This repository contains the source for building various versions of the Ruby application as a reproducible Docker image using source-to-image. Users can choose between RHEL and CentOS based builder images. The resulting image can be run using Docker.

For more information about using these images with OpenShift, please see the official OpenShift Documentation.

Ruby versions currently provided are:

• ruby-2.0
• ruby-2.2

RHEL versions currently supported are:

• RHEL7

CentOS versions currently supported are:

• CentOS7

A Ruby 1.9 image can be built from this third party repository. It is not maintained by Red Hat nor is part of the OpenShift project.

To build a Ruby image, choose either the CentOS or RHEL based image:

• RHEL based image

  To build a RHEL based Ruby image, you need to run the build on a properly subscribed RHEL machine.

  $ git clone https://github.com/openshift/sti-ruby.git
  $ cd sti-ruby
  $ make build TARGET=rhel7 VERSION=2.0
  

• CentOS based image

  This image is available on DockerHub. To download it run:

  $ docker pull openshift/ruby-20-centos7
  

  To build a Ruby image from scratch run:

  $ git clone https://github.com/openshift/sti-ruby.git
  $ cd sti-ruby
  $ make build VERSION=2.0
  

Notice: By omitting the VERSION parameter, the build/test action will be performed on all provided versions of Ruby.

For information about usage of Dockerfile for Ruby 2.0, see usage documentation.

For information about usage of Dockerfile for Ruby 2.2, see usage documentation.

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Ruby application built on top of the sti-ruby image.

Users can choose between testing a Ruby test application based on a RHEL or CentOS image.

• RHEL based image

  To test a RHEL7-based Ruby-2.0 image, you need to run the test on a properly subscribed RHEL machine.

  $ cd sti-ruby
  $ make test TARGET=rhel7 VERSION=2.0
  

• CentOS based image

  $ cd sti-ruby
  $ make test VERSION=2.0
  

Notice: By omitting the VERSION parameter, the build/test action will be performed on all the provided versions of Ruby.

• <ruby-version>

  Dockerfile and scripts to build container images from.

• hack/

  Folder containing scripts which are responsible for build and test actions performed by the Makefile.

1. Platform name (lowercase) - ruby
2. Platform version(without dots) - 20
3. Base builder image - centos7/rhel7

Examples: openshift/ruby-20-centos7, openshift/ruby-20-rhel7
