When you are setting up a self-contained OpenShift v3 cluster, you usually run into the problem of how to resolve host names, local cluster addresses, application routes, and external names correctly everywhere. For a production deployment, a networking engineer would typically be responsible for working this out, but if you are just trying it out, getting properly hooked into organizational DNS can be daunting if not forbidden by policy. Fortunately, if needed, you can handle DNS entirely yourself. Assumptions Let's...

What are user namespaces? Sticking with the apartment complex analogy, the numbering of users and groups have historically been the same in every container and in the underlying host, just like public channel 10 is generally the same in every unit in an apartment building. But, imagine that people in different apartments are getting their television signal from different cable and satellite companies. Channel 10 is now different for each person. It might be sports for one person, and news...

In the current world of DevOps, Continuous Delivery, Microservices, and PaaS many organizations want to know how Software Governance practices and requirements fit. Some of this comes from a regulatory perspective, ensuring compliance (e.g HIPAA/PHI, SOX, PCI) and auditing requirements are met. Another perspective focuses on existing technology standards, design practices, and application architecture. At the same time developers and teams are being told to be more agile, adaptable, and self-directed. How do we achieve the latter while mitigating the...

By Ben Parees There have been a lot of announcements lately around Red Hat’s OpenShift v3 plans, specifically around Docker and Kubernetes. OpenShift v3 is being built around the central idea of user applications running in Docker containers with scheduling/management support provided by the Kubernetes project, and augmented deployment, orchestration, and routing functionality built on top. This means if you can run your application in a container, you can run it in OpenShift v3. Let’s dig in and see just...

If you ask three people what they think DevOps is, you’ll get three answers: “a way of running an IT department”, “a culture”, “something to do with Phoenix”. Ask a fourth person and you might hear “You can use OpenShift for that”. To see what DevOps has to do with the world’s favourite PaaS, I went along to the “OpenShift By Red Hat: The PaaS for DevOps” technical deep dive in Brisbane that was given as part of a road...

About a year ago, Red Hat Product Security decided to move its blog, the Red Hat Security Blog, off of WordPress.com's infrastructure and onto Red Hat's OpenShift. There were some initial growing pains since this was a relatively new thing to do, but it wasn't long before the blog was in a stable environment. There were plans to put the application on a larger gear (it was hosted on a small gear) and to make it scalable (it wasn't), but...
