Nodes

Feature Overview​

A node is a worker node in a Kubernetes cluster. It may be a virtual or physical machine. kubelet, a Kubernetes agent, runs on each node to manage the lifecycle of containers.

Applicable Scenarios​

Containerized applications are running on nodes. You can add or remove nodes to scale up or down computing resources in a cluster.

Supported Capabilities​

A node provides computing and storage resources, enabling it to run containers and deliver services.

Highlights​

Nodes can be categorized and selected using labels and selectors, allowing flexible application deployment and scheduling.

Implementation Principles​

A worker node communicates with the master node to receive management instructions of the cluster and report its status.

Nodes act as computing resource providers in a Kubernetes cluster. They are responsible for running and managing pods, ReplicaSets, Deployments, Services, and resources related to persistent storage. Scheduling and management mechanisms govern the relationship between nodes and these resources, ensuring that they run on suitable nodes and can communicate with each other.
