Pull request overview
This PR updates the kubeadm-based E2E node join flow to include kubeadm’s default bootstrap group in both the RBAC bindings and the bootstrap token’s auth-extra-groups, addressing Unauthorized errors when kubeadm E2E nodes attempt to create kubelet client CSRs.
Changes:
- Introduce a single constant for kubeadm’s default bootstrap group (
system:bootstrappers:kubeadm:default-node-token). - Add that group to all kubeadm E2E bootstrap-related RBAC subject lists alongside
system:bootstrappers:aks-flex-node. - Emit both groups in the created bootstrap token Secret via
auth-extra-groups.
