Take the notes app from "it ships" to production-grade: resilient, secure, observable, and self-deploying.
For graduates of the beginner course. Hands-on on a real multi-node cluster — free, with k3d.
Prerequisite: finish the DevOps Lab (beginner course) first — especially Docker, Kubernetes, CI/CD, IaC, and Monitoring. This track assumes you can already build an image, write a Deployment, and run a pipeline. We pick up the same notes app and harden it toward production.
Each module hardens or scales the same project. One concept at a time, on a real multi-node cluster. Every module = a written tutorial + a hands-on lab + a cheat sheet.
Same rhythm as the beginner course — learn the concept, do a hands-on lab, keep a cheat sheet — but everything runs on a real multi-node Kubernetes cluster you create locally with k3d (k3s in Docker). That means autoscaling, scheduling, service mesh, and chaos experiments behave like the real thing, while staying completely free. The same notes app grows into a small, production-grade microservices platform you can put on a senior résumé. Cloud equivalents are noted throughout so the skills transfer to AWS, GCP, or Azure.
