A Practical Introduction to the Docker Registry Server
Background One of the key advantages of using Docker is it’s centralized image management server, called a Registry Server. The Docker project, as well as Red Hat, maintain public registry servers which host supported images. The Docker project also provides an Open Source version of the Registry server which can be deployed on premise in

Deep Dive: Rebasing vs. Backporting
Background Impetus Recently, I saw a discussion was started, asking about the importance of the operating system on the LinkedIn OpenStack group: Ubuntu can overtake Red Hat in private clouds because the OS doesn’t really matter I found the conversation wildly interesting because several people expressed reasons for why they think the operating system does
A Practical Introduction to Docker Containers
Background Why Docker has quite an amount of buzz around it today because it makes so many things easy that were difficult with virtual machines. Docker containers makes it easy for Developers, Systems Administrators, Architects, Consultants and others to quickly test a piece of software in a container; much quicker than a virtual machine, and

CentOS Post Mortem & Analysis
Background I manage the crunchtools lab and the infrastructure for this blog similar to a development data center. I have a rigorous weekly checklist, which includes optionally applying operating system patches as they are available. I do not perform the updates every week because of time constraints, but when I do, I patch all of
Red Hat Enterprise Virtualization (RHEV) & Identity, Policy, Audit (IPA)
Background In my ever evolving lab, it came time to integrate Red Hat Enterprise Linux (RHEV) with Identity, Policy, Audit (IPA).There were a few caveats and searching Google didn’t help, so hopefully this article can save you some time. Integrating the two was fairly straitforward. The biggest challenge was finding a quick and easy way

Devops with Bash
This presentation walks through some of the software development processes used to develop Shiva, a mass ssh client. The development of Shiva was used as a teaching aid for a class taught at Ohio Linux Fest 2012. Shiva was used to demonstrate concepts such as good command line interface design, testing, configuration design and advanced features of Bash, such as background functions. This presentation and associated class were developed to help systems adminsitrators think more like developers.
RHEL6 and Cisco WRVS4400N Networking
Background This weekend I decided to upgrade my home network with a Cisco WRVS4400N wireless router. Like a typical router it can provide standard wireless services WPA2, DHCP, etc, but the this model also provides support for four distinct VLANs and four distinct SSIDs. This has allowed me to create separate networks for work, play,
