  Kubernetes Architecture Deep Dive: Understanding the Control Plane and Data Plane 📅 Published: August 2026 ⏱️ Estimated Reading Time: 18 minutes 🏷️ Tags: Kubernetes Architecture, Control Plane, Data Plane, kube-apiserver, etcd, kube-scheduler, kube-controller-manager Introduction: Beyond the Basics Kubernetes is a complex, distributed system with a well-defined architecture. Understanding the components, their roles, and how they interact is fundamental for designing, debugging, and optimizing your clusters. This guide is a deep dive into the Kubernetes architecture, covering the control plane and the data plane (worker nodes). We’ll explain the purpose of each component and how they collaborate to maintain the desired state of your applications. Part 1: The Kubernetes Control Plane The control plane is the brain of the cluster. It is a collection of components that make global decisions about the cluster (e.g., scheduling), detect and respond to cluster events (e.g., restartin...

  DaemonSets: Running System Services on Every Node 📅 Published: August 2026 ⏱️ Estimated Reading Time: 12 minutes 🏷️ Tags: Kubernetes, DaemonSets, System Services, Node Monitoring, DevOps Introduction: What is a DaemonSet? A DaemonSet is a Kubernetes controller that ensures a copy of a Pod runs on every node in your cluster. When you add a new node, the DaemonSet automatically deploys the Pod on that node. When you remove a node, the Pod is garbage collected. Think of a DaemonSet as a "node daemon manager." It runs background services that need to be present on every node, such as monitoring agents, log collectors, or network proxies. Key characteristics: Runs one Pod per node : Exactly one Pod per eligible node Auto-scaling : New nodes get the Pod automatically Auto-healing : Pods are recreated if they fail Node selection : Can run on specific nodes using nodeSelectors, tolerations, and affinities Part 1: Why Use DaemonSets? Common DaemonSet Use Cases Monitoring and Obse...
