CRD (Custom Resource Definition)

A Custom Resource Definition (CRD) is a way to extend a Kubernetes system by allowing users to create their own types of resources tailored to specific needs. Think of it as adding a new form or category to what Kubernetes manages, beyond its standard objects like pods or services. This customization enables organizations to define and manage complex applications and configurations more efficiently, integrating proprietary or specialized resources directly into the Kubernetes ecosystem. Essentially, CRDs give you the power to build and operate your unique applications within Kubernetes, making the platform more flexible and adaptable to your specific requirements.
