Open Source – Environment Operator

The day has finally come. Today we are announcing our open source project Environment Operator (EO). Environment Operator is used throughout our project and has rapidly gained a name for itself as being well written and well thought out. Props go out to Simas Cepaitis, Cristian Radu and Ben Somogyi who have all contributed. At its core,…


Kubernetes – PodPresets

Podpresets in Kubernetes are a cool new addition to container orchestration in v1.7 as an alpha capability. At first they seem relatively simple but when I began to realize their current AND potential value, I came up with all kinds of potential use cases. Basically Podpresets inject configuration into pods for any pod using a…


Kong API Gateway

  Why an API gateway for micro services? API Gateways can be an important part of the Micro Services / Serverless Architecture. API gateways can assist with: managing multiple protocols working with an aggregator for web components across multiple backend micro services (backend for front-end) reducing the number of round trip requests managing auth between…


Open Source – Bitesize-controllers

The Bitesize team has been working with the nginx-controller for quite some time. Over that time we have modified, updated, coerced it to our will and its high time we open source this thing. First I want to call out the engineers that have contributed to this controller and make sure they get the recognition…


deployment pipeline options for Kubernetes

In the last several months various deployment (CI/CD) pipelines have cropped up within the Kubernetes community and our team also released one at KubeCon Seattle 2016. As a result I’ve been asked on a couple different occasions why we built our own. So here is my take. We began this endeavor sometime late 2015. You…


KubeCon Seattle Video

Finally posting this after my speaking engagement at KubeCon_Seattle in November 2016. Thanks to all that came. My hope is releasing our Deployment Pipeline will help the Kubernetes community build an ecosystem of open source CI/CD pipelines to support an awesome platform. Below the video are links to the various open source projects we have…


Kube-DNS – a little tuning

We recently upgraded Kube-dns.

Having used SkyDNS up to this point, we ran into some unexpected performance issues. In particular we were seeing pretty exaggerated response times from kube-dns when making requests it is not authoritative on (i.e. not cluster.local). Fortunately this was on a cluster not yet serving any production customers. It took several hours…


Kubernetes Init Containers

Kubernetes Init containers. Alright, I’m just going to tell the truth here. When I first started reading about them, I didn’t get it. I thought to myself, “with all the other stuff they could be doing right now at this early stage of Kubernetes, what the hell were they thinking? Seriously?” But that’s because I…


Kubernetes-authz-webhook

I’m just gonna leave this here. From our team to yours. https://github.com/pearsontechnology/bitesize-authz-webhook       All props go to Simas  


Kubernetes/PaaS: Automated Test Framework

First off, mad props go out to Ben Somogyi and Martin Devlin. They have been digging deep on this and have made great progress. I wanted to make sure I call them out and all the honors go to them. I just have the honor of telling you about it. You might be thinking right…
