Deep Dive into Kubernetes Components

Explore in-depth insights into Kubernetes core components, their roles, architecture, and best practices.

Kubernetes Deep Dive

Learn how Kubernetes works under the hood by exploring key control plane and worker node components in detail. This series covers the critical elements of Kubernetes architecture, troubleshooting guides, and best practices.

Control Plane Components

• Kube-API Server - The gateway to Kubernetes, handling all API requests and authentication.
• Kube Controller Manager - Manages controllers that regulate the cluster state.
• Kube Scheduler - Assigns workloads to nodes based on resource availability and scheduling policies.
• etcd - A distributed key-value store for cluster state and configuration.

Node Components

• Kubelet - The agent responsible for managing container execution on a node.
• Kube Proxy - Maintains network rules and service discovery.
• Containerd - A container runtime that runs and manages container lifecycles.

Storage and Networking

• Cloud Controllers - Integrate Kubernetes with cloud providers for storage, networking, and load balancing.
• Cluster DNS (CoreDNS) - Handles internal DNS resolution for services and pods.
• CSI Driver - Manages storage provisioning and volume attachments.
• Kubectl - The command-line tool for interacting with Kubernetes.
