Useful Dockerfiles for the RHEL-ecosystem

Langdon White

I wonder if this is akin to writing where, I find, if you put the words down in a stream of consciousness manner, then " rewrite, rewrite, rewrite." As such, I am really excited about the efforts from the CentOS, Fedora...

Unexpected Feature of Software Collections

Langdon White

If you are anything like me, you live in perpetual fear of breaking your primary machine. The one you use for reading email, twitter, notifying you of meetings, etc. Over the years we have seen many attempts to alleviate this problem, things like etckeeper, using git to manage home ( duck it), regular backups (sure...), etc. Today, I stumbled across one of the benefits in Software Collections that I hadn't noticed before. My internal monologue went something like this: me...

Permanently Enable a Software Collection

Langdon White

Apologies that this has been so long in coming, but I was certain that we had already written a post on this subject. What subject you ask?

First, you just "source" the enable script from your .bashrc. For example source /opt/rh/python33/enable However, as this Red Hat kbase...

An Introduction to COPRs

Langdon White

It is also handy to be able to share the rpms with your friends :). In the past that has meant building all of the rpms for the various RHEL-ecosystem OSs and then finding somewhere you can host them and maintaining it yourself. What I am excited to tell...
