OpenShift Origin

The key to a good development environment almost always comes down to how long it takes for changes you make to take effect. With any compiled language, there is often a lot of setup work involved to optimize deployment speed. Thankfully, one of the ... [More] promises of containers is it allows for patterns to be standardized and repackaged as reusable images that do a lot of the heavy lifting for you. [Less]

The OpenShift Commons Gathering will bring together the brightest technical minds to discuss the future of OpenShift and its related upstream open source projects. With OpenShift Container Platform quickly gaining adoption around the world, the ... [More] OpenShift Commons Gathering will feature talks from upstream project leads and case studies from users like Red Hat, Google, Microsoft Azure, Amadeus, T-Systems, Volvo, Weave, CNCF and more. This event will also include face-to-face meetings for all the OpenShift Commons Special Interest Groups and allow ample time for peer-to-peer networking. [Less]

The OpenShift Developer Evangelist team is happy to release the first iteration of our work with Katacoda – interactive OpenShift tutorials! The idea with these tutorials is that you get your own individual OpenShift environment with instructions ... [More] right next to it. You can work through the instructions at your own pace but you are using a fully-functioning OpenShift environment with working URLs and all. [Less]

OpenShift provides a built-in monitoring tool called Hawkular. That tool is in charge of collecting metrics from Docker containers through the Kubernetes interface and storing, aggregating, and visualizing them. The metrics collected are CPU, Memory ... [More] , Disk, and Network usage. Hawkular offers a “black-box” view of container performance but does not deal with application metrics like service performance or distribution of response time through application layers. For this specific case, the Hawkular community is working on another module called Hawkular APM that provides insight into the way an application executes across multiple (micro) services in a distributed (e.g. cloud) environment.

After almost 100,000 downloads, the time has come to retire the OpenShift All-In-One VM. The intent of the VM was to give developers a simple and easy way to bring up OpenShift on their local machine for development purposes. In the meantime, there ... [More] was movement within the Kubernetes community to create MiniKube – a means to run a Kubernetes “cluster” on your local machine. Jimmi Dyson saw this work and started MiniShift which built off MiniKube except for OpenShift. It fulfills all the original use cases we had for the All-In-One with the added bonus of actually having an engineering team maintaining it! [Less]

OpenShift can integrate with underlying infrastructure, enabling OpenShift to dynamically interact with infrastructure and extend its functionality. Specifically, this can allow us to set up OpenShift to process a PersistentVolumeClaim and then ... [More] allocate that storage dynamically. I am going to cover what is needed to get started with dynamically provisioning storage, including cloud provider configuration, StorageClasses, and the Default StorageClass. [Less]

In this briefing, Alban Crequy of Kinvolk.io gives a quick introduction to the Weave Scope open source tool for monitoring for containers running on Kubernetes, then dives into using the Traffic Control plugin to test applications and detect degraded networks.

After you play around with OpenShift locally, you will come to the realization that you would enjoy having a 24/7 install of OpenShift that you can publicly host your projects on. This is where a lot of Developers stumble because they aren’t system ... [More] administrators. For that reason, I took some time to create a video that shows how to install OpenShift Origin 1.4 from start to finish. This means that I create a bare virtual machine, install the operating system, install dependencies (like docker), and then use ansible to install OpenShift. After the install, I then show how to setup wildcard DNS for a public hostname. All in under 30 minutes. [Less]

In this briefing, Dimitri Stiliadis, CEO, Co-Founder of Aporeto gives an introduction to the Trireme open source project. Trireme takes a different approach to application segmentation by treating the problem as what it is: an authentication and ... [More] authorization problem. Every application component, such as process, a container, a Kubernetes POD, has an identity. A segmentation function is a simple policy that defines identities of the endpoints that are allowed to communicate with each other. [Less]
