s2i-perl-container 5.26: , s2i-perl-container 5.30:

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

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

For more information about contributing, see the Contribution Guidelines. For more information about concepts used in these container images, see the Landing page.

Perl versions currently provided:

• perl-5.30
• perl-5.26

RHEL versions currently supported:

• RHEL7
• RHEL8

CentOS versions currently supported:

• CentOS7

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

• RHEL based image

  These images are available in the Red Hat Container Catalog. To download it run:

  $ podman pull registry.access.redhat.com/rhscl/perl-530-rhel7
  

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

  $ git clone --recursive https://github.com/sclorg/s2i-perl-container.git
  $ cd s2i-perl-container
  $ make build TARGET=rhel7 VERSIONS=5.30
  

• CentOS based image

  This image is available on DockerHub. To download the perl-5.30 image, run:

  $ podman pull docker.io/centos7/perl-530-centos7
  

  To build the perl-5.30 image from scratch run:

  $ git clone --recursive https://github.com/sclorg/s2i-perl-container.git
  $ cd s2i-perl-container
  $ make build TARGET=centos7 VERSIONS=5.30
  

Note: while the installation steps are calling podman, you can replace any such calls by docker with the same arguments.

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

For information about usage of the Dockerfile for Perl 5.30, see usage documentation.

For information about usage of the Dockerfile for Perl 5.30 - mod_fcgid version, see usage documentation.

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-container
  $ make test TARGET=rhel7 VERSIONS=5.30
  

• CentOS based image

  $ cd s2i-perl-container
  $ make test TARGET=centos7 VERSIONS=5.30
  

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

• <perl-version>

  • Dockerfile

    CentOS based Dockerfile.

  • Dockerfile.rhel7

    RHEL based Dockerfile. In order to perform build or test actions on this Dockerfile you need to run the action on a properly subscribed RHEL machine.

  • s2i/bin/

    This folder contains scripts that are run by S2I:

    • assemble

      Used to install the sources into a location where the application will be run and prepare the application for deployment (eg. installing modules, etc.). In order to install application dependencies, the application must contain a cpanfile file, in which the user specifies the modules and their versions. An example of a cpanfile is available within our test application.

      All files with .cgi and .pl extension are handled by mod_perl. If exactly one file with .psgi extension exists in the top-level directory, the mod_perl will be autoconfigured to execute the PSGI application for any request URI path with Plack's mod_perl adaptor.

    • run

      This script is responsible for running the application, using the Apache web server.

    • usage*

      This script prints the usage of this image.

  • contrib/

    This folder contains a file with commonly used modules.

  • test/

    This folder contains the S2I test framework.

    • sample-test-app/

      A simple Perl application used for testing purposes by the S2I test framework.

    • run

      This script runs the S2I test framework.
