Kubernetes Control Plane consists of a collection of below processes on your cluster: Master components provide the cluster’s control plane. End users can also use the API directly to interact with the cluster. The nodes communicate with the master using the Kubernetes API, which the master exposes.The master schedules the containers to run on the cluster’s nodes. When any applications need to be deployed on Kubernetes, master issues command to start the application containers.The node should also have tools for handling container operations, such as Docker or rkt. Each node has a Kubelet, which is an agent for managing the node and communicating with the master. Each Node can be a VM or a physical computer that serves as a worker machine in a cluster.The Master coordinates all activities in your cluster, such as scheduling applications, maintaining applications’ desired state, scaling applications, and rolling out new updates etc.,.Node are the workers nodes that runs applications.Any cluster (example below) would have two types of resources:.To interact, there is an API layer exposed, same can be interacted using command-line interface via kubectl.Kubernetes automates the entire distribution and scheduling of application containers across a cluster in a more efficient way. Kubernetes Architecture: Key Components and Abstractionsįollowing would help you to learn about the different parts of the Kubernetes system and the abstractions. Self-healing: auto-placement, auto-restart, auto-replication, auto-scaling.Extensible: modular, pluggable, hook able, composable.Portable: public, private, hybrid, multi-cloud.

The abstractions in Kubernetes allow you to deploy containerized applications to a cluster without tying them specifically to individual machines. Kubernetes coordinates a highly available cluster of computers that are connected to work as a single unit. It is designed to automate deploying, scaling and operating application containers. Kubernetes is a production-ready, open source platform designed with Google’s accumulated experience in container orchestration, combined with best-of-breed ideas from the community.
