The worker node(s) host the {{< glossary_tooltip text="Pods" term_id="pod" >}} that are
|
|
|
|
|
the components of the application workload. The
|
|
|
|
|
{{< glossary_tooltip text="control plane" term_id="control-plane" >}} manages the worker
|
|
|
|
|
nodes and the Pods in the cluster. In production environments, the control plane usually
|
|
|
|
|
runs across multiple computers and a cluster usually runs multiple nodes, providing
|
|
|
|
|
fault-tolerance and high availability.
