  description: Kubernetes Operators extend the Kubernetes API for managing complex stateful applications using custom resources
    and controllers. An Operator encodes the operational knowledge of a domain expert into software that automates the deployment,
    scaling, and management of Kubernetes applications.

  name: Kubernetes Custom Resource Definitions
  description: The CustomResourceDefinition (CRD) API lets you extend the Kubernetes API by defining new resource types with
    custom schemas. When a CRD is created, the Kubernetes API server automatically serves and handles storage for the new
    custom resource, enabling operators and other controllers to manage domain-specific objects.

  description: The Operator SDK is a framework for building Kubernetes Operators in Go, Ansible, or Helm. It provides high-level
    APIs, abstractions, scaffolding tools, and CLI commands that simplify writing operator logic and integrating with the
    Operator Lifecycle Manager (OLM) for packaging and distribution.

  description: The Operator Lifecycle Manager (OLM) extends Kubernetes with a declarative API for installing, upgrading, and
    managing the lifecycle of Operators and their dependencies in a cluster. OLM provides cluster administrators with fine-grained
    control over what operators are available and which namespaces they can operate in.
