Cluster - CI/CD Glossary Definition

A cluster is a control plane plus its worker nodes, managed as one unit that schedules your containers.

A cluster is the set of worker nodes plus a control plane managed together as one orchestration unit, presenting a single API to schedule and run containerized workloads.

Deploy stages target a specific cluster (or several). Knowing the control-plane and node split clarifies where a deploy command actually lands.

Control plane vs nodes

The control plane holds the API server, scheduler, and controllers; nodes run your pods. CI credentials usually authenticate to the API server to apply changes.
