In this video, you will learn about the following topics:
1. Setting up a minikube cluster on your local machine.
2. Deploying a simple Prometheus server inside Kubernetes.
3. Creating a role-based access control (RBAC) for Prometheus inside Kubernetes.
4. Deploying a simple node-exporter application inside Kubernetes for monitoring the individual nodes of a Kubernetes cluster.
5. How to add the node-exporter as the "target system to be monitored" to the Prometheus.
6. Deploying a simple Grafana server inside Kubernetes.
7. How to add prometheus as a data source to Grafana.
8. Creating dashboards for the node-exporter via the Grafana UI.
