Kubernetes Architecture Explained: Master Node and Worker Nodes Uncovered
In a recent blog post, Kubernetes architecture was explored in detail. The post delved into the two main components that make up the system: the Master Node and the Worker Node. The Master Node is responsible for managing the cluster and coordinating tasks between nodes. It consists of key components such as the API Server, Scheduler, Controller Manager, and etcd.
On the other hand, the Worker Nodes are where applications (pods) run. Each Pod encapsulates one or more containers, and the kubelet ensures they are running smoothly. The Container Runtime manages the actual container execution, while the kube-proxy handles network rules for communication between pods and external systems.
The post highlights the importance of communication between the Master Node and Worker Nodes, which is key to maintaining a smooth-running system. It emphasizes that understanding this architecture can help developers and learners solidify their grasp of Kubernetes concepts.
