Harnessing Kubernetes – Cloud Foundry Container Runtime

November 13, 2017

A few weeks ago I attended Cloud Foundry summit Europe 2017 held in Basel, Switzerland.  One of the more interesting topics that came up was the “Cloud Foundry Container Runtime,” an effort formerly known as “Kubo.”

Kubo, which comes from “Kubernetes on Bosh,” was created jointly by Pivotal and Google in order to provide a simple way to deploy and operate production-ready Kubernetes clusters on premise and in the cloud.  Back in June, the Kubo code was donated to the Linux Foundation as an open source project.

To learn more about Cloud Foundry Container Runtime (nee Kubo) and the larger context it fits within I sat down with Ian Andrews, Vice President of Products at Pivotal.  Armed with only a pen and paper Ian provides an overview of the container runtime and explains how it differs from the Cloud Foundry application runtime, as well as which workloads are most appropriate for each.

Ian ends by walking us through the recently announced, Pivotal Container Service (PKS) that VMware and Pivotal worked on together with help from the Google cloud team (PKS is based on the Cloud Foundry container runtime with extra goodies thrown in).

Time markers

  • 00:00 –07:25      Intro/background: How Kubo came about and how it and Cloud Foundry (CF) elastic runtime were renamed “Cloud Foundry container runtime” and “Cloud Foundry application run time”
  • 07:25 – 24:00      Sketches out the CF architecture.  From there he goes through each of the two components that sit on top of BOSH:   CF container runtime and CF application run time.  He then compares the two runtimes
  • 24:00 – 28:55      Goes through Pivotal’s implementation of the above: Pivotal Cloud Foundry and Pivotal Container Service.

Learning about CoreOS and Tectonic

January 6, 2016

With today’s post we are five interviews into the videos I took at Kubecon with three remaining.

Today’s interviewee is Rob Szumski, one of the early employees of CoreOS.  Rob explains CoreOS, Tectonic and where CoreOS is going from here.

Some of the ground Rob covers

  • CoreOS began as an operating system for large scale clusters and how Docker came around at just the right time and worked with CoreOS
  • CoreOS as the original micro OS
  • The components of Tectonic – How you should deploy your containers, on top of: kubernetes, flannel, coreOS, etc; it also comes with support and architectural help
  • Whats on tap for CoreOS and Tectonic – tools and more

Red Hat launches OpenShift v3.1, full of Docker/Kubernetes goodness

January 4, 2016

Im just getting around to publishing my interviews from KubeCon back in November

Today’s interview features Red Hat’s Grant Shipley, director of developer advocacy for “container application platform” OpenShift.  Grant talks about the launching of OpenShift v3.1 and what’s ahead.

Some of the ground Grant covers:

  • Announcing 3.1, the latest upstream version of Red Hat’s open source project OpenShift Origin
  • Enterprise comes with support for docker/kubernetes in production
  • Moving away from “PaaS” to “container application platform”
  • All functionality exposed via apis; cli and web console tools for ops; ops has full control but devs can self service
  • How it works with Ansible (or Puppet and Chef)
  • Whats next going forward: continuing to focus on dev experience whether they’re using node.js or Java

Google Kubernete’s new community lead: Sarah Novotny

November 30, 2015

A couple of weeks ago I attended KubeCon in San Francisco.  There were a series of talks as well as a bunch of vendors who were there in mini-booths chatting with folks and showing off what they do.  As always, the part I get the most out of at conferences like this is the “hallway track” where I get to chat one-on-one with various folks.

One such folk was Sarah Novotny, who recently joined Google as the first Kubernetes community lead.  Check out the video below where Sarah talks about her goals for the community, how it will fit with the Cloud Native Computing Foundation and how she hopes to extend this beyond a Google only effort.

Learning about VMware’s Photon Controller

November 18, 2015

Last week I headed out to San Francisco to attend Kubecon and soak in the Kubernetes and devops-ecosystem goodness.  As the event landing page explained:

KubeCon 2015 is the first inaugural community Kubernetes conference, fully dedicated to education and community engagement focused on early Kubernetes, production users and contributors.

As I normally do at events like this I prowled the halls to look for folks doing cool stuff to interview with my trusty Flipcam.

One of the people I chatted with was Kenneth Jung, developer lead on the Photon Controller team at VMware.  The Photon Controller, in short, is a cloud scale IO solution for managing ESX.  (One of the things Kenneth alludes to is the open sourcing of the Controller which ended up happening yesterday.)

Some of the ground Kenneth covers

  • What is the photon controller – cloud scale io solution for managing ESX
  • How the cluster manager makes deployment and management of large of container frameworks like Kubernetes, easy
  • How VMware looks at VMs vs containers
  • The Photon microvisor + Photon OS used in Photon Controller
  • They will have a cloud foundry release early next year

ContainerCon: How Google helps developers with Kubernetes

August 26, 2015

Last week at Container/LinuxCon I conducted  a handful of video interviews.  Video number three stars Brian Dorsey from Google. Brian works with developers to get them up to speed with Kubernetes.

Here’s what Brian had to say:

Some of the ground Brian covers

  • Brian’s focus on cloud-building developers, specifically those working on Kubernetes
  • Key partners such as Red Hat, CoreOS, Kismatic and many, many more
  • How Brian and the team reach developers  (events, blogs, videos, sample code…)
  • Where he sees Kubernetes going over the next year

Introducing Kubernetes 1.0 and the Cloud Native Computing foundation

July 22, 2015

This morning at OSCON a special event was held to announce the launch of Kubernetes 1.0 (Google’s open source container management framework) as well as the introduction of the Cloud Native Computing foundation.

One of the key speakers at the event was Craig McLuckie of Google who is a founding member of Kubernetes’ team.  Craig has also been working with the Linux Foundation to set up the Cloud Native Computing foundation.

I sat down with Craig for a quick chat regarding both of these efforts.

Some of the ground Craig covers:

  • Craig’s role at Google and his relationship with Kubernetes
  • Today’s announcement as it relates to both Kubernetes 1.0 and the Cloud Native Computing foundation.
  • Where does Craig see Kubernetes going over the next year and what new workloads will it run

Container management and landscape

July 17, 2015

Back at the end of April I gave an internal presentation laying out a high level overview of the container and container management space.   I pulled this together using public info.

Needless to say big things have happened since I created it,  most notably the announcement of the Open Container Project.  That being said it I feel it still offers a good general feel for the players and how they fit together.

Azure architect talks about Kubernetes and the future of PaaS

September 24, 2014

Here is the third of four interviews that I conducted last week at the Cloud Standards Customer Council.  The theme of the conference was “preparing for the post-IaaS phase of cloud adoption” and there was quite a bit of talk around the role that PaaS would play in that future.

The last session of the morning, before we broke for lunch, was a panel centered around Current and Future PaaS Trends.   After the panel ended I sat down with panelist John Gossman, architect on Microsoft Azure.  John, an app developer by origin, focuses on the developer’s experience on the cloud.

Below John talks working with Google on Kubernetes and getting it to work on Azure as well as the potential future of PaaS as a runtime that sits on top of IaaS.

Stay tuned for my next post when I will conclude my mini series from the Cloud Standards Customer Council meeting with an interview with Bernard Golden.
