GPU Service today only schedules on Kubernetes clusters; Docker / cloud
clusters can't host the CRDs. Without any awareness of that, Org
members whose Org has no K8s cluster (and no cluster_access grant on
one) saw a menu they couldn't use and a form that bottomed out with
backend errors.
Two changes lock the UX down:
- Boot probes the caller's cluster list once and stashes
hasKubernetesCluster in initialState. A new canSeeGpuService
predicate gates the menu — admins and Org owners always see it
(they can add the cluster); everyone else only sees it when a
reachable K8s cluster actually exists.
- The instances page filters its own cluster list to Kubernetes
before deciding what to show. With nothing reachable we render the
Deployments-style 'No clusters available. Add a Kubernetes cluster
to get started.' empty state and hide the create-instance CTA;
admins and Org owners additionally get the 'Add cluster' button
that jumps to cluster management.
