Cornavirus has arrived at the global level, it is likely only a matter of time before it is declared a world pandemic. Most are wondering how long it will stay and when will things go back to normal? Personally I think we reached the point, there will be no going back and that is not necessarily a bad thing. In this article we will discuss why the cornavirus is just as much an opportunity for the human race as it is a threat. We will discuss how technology can help and how a global world can function, disconnected.
In this article we will focus on installing and configuring OpenStack Train using RDO and the packstack installer. RDO is a community platform around Red Hat’s Enterprise OpenStack Distribution. 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.
In this article we will introduce the concept of operators and provide a hands-on guide to building your very first operator. I will show you how to create a development environment with everything needed. Using the Operator SDK we will learn how to create boilerplate code, build and deploy an operator. A followup article is also planned that will go deeper into operator development so stay tuned!
In this article we will look at providing an automation platform for edge computing. Generally I would say edge computing is about moving data-handling away from centralized systems, towards local sources of data capture. An edge can be a remote office, server, laptop, tablet, smartphone or IoT anything endpoint. Edge computing is really just taking distributed computing one step further and removing the requirement to have always-connected network segments.
Andi and I in the lounge on our way back from a sales kickoff in 2016
It has been a few weeks since I learned of the tragic passing of my friend, colleague and mentor Andreas Neeb. I am just now able to gather my thoughts, in an attempt to pass on the lessons I learned from one of the truly great, Red Hatters. First I would like to remember how Andi and I became colleagues and friends.
Volume snapshots are the ability to create snapshots of persistent volumes in kubernetes using the container storage interface (csi) driver. The csi driver allows storage solutions to integrate into kubernetes and expose their technologies. Snapshots of course, have been and are a key technology when discussing data workloads because they enable backup/restore seamlessly, on-demand and in a split second. Even though volume snapshots are in the alpha stage, several storage providers already have integrations, including one that is very interesting, Ceph RDB.
In this article we start a new journey, automated infrastructure in the on-premise datacenter. We will deploy OpenShift 4.2 on OpenStack. As I am sure you are aware, OpenShift is Red Hat’s enterprise kubernetes platform. Kubernetes is of course the brains but by itself is not a platform. OpenShift brings with kubernetes, monitoring, aggregate logging, container registry, security, automated deployment/upgrade, developer experience, huge middleware tooling built around JBoss, serverless frameworks, ISTIO (service mesh), CI/CD integration and the key word “ENTERPRISE“.
