question: installation requirements, k8s admin vs user

[MEllis-github]

question

In the code linked, if kube_pod_manager == ray and kube_pod_manager_non_root == true, then a k8s admin or super user needs to install a namespaced or clusterwide ray operator and the raycluster crd for the user for this to function, is that correct? If so, where is this documented, or where should it be documented relative to the existing org/repo structure?

  	# user does not have root access to their kubernetes cluster

  	else

KUBE_POD_MANAGER_NON_ROOT applies to any situation where we don't want to assume root access. Currently, this applies to the "keep it simple" and "my admin will install mcad" paths.

re: how we document this, good question. i'll need to cogitate.
