Kubernetes, Monitoring with Prometheus and Grafana
summary
A step-by-step demo that deploys a sample containerized app to a Kubernetes cluster on Google Cloud, installs Prometheus using the Prometheus Operator, and exposes Prometheus on port 9090 and Grafana on port 3000. It configures Alertmanager and exporters, uses Docker images and manifests from a provided repo, and shows Grafana dashboards with live metrics (CPU, memory, request counters, histograms) and alerts firing during the demo.
