Changelog since v1.33.11

Changes by Kind

Bug or Regression

Kubeadm: during 'kubeadm init', if the default 'admin.conf' and 'super-admin.conf' paths are used, load the files, but construct in memory kubeconfigs that point to the InitConfiguration.localAPIEndpoint instead of the ClusterConfiguration.controlPlaneEndpoint. This would resolve issues with delayed load balancers which are provisioned only after the first kube-apiserver instance starts. (#138686, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: skip LocalAPIEndpoint defaulting on 'kubeadm join' for worker nodes. (#138805, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: use a dedicated ClusterRole 'system:kubelet-api-admin' for the kube-apiserver kubelet client. (#138964, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: when checking the etcd cluster status use a quorum approach, instead of considering the health of all members. This would allow the check to not fail if there are sufficient healthy voting members. (#138541, @ahrtr) [SIG Cluster Lifecycle]
