Ray Cluster

Make sure ray-operator has been deployed.

Ray is an open source framework that provides a simple, universal API for building distributed applications. Ray is packaged with RLlib, a scalable reinforcement learning library, and Tune, a scalable hyperparameter tuning library.

Helm

$ helm version
version.BuildInfo{Version:"v3.6.2", GitCommit:"ee407bdf364942bcb8e8c665f82e15aa28009b71", GitTreeState:"dirty", GoVersion:"go1.16.5"}

TL;DR;

helm install ray-cluster . --values values.yaml --namespace ray-system --create-namespace

Installing the Chart

To install the chart with the release name my-release:

helm install my-release . --values values.yaml --namespace ray-system --create-namespace

note: The chart will submit a RayCluster.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release -n ray-system

The command removes nearly all the Kubernetes components associated with the chart and deletes the release.

Check Cluster status
