![]() When an application is deployed to the cluster, Kubernetes distributes the work across the nodes. Instead of managing specific physical or virtual machines, you can treat each node as pooled CPU and RAM resources on which you can run containerized workloads. Kubernetes Nodes vs PodsĪ Kubernetes node is a single machine in a cluster that serves as an abstraction. This is part of an extensive series of guides about microservices. Kubernetes nodes are used by organizations to run a variety of workloads, as a core component in modern DevOps processes. Each node runs the kubelet-an agent that enables the Kubernetes control plane to control the node. Worker nodes-these are nodes on which you can run containerized workloads.Components of the master node include the API Server, etcd (a database holding the cluster state), Controller Manager, and Scheduler. A cluster must have at least one master node there may be two or more for redundancy. The Kubernetes Master node-runs the Kubernetes control plane which controls the entire cluster.A Kubernetes cluster can have a large number of nodes-recent versions support up to 5,000 nodes. A node can be a physical machine or a virtual machine, and can be hosted on-premises or in the cloud.
