruby

Create Dockerfile to build ruby 2.1.0 ready image.

$ rbdock 2.1.0

It generates this Dockerfile.

You can create Dockerfile to build multiple versions of ruby by rbenv or rvm.

$ rbdock 2.0.0-p353 1.9.3-p484 -i centos

It generates this Dockerfile.

Create Dockerfile for rails/sinatra application

For example, you can work with rails application developed on local environment.

$ rails new my_rails_app
$ rbdock 2.1.0 --app my_rails_app --rbenv
$ docker build -t tcnksm/rails_app .
$ docker run -i -p 3000:3000 -t tcnksm/rails_app 'rails server'

It generates this Dockerfile.

You can work with application hosted on remote repository. For example, this is my sinatra application hosted on github.

$ rbdock 2.0.0-p353 --app https://github.com/tcnksm/trying-space
$ docker build -t tcnksm/sinatra_app .
$ docker run -i -p 8080:8080 -t tcnksm/my_sinatra_app 'rackup -p 8080'

It generates this Dockerfile. Your application will be cloned to local directory (.rbdock_app) and ADD to docker image.
