#DOXLON March 2017

12/04/2017   Industry insights   LinuxRecruit community  

Our March meetup was our 30th DOXLON event, and featured an epic lineup of speakers, including a live stream from KubeCon founder and EIR at Quantum Joseph Jacks, and a presentation from Bobby DeVeaux of UKCloud, who presented his most recent project, a production-ready scalable Docker Swarm using Terraform and Packer. We also had Mangirdas Judeikis dive into OpenShift and how it works with containers, and Cameron Adams, who took us through how ITV have been using Docker & Selenium to reduce their build pipeline from 4 hours to 40 minutes.

Below you can find videos of each talk, which we hope you find useful. We’re always interested in speaking to people who would like to present at future events -  so you if you have something interesting you’d like to talk about, please do get in touch.


Cameron Adams - 6 x Faster CI 

Part of the Common Platform Engineering team at ITV, Cameron tells the story of how ITV have used Docker and Selenium to take their build pipeline from 4 hours to 40 minutes. 

Bobby DeVeaux - Building a production-ready fully-scalable Docker Swarm using Terraform & Packer on OpenStack

Bobby is a Consultant DevOps Engineer who currently works with UK Cloud’s clients to help them understand DevOps, how to improve their automation and migrate to a cloud-native environment. Bobby has over 20 years experience working with the web and has most recently been working with public sector clients on their latest projects.

Joseph Jacks - Native, Distributed Storage for Kubernetes

Modern software storage systems are inherently complex. They are composed of numerous distributed components, require careful balancing of resources, and have stringent performance requirements. If you're running your applications in a public cloud you're typically shielded from this complexity and can utilize managed storage services like EBS, S3 and EFS. If you're running on-premise, however, your choices are quite limited and typically result in using traditional big-iron storage systems. In this talk, Joseph Jacks, who is a founder of Kismatic (the enterprise Kubernetes company, now Apprenda) and a founder of KubeCon, will walk through deploying and running a production-ready storage cluster using Kubernetes. Storage nodes can run as pods and enumerate the available storage devices within the cluster. JJ will show how some of the features of Kubernetes including controllers/operators, third-party resources, resource management, and rolling upgrades can lead to more powerful and resilient storage clusters.


Mangirdas Judeikis - OpenShift for the Corporate Containers Developer

Mangirdas from Red Hat delivers a technical talk for developers interested in getting a first-hand drive through of OpenShift. During this session Mangirdas covers:

  • OpenShift vs Kubernetes - what OpenShift does and what k8s doesn’t, and some myths broken
  • Docker implementation and why it’s challenging to run native Docker in corporate environments
  • Developer experience in highly controlled environments
  • Corporate security and compliance

A Short Demo representing some common use cases:

  • Dockerfile Build - How to build a dockerfile using docker and OpenShift.
  • How to run it, debug it, and get almost everything you get from docker but in a controlled corporate environment.
  • "I have code - run it, please". How to do it, and why it's good for your Enterprise.


DOXLON is a monthly meetup in London organised by us at LinuxRecruit, and Outlyer, to exchange some of the latest ideas and technologies for running online services through two or three short presentations by invited speakers, and a chance to chat it after over drinks and pizza with like-minded people.

We started this event as we believe DevOps practices and ideas are the future of technology, and we have seen an insatiable demand for more knowledge about it from teams running online/cloud services in London. We now run it monthly and have become London's largest DevOps Meetup attracting a diverse and curious crowd.
