Community Blogpost Round-up: April 20

The last month has been busy to say the least, which is why we haven’t gotten around to posting a recent Blogpost Roundup, but it looks like you all have been busy as well! Thanks as always for continuing to share your knowledge around RDO and OpenStack. Enjoy!

Lessons from OpenStack Telemetry: Deflation by Julien Danjou

This post is the second and final episode of Lessons from OpenStack Telemetry. If you have missed the first post, you can read it here.


Unit tests on RDO package builds by jpena

Unit tests are used to verify that individual units of source code work according to a defined spec. While this may sound complicated to understand, in short it means that we try to verify that each part of our source code works as expected, without having to run the full program they belong to.


Red Hatters To Present at More Than 50 OpenStack Summit Vancouver Sessions by Peter Pawelski, Product Marketing Manager, Red Hat OpenStack Platform

OpenStack Summit returns to Vancouver, Canada May 21-24, 2018, and Red Hat will be returning as well with as big of a presence as ever. Red Hat will be a headline sponsor of the event, and you’ll have plenty of ways to interact with us during the show.


Lessons from OpenStack Telemetry: Incubation by Julien Danjou

It was mostly around that time in 2012 that I and a couple of fellow open-source enthusiasts started working on Ceilometer, the first piece of software from the OpenStack Telemetry project. Six years have passed since then. I’ve been thinking about this blog post for several months (even years, maybe), but lacked the time and the hindsight needed to lay out my thoughts properly. In a series of posts, I would like to share my observations about the Ceilometer development history.


Comparing Keystone and Istio RBAC by Adam Young

To continue with my previous investigation to Istio, and to continue the comparison with the comparable parts of OpenStack, I want to dig deeper into how Istio performs RBAC. Specifically, I would love to answer the question: could Istio be used to perform the Role check?


Scaling ARA to a million Ansible playbooks a month by David Moreau Simard

The OpenStack community runs over 300 000 CI jobs with Ansible every month with the help of the awesome Zuul.


Comparing Istio and Keystone Middleware by Adam Young

One way to learn a new technology is to compare it to what you already know. I’ve heard a lot about Istio, and I don’t really grok it yet, so this post is my attempt to get the ideas solid in my own head, and to spur conversations out there.


Heading to Red Hat Summit? Here’s how you can learn more about OpenStack. by Peter Pawelski, Product Marketing Manager, Red Hat OpenStack Platform

If you’re lucky enough to be headed to the event in San Francisco, May 8-10, we’re looking forward to seeing you. If you can’t go, fear not, there will be ways to see some of what’s going on there remotely. And if you’re undecided, what are you waiting for? Register today. 


Multiple 1-Wire Buses on the Raspberry Pi by Lars Kellogg-Stedman

The DS18B20 is a popular temperature sensor that uses the 1-Wire protocol for communication. Recent versions of the Linux kernel include a kernel driver for this protocol, making it relatively convenient to connect one or more of these devices to a Raspberry Pi or similar device.


An Introduction to Fast Forward Upgrades in Red Hat OpenStack Platform by Maria Bracho, Principal Product Manager OpenStack

OpenStack momentum continues to grow as an important component of hybrid cloud, particularly among enterprise and telco. At Red Hat, we continue to seek ways to make it easier to consume. We offer extensive, industry-leading training, an easy to use installation and lifecycle management tool, and the advantage of being able to support the deployment from the app layer to the OS layer.


Ceph integration topics at OpenStack PTG by Giulio Fidente

I wanted to share a short summary of the discussions happened around the Ceph integration (in TripleO) at the OpenStack PTG.


Generating a list of URL patterns for OpenStack services. by Adam Young

Last year at the Boston OpenStack summit, I presented on an Idea of using URL patterns to enforce RBAC. While this idea is on hold for the time being, a related approach is moving forward building on top of application credentials. In this approach, the set of acceptable URLs is added to the role, so it is an additional check. This is a lower barrier to entry approach.
