I want to run Kubernetes on amd64 hardware. I already own two Raspberry PIs, but I always struggle with ARM and the need to create custom Docker images. This post explains how to run a single-node Kubernetes (K3s) on the PC Engines APU2 board with an embedded AMD CPU.
KubeCon EU happened in Barcelona this year (May 20 - 23). This is my personal conference recap. I will not talk about any of the official KubeCon announcements (as there are enough other places to read about them).
Kubernetes has its virtues and is worth investing in, but it is undoubtedly complex and comes with many operational challenges. We faced many of them on our journey towards "cloud native" at Zalando.
As a reply to Zalando's "Running 80+ clusters in production" post, someone asked whether this (80+ clusters) would not defeat "the purpose"? My answer would not fit in a Tweet, so here it is as a blog post.
The Accelerate book is about "measuring software delivery performance — and what drives it — using four years of groundbreaking research and rigorous statistical methods". I'll try to explain why I see the book as a blueprint for platform teams and how it relates to developer experience.
There was a recent blog post by Matthias Endler on why you might not need Kubernetes. I'll try to explain why I believe Kubernetes is worth a close look, even if you just want to run some containers.
I posted my previous blog post about Kubernetes failure stories on Hacker News (HN) last Sunday, exactly one week ago. Here is what happened afterwards.
I started to compile a list of public failure/horror stories related to Kubernetes. It should make it easier for people tasked with operations to find outage reports to learn from.
This is a small report of what I observed after one month of using the Kubernetes Vertical Pod Autoscaler (VPA) for a simple application (only a single pod).
I'm currently reading the book "Black Swan" by Nassim Nicholas Taleb. That led me to the realization that we deal with a lot of Black Swan events in technology.
