    From the README

    KubeRay is a powerful, open-source Kubernetes operator that simplifies the deployment and management of Ray applications on Kubernetes. It offers several key components:

    KubeRay core: This is the official, fully-maintained component of KubeRay that provides three custom resource definitions, RayCluster, RayJob, and RayService. These resources are designed to help you run a wide range of workloads with ease.

    KubeRay ecosystem: Some optional components.

    common workflows when deploying Ray on Kubernetes. If you aren’t familiar with Kubernetes, this plugin simplifies running Ray on Kubernetes. See kubectl-plugin for more details.

    by some organizations to back user interfaces for KubeRay resource management. See KubeRay APIServer V2 for more details.

    While it is not yet production-ready, we welcome your feedback. See KubeRay Dashboard for more details.

    From September 2023, all user-facing KubeRay documentation will be hosted on the Ray documentation. The KubeRay repository only contains documentation related to the development and maintenance of KubeRay.
