How can I find out which Ray version is installed on kuberay?

Question

Running on kind, I've installed kuberay following the docs.

I brought up the dashboard:

k port-forward svc/raycluster-heterogeneous-head-svc 8265

But this doesn't show any version information

Answer 1

You can simply run the ray --version command inside the head pod, the following did the job for me:

kubectl exec `kubectl get po |awk '{print $1}' |grep head` -- ray --version

Which returned the following for me:

ray, version 2.2.0
