How to use 'ray up' with kuberay?

Ray Clusters Kubernetes

Hi,
it seems like it should be possible to use ‘ray up’ with provider=kuberay, but i haven’t been able to make it work, nor find any documentation. The cluster config examples directory on github is also empty for kuberay.

Is there a way to use it? I would prefer to avoid writing my own adhoc cluster management scripts.

Hello! When using Kuberay, you are actually going to be using kubectl and and KubeRay specific YAML files instead of ray up, which doesn’t work with provider=kuberay. KubeRay operates on a different paradigm.

You can check these out to see if it’s helpful:

And some samples: kuberay/ray-operator/config/samples at master · ray-project/kuberay · GitHub

Hi,
thank you, I have read those docs. So kubectl ray it is.

I was a little bit confused that “ray up” uses this mapping

to dispatch. So it can apparently call into kuberay when provider=kuberay, but I haven’t been able to provide any cluster spec, and the KubeRayNodeProvider doesn’t seem provide the correct interface to be used with ray up.
