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 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...
