In part 1 I covered k6's philosophy and the anatomy of a first test. This post is where things get real — a production-grade test suite running against a live microservices app on a homelab Kubernetes cluster, including what went wrong on the first run and how I debugged it.

We recently migrated our production GKE cluster from the traditional Ingress controller to the Kubernetes Gateway API — and honestly, we should have done it sooner.

This article shares our experience of getting rid of continuously running EC2 instances, setting up scalable GitLab Runners in AWS, and significantly cutting CI infrastructure costs.

IPMan is a Kubernetes operator that simplifies the management of IPSec connections, enabling secure communication between your Kubernetes workloads and the outside world.

Klarity is an open-source, enterprise-grade Kubernetes observability dashboard built for teams that follow GitOps practices.

Kstack is a skill pack for Claude Code that helps you perform monitoring, troubleshooting and auditing tasks on your K8s clusters in a smart and efficient way.

The k8s-overcommit Operator is a Kubernetes operator designed to intelligently manage resource overcommit on pod resource requests. It automatically adjusts CPU and memory requests based on configurable overcommit classes, enabling better cluster resource utilization while maintaining workload performance.

What doesn't usually happen is anyone asking: what if she hadn't been there? Because that heroic save, for all the heartfelt celebration around it, was actually a near miss from a systemic point of view.

In this post I want to discuss how we organize systems by contrasting two families of approaches. The first is about analytical decomposition that aims to maintain control over a system, and the other is based on a perspective of complex systems that resist analysis, which tend to focus on figuring out interactions and mechanisms to foster desirable emergent behaviour.

Pilots have a specific term for moving from one airplane to another: a "type conversion". Not "learning to fly" again — you already know how to fly. It's the process of taking everything you already know and re-mapping it onto a new machine that does the same job with a different cockpit. Starting a new SRE job is the same thing.

At the end of last year, our uptime was pretty shaky. Many of these outages were caused by a single bug, deep in SQLite. It took months of intense forensics to track it down.
