Welcome to the RackN and Digital Rebar Weekly Review. You will find the latest news related to Edge, DevOps, SRE and other relevant topics.

Immutable Infrastructure

Immutable infrastructure offers IT a new deployment methodology of create / destroy / repeat from a fixed image for deploying services vs the more common method of deploying once and then patching regularly to keep a service in operations. Continually tearing down and launching fixed images solves challenges such as hacking, version control, and unknown service status.

RackN automation and provisioning management simplify the immutable infrastructure methodology allowing IT team to focus on issues other than version control and hacked services.

Building Kubernetes based highly customizable environments on OpenStack with Kubespray

This talk was given on November 8 at the OpenStack Summit Sydney event.

Abstract

Kubespray (formerly Kargo) – is a project under Kubernetes community umbrella. From the technical side, it is a set of tools, that bring the possibility to deploy production-ready Kubernetes cluster easily.

Kubespray supports multiple Linux distributions to host the Kubernetes clusters (including Ubuntu, Debian, CentOS/RHEL and Container Linux by CoreOS), multiple cloud providers to be used as an underlay for the cluster deployment (AWS, DigitalOcean, GCE, Azure and OpenStack), together with the ability to use Bare Metal installations. It may consume Docker and rkt as the container runtimes for the containerized workloads, as well as a wide variety of networking plugins (Flannel, Weave, Calico and Canal); or built-in cloud provider networking instead.

In this talk we will describe the options of using Kubespray for building Kubernetes environments on OpenStack and how can you benefit from it.

What can I expect to learn?

Active Kubernetes community members, Ihor Dvoretskyi and Rob Hirschfeld, will highlight the benefits of running Kubernetes on top of OpenStack, and will describe how Kubespray may simplify the cluster building and management options for these use-cases.
