Case study repost: Red Hat Software Collections – ScriptScribe


Dave and I first chatted last year about Software Collections when they first became available, and less than a year later he’s written up this great summary of his experience with them.


“Red Hat Software Collections

By Scott Merrill

In the beginning

“When I started working at CoverMyMeds, I inherited a server infrastructure that made sense for where the company was at the time. There was one full-time system administrator and a small group of developers. There were only a handful of production servers running a small collection of applications. The majority of applications were Ruby, and Ruby was installed onto the servers using RVM, the Ruby Version Manager.

“We had a number of PHP applications running on different versions of that language, including a custom RPM for a specific version of PHP for one app. The Red Hat default version of PHP was 5.3, which was already ancient by PHP standards.” Continue reading

Using Mock to build Python27 Software Collections packages for RHEL6


Have you wanted to use software collections but found packaging has kept you at bay? Tried rebuilding a package only to find it give you weird errors you’ve not seen before? In this blog post we’ll learn how to configure and use mock to build RPM packages for the Python 2.7 Software Collection. Along the way we’ll learn why we can’t use standard mock configurations, and what makes Software Collections (SCL) mock configurations different.

How to add packages to Python 2.7 Software Collection


As Software Collections are getting popular, there are more and more people asking how they can build their own collections and/or extend collections in RHSCL. In this article, I will demonstrate how to extend python27 collection from RHSCL 1.2, adding a simple Python extension library. (Note that the same steps can be applied to the python33 collection.) I’m going to work on a RHEL 6 machine throughout this whole tutorial. I’m assuming that readers have basic knowledge of RPM building and Software Collections concept.

Dockerfiles now available for Red Hat Software Collections


Shipping_containers_at_ClydeWe recently announced that we’ve made available a set of Dockerfiles for Red Hat Software Collections.  We are making these available since we think they may be useful to customers looking to build more complex application containers on top of RHEL and RHSCL. We don’t intend the Dockerfiles to produce useful standalone images which you’ll immediately put in production – the Docker images which these create are very simple containers which give you RHEL plus the basic set of packages from a particular RHSCL collection.

There are two different ways to get your hands on the Dockerfiles:

  1. From the upstream source at github 
  2. From a new package, rhscl-dockerfiles, which we’ve shipped in the RHSCL channels – both for RHEL6 and RHEL7
