I recently had the privilege to help organize DevOpsDays Texas 2021, a virtual event that we ran to try and scratch our DevOpsDays itch given that in-person conferences won’t be happening any time soon.

Sorry for the long preamble, feel free to just skip straight to the technical details.

Note: I have an updated, simpler version of this on Github with saved exports of profile and sources here.

Zoom meetings are great for a small number of people, and if you’re willing to buy a Webinar license you can also use it for a full on webinar (although there are some interesting restrictions to webinars, like you can’t have breakout rooms).

Welcome to 2020.

After what seems like an eternity I finally got added to the GitHub Actions beta a few days ago.

Introduction Welcome to a three part blog series on Creating a Helm Chart Repository.

Introduction Welcome to a three part blog series on Creating a Helm Chart Repository.

Note: If this topic has peaked your interest, you can join me for a Webinar on August 15 where I’ll dive deep into Cloud Native Operations with Kubernetes and CI/CD Pipelines.

In previous installments of Spring into Kubernetes I’ve shown you how to build images, deploy applications and write a Helm Chart for Spring applications.

Introduction In this installment of Spring into Kubernetes we’ll be looking at using Helm to install our Spring application to Kubernetes.

While investigating running Spring applications on Kubernetes I discovered that a lot of the existing example Spring applications do not have a Dockerfile in their git repository.

Habitat is a project from Chef that provides you a reasonably simple way to build, package, and configure your application.

I recently found myself writing instructions on how to deploy an application to several Kubernetes platform and ended up writing a different Kubernetes manifests for each platform. 95% of the content was the same with just a few different directives based…

Previously I showed how to run a basic secure Docker Registry.

There comes a time in everybody’s life where they realize they have to run their own Docker Registry.

By default Docker (and by extension Docker Swarm) has no authentication or authorization on its API, relying instead on the filesystem security of its unix socket /var/run/docker.sock which by default is only accessible by the root user.

Given Docker’s propensity for creating easy to use tools it shouldn’t come as a surprise that Docker Swarm is one of the easier to understand and run of the “Docker Clustering” options currently out there.

I have recently had a number of lengthy discussions on the Twitter about Interop, Users, and Ecosystems.

Docker images are “supposed” to be small and fast.

Unless you’ve been living under a rock (in which case I envy you) you’ve heard a fair bit about The Twelve-Factor App.

For some values of ‘right’ Almost since Docker was first introduced to the world there has been a fairly strong push to keeping containers to be single process.

“See how this sparkly devop princess bakes bread every day with almost no effort at all with this one weird trick” Store bought bread is shit.

EZ Bake came from an idea I had while watching the HangOps episode 2014-04-11 in which they were talking about Docker and Config Management being complementary rather than adversary.

I recently did a presentation at the Cloud Austin meetup titled Docking with Unicorns about new PAAS on the block DEIS.

I have been having a lot of internal debate about the idea of running more than one service in a docker container.

Building applications in a docker.io Dockerfile is relatively simple, but sometimes you want to just install the application exactly as you would normally via already built chef cookbooks.

At DevOps Days Austin @mattray did an Openspace session on Omnibus which is a toolset based around the concept of installing an app and all of it’s prerequisites from source into a directory and then building a package ( either .deb or .rpm ) of that using

Lately I’ve been doing a lot of prototyping with Vagrant, specifically for a couple of distinct activities:- building puppet modules using the excellent puppet sandbox project and building RPM packages with FPM.

A lot of tech bloggers will write their blog posts in Markdown, convert it to HTML and paste that HTML into their blog of choice and then in the blog’s editor clean it up to suit their blog.

I’ve got an aging VMWare ESXi 4.0 server that needs to be replaced with something a little more modern and flexing.

I’m migrating from my old VMWare ESXi box to a new machine running Ubuntu 12.10 and KVM.

I have a self hosted wordpress food blog hosted on an old silly domain that I’ve wanted to move away from for a while.
