Prometheus Metrics Overview
Even without cloud budget or large infra, you can demonstrate DevOps readiness through local deployment labs. This lab shows:
- Helm-based production installs
- Working Kubernetes setup (Minikube/K3s)
- Real monitoring with Grafana + Prometheus
- Documentation-first and CI-driven development
