Operator Framework is a set of open-source tools that simplifies building and managing the lifecycle of Kubernetes operators. The Kubernetes operator pattern, originally introduced by CoreOS, is an approach to encapsulate the knowledge of operating an application using Kubernetes native capabilities; it includes resources to be managed and controller code that ensures the resources are matching their target state. This approach has been used to extend Kubernetes to manage many applications, particularly the stateful ones, natively. Operator Framework has three components: Operator SDK, which simplifies building, testing and packaging Kubernetes operators; Operator lifecycle manager to install, manage and upgrade the operators; and a catalog to publish and share third-party operators. Our teams have found Operator SDK particularly powerful in rapidly developing Kubernetes-native applications.
