A specialized controller used to manage a custom resource
|
|
The operator pattern is a system design that links a {{< glossary_tooltip term_id="controller" >}} to one or more custom resources.
You can extend Kubernetes by adding controllers to your cluster, beyond the built-in controllers that come as part of Kubernetes itself.
If a running application acts as a controller and has API access to carry out tasks against a custom resource that's defined in the control plane, that's an example of the Operator pattern.
