tubbz-alt / s2i-ruby-vocab-builder

Ruby Source-to-Image builder tailored to the needs of the SDP Vocabulary project.

Ruby Docker images

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.

These images have been customized for the SDP Vocabulary service.

Versions

Ruby versions currently provided are:

• ruby-2.5

RHEL versions currently supported are:

• RHEL7

CentOS versions currently supported are:

• CentOS7

Installation

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://gitlab.mitre.org/CDC-SDP/s2i-ruby-container.git
  $ cd s2i-ruby-container
  $ make build TARGET=rhel7 VERSIONS=2.5
  

• CentOS based image

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

  $ docker pull centos/ruby-25-centos7
  

  To build a Ruby image from scratch run:

  $ git clone https://gitlab.mitre.org/CDC-SDP/s2i-ruby-container.git
  $ cd s2i-ruby-container
  $ make build TARGET=centos7 VERSIONS=2.5
  

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

Usage

For information about usage of Dockerfile for Ruby 2.5, see usage documentation.

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Ruby application built on top of the s2i-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 image, you need to run the test on a properly subscribed RHEL machine.

  $ cd s2i-ruby-container
  $ make test TARGET=rhel7 VERSIONS=2.5
  

• CentOS based image

  $ cd s2i-ruby-container
  $ make test TARGET=centos7 VERSIONS=2.5
  

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