🚀 Kubernetes day19 | RBAC Explained | ServiceAccount, ClusterRole & ClusterRoleBinding with a Demo

🚀 In this video, we will understand Kubernetes RBAC concepts with a real-time monitoring use case using Prometheus and Node Exporter. We will cover: ✅ What is a ServiceAccount in Kubernetes ✅ Why applications use ServiceAccounts instead of human credentials ✅ Difference between Role/RoleBinding and ClusterRole/ClusterRoleBinding ✅ Authentication vs Authorization in Kubernetes ✅ How ClusterRoleBinding works internally ✅ Real-time monitoring use case using Prometheus ✅ Deploying Node Exporter as DaemonSet ✅ Accessing node-level metrics from /metrics endpoint ✅ End-to-end RBAC setup demonstration 📌 Real-Time Scenario: Prometheus needs cluster-wide access to monitor node metrics like CPU, memory, filesystem, and network utilization. Since nodes are cluster-scoped resources, we use ClusterRole and ClusterRoleBinding with ServiceAccount for secure authentication and authorization. 📂 GitHub Repository: Kubernetes Playlist GitHub Repo 💡 Topics Covered: Kubernetes RBAC ServiceAccount ClusterRole ClusterRoleBinding Authentication & Authorization Prometheus Monitoring Node Exporter Kubernetes Security Best Practices Least Privilege Principle 👍 If you found this helpful: ✔ Like ✔ Share ✔ Subscribe 🔔 Stay tuned for more Kubernetes, DevOps, Docker, Jenkins, OpenShift, Helm, ArgoCD, and CI/CD content. #Kubernetes #DevOps #RBAC #Prometheus #ServiceAccount #ClusterRole #ClusterRoleBinding #NodeExporter #Monitoring #K8s
