name: Kubernetes Operators
description: >-
  Kubernetes Operators are a method of packaging, deploying, and managing
  Kubernetes applications that extend the Kubernetes API to create, configure,
  and manage instances of complex applications on behalf of a Kubernetes user.

      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.

    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.

      OperatorHub.io is a community registry of Kubernetes Operators that can
      be discovered and installed via the Operator Lifecycle Manager. It
      provides a catalog of operators across categories including databases,
      monitoring, security, and networking for use in Kubernetes clusters.

      controller-runtime is a set of Go libraries for building Kubernetes
      controllers and operators. It is used by both Kubebuilder and Operator SDK
      and provides core abstractions including Manager, Client, Cache, and
      Reconciler interfaces for building controllers that interact with the
      Kubernetes API.
