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…


StackStorm for Kubernetes just took a giant leap forward (beta)

  came up with it one morning around 4am while trying to get the baby to sleep. i’m pretty proud. mostly because it works 😉  – Andy Moore   As many of you know, my team began integrating StackStorm with Kubernetes via ThirdPartyResources(TPR) which we showed off at KubeCon_London in March 2016. This was a great…


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…


Kubernetes continuous deployment pipeline

Just figured I would add this for posterity sake. The Pearson Bitesize team open sourced our deployment pipeline plugin at KubeCon Seattle on Monday Nov. 8th 2016. Kubernetes Continuous Deployment Pipeline https://github.com/pearsontechnology/deployment-pipeline-jenkins-plugin  


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 container guarantees (and oversubscription)

Reading through the release notes of Kubernetes 1.4, I came across some fantastical news. News so good, I should have expected it. News that could not come at a better time. I’m talking about container guarantees, or what Kubernetes calls Resource Quality of Service. Let me be frank here, its like the Kubernetes team was…


Cluster Consul using Kubernetes API

Recently we had the desire to cluster Consul (Hashicorps K/V store) without calling out to Atlas. We deploy many clusters per day as we are constantly testing and we want Consul to simply bring itself up without having to reach out over the internet. So we added a few changes to our Consul setup, so here…


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…
