It allows you to test the latest OpenStack capabilities on a stable platform such as Red Hat Enterprise Linux (RHEL) or CentOS. This guide will take you through setting up Hetzner root server, preparing environment for OpenStack, installing the OpenStack Train release, adding a floating ip subnet through OVS, configuring networking, security groups, flavors, images and are other OpenStack related services. The outcome is a working OpenStack environment based on the Train release that you can use as a baseline for testing your applications using OpenStack capabilities. The installation will create an all-in-one deployment however you can use this guide to create a multi-node deployment as well.

Overview

Immediately after Solomon Hykes first showed Docker to the public at PyCon in 2013, in his now famous “docker run demo”, IT folk started asking, what does this mean for virtualization? We only spent the previous 10-15 years virtualizing, seemingly everything, so understandably people were slightly apprehensive. Industries had been built and careers established, clearly virtualization would be an important part of the future and not simply replaced, right?

In this article we will aim to understand the value of virtualization in a container-driven world, explore the current virtualization capabilities in Kubernetes and get started with Container Native Virtualization (Kubevirt) using Red Hat’s Kubernetes enterprise distribution, OpenShift.

Overview

Often a lot of people seem to confuse Kubernetes with OpenShift or a platform-as-a-service (PaaS). Kubernetes is of course on it’s own, not. It is an orchestration layer or technology for containers but a lot is missing to really call it a platform. OpenShift is Red Hat enterprise Kubernetes platform. It contains Kubernetes but also a whole lot more which make it a true platform. So which is right for you? It depends a lot on your requirements and what you are trying to achieve. The purpose of this article is to setup an environment for running a workshop that compares the Kubernetes experience with OpenShift in order to gain more insight and understanding in what you may actually need. Many people sit down with slides or at a whiteboard, but I really find that is not adequate and you really need to experience it, first hand.
