- Kubeadm: remove the "ephemeral_storage" request from the etcd static pod that kubeadm deploys on stacked etcd control plane nodes. This request has caused sporadic failures on some setups due to a problem in the kubelet with cadvisor and the LocalStorageCapacityIsolation feature gate. See this issue for more details: https://github.com/kubernetes/kubernetes/issues/99305 ([#102673](https://github.com/kubernetes/kubernetes/pull/102673),...
