The Operator Framework is a set of developer tools and Kubernetes components, that aid in Operator development and central management on a multi-tenant cluster.
Software development kit for building Kubernetes applications. Provides high level APIs, useful abstractions, and project scaffolding.
Build an OperatorManagement framework for extending Kubernetes with Operators. Helps install, update, and manage the lifecycle of Operators running across clusters.
Install OLMHome for the Kubernetes community to share Operators. Provides a catalog of existing Operators and guidance for contributing new Operators.
Contribute an OperatorThe goal of an Operator is to put operational knowledge into software. Previously this knowledge only resided in the minds of administrators, various combinations of shell scripts or automation software like Ansible. It was outside of your Kubernetes cluster and hard to integrate. With Operators, CoreOS changed that.
Operators implement and automate common Day-1 (installation, configuration, etc.) and Day-2 (re-configuration, update, backup, failover, restore, etc.) activities in a piece of software running inside your Kubernetes cluster, by integrating natively with Kubernetes concepts and APIs. We call this a Kubernetes-native application. With Operators you can stop treating an application as a collectionof primitives like Pods, Deployments, Services or ConfigMaps, but instead as a single object that only exposes the knobs that make sense for the application.
Learn more about OperatorsThe Operator Framework and its components are open source, so please feel encouraged to jump into each individually and learn what else you can do.
