The Kubernetes Security Policy I Can't Accidentally Delete (And Why That Matters)

Last month, I was helping a client recover from what should have been a routine cluster upgrade. Their platform team had defined ValidatingAdmissionPolicies to enforce image registries and prevent privileged containers. Good security posture. But somewhere in the chaos of a botch...

DRA Finally Grew Up: Why I'm Actually Excited About Kubernetes Resource Management Again

I spent three hours last week debugging why a GPU pod kept getting scheduled on a node that didn't have the accelerator it requested. The pod would sit there pending, the logs were useless, and I had to ssh into the cluster to inspect the actual driver state manually. It was the...

Storage in Kubernetes Stopped Being An Afterthought, and That Changes Everything

I remember the exact moment I realized Kubernetes storage was becoming a real problem at work. We had a containerized PostgreSQL instance running in production, and a developer asked the most innocent question: "Can we take a snapshot of just this database without shutting it dow...

Finally, a Way to Snapshot Multiple Volumes Without Losing Your Mind

I remember the exact moment this problem bit me hard. We were running a multi-tier application on Kubernetes with data spread across three volumes—one for the database, one for logs, and one for cache metadata. A customer asked for a point-in-time recovery, and we had to quiesce...

Stop Guessing Why Your Kubernetes Cluster Is Slow: PSI Metrics Finally Tell the Real Story

I spent three hours last month debugging why a client's Kubernetes cluster was dropping requests during peak load. CPU utilization was at 60%. Memory at 45%. Everything looked fine on the dashboards. But their users were experiencing 10-second latencies on p95. I was looking at t...

Why Kubernetes v1.36 Finally Made Me Stop Dreading Batch Job Scheduling

I spent three hours last Tuesday debugging why our ML training pipeline kept deadlocking on Kubernetes. Four worker pods needed to run simultaneously, but the scheduler was placing them on different nodes at different times, and once the third one landed, there wasn't enough memo...

etcd 3.7 Finally Fixes the Problem I've Been Hacking Around For Years

I remember the exact moment I realized etcd's limitation was killing our query performance. We were building a service that needed to fetch thousands of configuration entries from etcd, and every single request would block until the entire result set was assembled in memory. On a...

Why Kubernetes Just Made My Vulnerability Scanner Useless (And That's Actually Good)

I was running a security audit on one of our staging clusters last month when something weird happened. My vulnerability scanner—the expensive one we pay good money for—suddenly flagged three CVEs across all our Kubernetes nodes as *fixed*, even though our security team kept insi...

Why I Finally Stopped Fighting Kubernetes UIs (and Why You Should Care)

Last year, I was debugging a pod crash in production at 11 PM and found myself switching between the Kubernetes Dashboard and kubectl because the Dashboard couldn't show me the full picture across our two clusters. I remember thinking: "This tool was fine when we had one cluster...

Kubernetes v1.36 Made Me Rethink How We Authorize Kubelet Access

I was debugging a monitoring issue at 2 AM last week when it hit me: we'd granted our observability stack permissions that were way too broad on the kubelet API. The permission model was essentially "here, have access to everything kubelet-related" because we needed visibility in...
