CRD Controller

A CRD (Custom Resource Definition) Controller is a component in Kubernetes that manages custom resources—specialized data types you define to extend Kubernetes' capabilities. It continuously monitors these custom resources and automates tasks such as creating, updating, or deleting related resources to ensure they are always in the desired state. Think of it like a personalized manager that keeps your custom applications or configurations running smoothly, making complex or unique setups easier to handle within the Kubernetes ecosystem.
