Work node communicates with management node through kubelet service to manage the life cycle of container and communicate with other nodes in cluster. It provides computing resources for container and Pod. Work node is the node that runs Pod in Kubernetes cluster architecture. It is also an entry process for cluster control Kubernetes Controller Manager is the automation control center for all resource objects in Kubernetes Kubernetes Schedule is the process responsible for resource scheduling (Pod scheduling).

It is the only access to add, delete, change, search and other operations of all resources in Kubernetes. Kubernetes API server provides the key service process of HTTP Rest interface. It has Etcd storage service (optional), runs Api Server process, Controller Manager service process and Scheduler service process, and associates working node Node. K8s cluster management node is responsible for the management of the cluster, providing access to cluster resources and data. Kubernetes Architecture and Components There are two types of K8S cluster: management node and working node. It is not only a container layout tool, but also a new distributed architecture leading scheme based on container technology. It can realize automatic deployment, automatic expansion and maintenance of container clusters. Kubernetes can easily manage container applications running across machines. It provides application deployment, maintenance, extension mechanism and other functions. Kubernetes is an open source container cluster management system of Google (Borg).
