你的活着的master的ip apiserver.cluster.local kubelet的端口占用 Port 10250 is in use kubelet还活着。kubeadm join时会启动kubelet 使用kubeadm reset 重置配置 etcd目录不为空 [ERROR DirAvailable--var-lib-etcd]: /var/lib/etcd is not empty 删除即可。
RemovePodsViolatingNodeAffinity 此策略会确保那些违反 node 亲和性的 pod 被驱逐。比如 podA 运行在 nodeA 上,后来该节点不再满足 podA 的 node 亲和性要求,如果此时存在 nodeB 满足这一要求,则 podA 会被驱逐到 nodeB 节点上。 遵循机制 当Descheduler 调度器决定于驱逐 pod 时,它将遵循下面的机制: ...
IP就是kubectl get node -o wide的IP，token在cat /var/lib/rancher/k3s/server/node-token中。
