#### What is Kubernetes Operator?

> A Kubernetes operator is an application-specific controller that extends the functionality of the Kubernetes API to create, configure, and manage instances of complex applications on behalf of a Kubernetes user. - [What is a Kubernetes operator?](https://www.redhat.com/en/topics/containers/what-is-a-kubernetes-operator#:~:text=A%20Kubernetes%20operator%20is%20an,behalf%20of%20a%20Kubernetes%20user).
