About

I’m Divyam Azad, a DevOps engineer in Pune, India. Six years in, my days are Kubernetes clusters and bare-metal fleets, infrastructure as code, GitOps pipelines, zero-trust networking and observability — and, increasingly, the quiet discipline of keeping small systems honest. I started out in ethical hacking, which still shapes how I build things: assume an adversary, keep the surface small, and make the evidence public.

What this blog is

Notes from running real infrastructure — mostly the small server behind this site. It hosts the portfolio, a status page, a Telegram bot a household actually uses, CrowdSec in front of the edge, and a self-hosted NetBird control plane, all declared in one git repository and converged by a five-minute pull loop. When something breaks or surprises me, it becomes a post: what happened, why, and the smallest fix that actually works.

Expect: GitOps on one box, Docker and Caddy edge cases, security you can verify from the outside, Kubernetes and cluster lifecycle, and the occasional write-up of an outage I caused myself. Don’t expect: vendor pitches, listicles, or “ultimate guides”.
