Node

Meaning in software engineering, with examples

/noʊd/nounCore term

In software engineering, node means: One machine, physical or virtual, that is part of a cluster. In Kubernetes, worker nodes are the machines where pods actually run.

In Turkish: düğüm, node

How it is used

Nodes are added, drained (emptied of pods before maintenance), cordoned and removed. A 'node pool' or 'node group' is a set of nodes with the same machine type. Do not confuse it with Node.js.

Example sentences

  1. One node ran out of memory, and Kubernetes moved its pods to the others.

  2. Drain the node before you patch it, otherwise users will see errors.
