Red Hat OpenShift Container Platform

Ready to develop container application in just over 4 minutes? Since I started playing around with OpenShift in its various forms, such as Online with cartridges and then later as containerized images, nothing has gotten me more excited than the availability of the Red Hat Container Development Kit (CDK). This kit has made it possible to easily gain access to a full, product based installation of OpenShift as you would interact with it in application development in just minutes. While...

With the release of the Red Hat Container Development Kit (CDK), it’s been easier to set up a development environment with OpenShift to create, develop and test your own containerized applications, and easier evaluate different CI/CD strategies with Jenkins --- strategies that reflect your team's unique culture. However, when you want to access applications by their DNS names, you cannot do so because there is no DNS server pointing to that name. That is, of course, until now! Vagrant provides...

Recent: Red Hat was invited to be part of Eclipse Che keynote at EclipseCon 2016 and Pete Muir gave a quick look at working with OpenShift and Eclipse Che. When we create software today , we often hit a brick wall and waste many hours because creating copies of another system is far too hard. We create copies for many reasons - a few common examples are: replicating production issues; asking another developer for help; running test suites; copying the...

Cloud based technology offers the ability to build, deploy and scale applications with ease; however, deploying to the cloud is only half of the battle. How cloud applications are monitored becomes a paramount concern with operations teams. When issues arise, teams and their monitoring systems must be able to detect, react, and rectify the situation. CPU, system memory, and disk space are three common indicators used to monitor applications, and are typically reported by the operating system. However, for Java...

Introduction A way organizations deal with the progression towards a more connected and API driven world, is by implementing a lightweight SOA/REST API architecture for application services to simplify the delivery of modern apps and services. In the following blog series, we're going to show how solutions based on 3scale and Red Hat JBoss Fuse enable organizations to create right interfaces to their internal systems thus enabling them to thrive in the networked, integrated economy. Among the API Management scenarios...

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...

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...

Letting the containers out of containment I have written a lot about *Containing the Containers*, e.g. * Are Docker containers really secure?* and * Bringing new security features to Docker*. However, what if you want to ship a container that needs to have access to the host system or other containers? Well, let's talk about removing all the security! Safely? Packaging Model I envision a world where lots of software gets shipped in image format. In other words, the application...
