kube-apiserver无leader选举，多实例并发运行共享etcd，与controller-manager等不同。运维要点包括：滚动升级逐实例替换、处理409冲突、APF容量为各实例之和。核心flag有--etcd-servers、--etcd-servers-overrides（分集群events）、--request-timeout、--shutdown-delay-duration（需≥LB健康检查间隔×失败阈值）、--encryption-provider-config。升级顺序：etcd→apiserver→controller-manager→scheduler→kubelet，版本偏差不超过2个minor。健康检查中/readyz反映etcd连通性，/healthz不等价于etcd健康。
