Perl Docker images

This repository contains the source for building various versions of the Perl 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.

Versions

Perl versions currently provided are:

• perl-5.16
• perl-5.20

RHEL versions currently supported are:

• RHEL7

CentOS versions currently supported are:

• CentOS7

Installation

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

• RHEL based image

  To build a RHEL based perl-5.16 image, you need to run the build on a properly subscribed RHEL machine.

  $ git clone https://github.com/openshift/s2i-perl.git
  $ cd s2i-perl
  $ make build TARGET=rhel7 VERSION=5.16
  

• CentOS based image

  This image is available on DockerHub. To download perl-5.16 image, run:

  $ docker pull openshift/perl-516-centos7
  

  To build the perl-5.16 image from scratch run:

  $ git clone https://github.com/openshift/s2i-perl.git
  $ cd s2i-perl
  $ make build VERSION=5.16
  

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

Usage

For information about usage of Dockerfile for Perl 5.16, see usage documentation.

For information about usage of Dockerfile for Perl 5.20, see usage documentation.

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Perl application built on top of the s2i-perl image.

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

• RHEL based image

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

  $ cd s2i-perl
  $ make test TARGET=rhel7 VERSION=5.16
  

• CentOS based image

  $ cd s2i-perl
  $ make test VERSION=5.16
  

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

Repository organization

• <perl-version>
