Advent of Code - Day 2

Day 2, another day, another challenge. Part 1 Here’s the challenge: --- Day 2: Cube Conundrum --- You're launched high into the atmosphere! The apex of your trajectory just barely reaches the surface of a large island floating in the sky. You gently land in a fluffy pile of leaves. It's quite cold, but you don't see much snow. An Elf runs over to greet you. The Elf explains that you've arrived at Snow Island and apologizes for the lack of snow. [Read More]

Advent of Code - Day 1

It’s the time of year again where you come together and… DO CODE CHALLENGEEEEEES! Yes, Advent of Code is basically happening every year. With 24 cool challenges, in this case actually more, as we will find out. So I thought, why not get some coding done and then write a little thing about it. Actually, I got hooked by Polar Signal’s “Let’s Profile”, so kudos go there. I think it’s probably needless to say ,but I don’t, wouldn’t and can’t claim that my solutions are the best or fastest or whatever. [Read More]

Starting a new conference

because what could possibly go wrong?!

A while ago, there as a little bit of a conversation happening on Twitter, that was sparked by Matthias’s statement that more and more meetups are happening again. Now only a short year later, I felt like it was time. The time to actually follow through and start a new conference. In case you haven’t seen it yet: SkySummit This is a new thing. I mean, sure, I’ve organised a handful of concerts when I was in my early 20s, but I’m not sure that’s comparable. [Read More]

Writing a Container Platform - Part 3

Repo me

This one will be a little shorter, but still something worth talking about: how to set up the repo. I know, I know: “Just click the button”. That’s not really what I mean. It is more about everything I like to have in repo. Community standards License The license topic has gotten pretty hot recently with a bunch of OSS projects moving to very interesting forms of licensing be it SSPL like Elastic and MongoDB haven chosen to or AGPL like Grafana.

Writing a Container Platform - Part 2

APIs and containers

Time to get going. First things first: we need to create a repository and initialize it. GitHub is the easy choice here, but also just as good as any other option right now. We follow the documentation to create ourselves a nice organisation so just in case this is actually going to be cool, the whole thing doesn’t just live in my personal space. Really, when you consider making something cool that might have an open source community in the future, keep it out of your personal space. [Read More]

Writing a Container Platform - Part 1

The Foundation

After spending a lot of time on Stack Overflow recently, a thought started pestering my brain: why is Kubernetes so complicated? This was followed by “Can I build something simpler?”, and so here we are, building our own Container Platform from scratch. Platform engineering is super hot right now so let’s have our own go at it. At the end of the whole thing, you will find the whole result oin GitHub, Open Source of course. [Read More]

Minikube and the image architecture

From stack overflow into a rabbit hole

Recently I’ve been trying to answer some more questions on stack overflow. For one to be a better member of the community but on the other hand also because I’ve been somewhat interested in joining the Docker Captain’s program and there are some requirements around activity, but that’s a story for a different day. Anyhow, after a lot of more or less simple questions, I landed at a super cool one. [Read More]

CodeReady Containers & Apple Silicon

No OpenShift for Apple Silicon users

Before you dive deep: This will not give you a working local OpenShift on Apple Silicon but a working CRC using Podman. At the very end of my last post I briefly mentioned that CodeReady Containers(CRC) were not available for Apple Silicon. Literally two hours later I came across a GitHub Issue that’s functions as an epic ticket for CRC support on M1 and guess what? There’s a new comment hinting to a dev preview version. [Read More]

Openshift and Apple Silicon

the pains of an M1 user

After receiving my new M1 powered MacBooks Pro I was happy. Very happy. After all, it was quite the upgrade from the shabby Intel I5 powered MacBook Pro that I was running while still working at Red Hat. Everything is so blazing fast now, and it just feels nice. While I was aware that not all CLI tools have yet been cross-compiled for ARM, I had a tiny “what the fuk” moment when I wanted to get the work on the “Operating OpenShift” book going and found out that basically none of the tooling was ready for Apple Silicon.

Deploying A Blog With GitHub Actions - Part 1

As the title is hinting, this is part one of a series of entries to follow. This first post will deal with a topic that I personally have to touch on a lot: Deploying to Cloud Run. Why? This very blog you’re reading right now is deployed precisely that way. In this article, we’re going to walk through a couple of simple steps to get a hugo based blog (or anything more or less) deployed to Google Cloud Run using GitHub Actions. [Read More]
