Kubernetes

So you finally surrendered to containers and discovered that they solve a lot of problems and have a lot of advantages: First: Containers are immutable - The OS, library versions, configurations, folders, and application are all wrapped inside the container. You guarantee that the same image that was tested in QA will reach the production environment with the same behaviour. Second: Containers are lightweight - The memory footprint of a container is small. Instead of hundreds or thousands of MBs...

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...

Note: The Twelve-Factor app is a methodology for building apps in modern cloud environments. Read more at http://12factor.net/. Factor Relationship Codebase One codebase tracked in revision control, many deploys...

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...

We just started this year and a lot has happened already. From now on, I will summarize the monthly happenings in JBoss to catch in one place. A Year in Review First thing a new year is all about is looking back. There's been plenty of recaps about 2014 for example by Eric Schabell who highlighted the most important events for JBoss Integration & BPM. Did you know, that there is a book called " OpenShift Primer" which got completely...

If one thing survived all the New Year parties, it is Docker. It was hot at the end of 2014 and it looks like it is getting even hotter in 2015. And Red Hat is one of the key drivers behind the adoption of this amazing container technology. This is a short summary blog post about a bunch of resources to get you started with Java EE, WildFly and Microservices on Docker mostly collecting resources and information from the JBoss...

Crunchy has been working with the OpenShift team for some time and witnessed the value proposition of combining PostgreSQL, a leading open source object...

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...
