k8s operator

A Kubernetes (k8s) operator is a piece of software that automates the management of complex stateful applications on Kubernetes clusters. It is a custom controller that extends the Kubernetes API to manage and automate the deployment, scaling, and operations of applications.

Operators use custom resources and controllers to define application-specific behavior and automate complex tasks, such as backups, upgrades, and scaling. They can also provide self-healing capabilities by monitoring and responding to changes in the application state.

Operators are typically developed by software vendors or open-source communities to simplify the deployment and management of their applications on Kubernetes. They are designed to reduce the operational burden on developers and operators by automating many of the manual tasks required to manage complex applications.
