kubernetes - 重置 kubeadm 后无法删除 etcd

Question

当我尝试 kubeadm reset -f ，提示无法删除etcd服务器，必须手动删除。

failed to remove etcd member: error syncing endpoints with etc: etcdclient: no available endpoints. Please manually remove this etcd member using etcdctl

Answer 1

这是控制平面(主)节点吗？
如果不是:只需运行 kubectl delete node <node_id>应该足够了(见下面的引用)。这将更新 etcd 并处理其余的清理工作。如果您希望重新添加它，您仍然必须首先诊断导致节点无法重置的原因……但这是一个单独的问题。参见讨论，例如，here关于一个相关问题:

If the node is hard failed and you cannot call kubeadm reset on it, it requires manual steps. you'd have to:

1. Remove the control-plane IP from the kubeadm-config CM ClusterStatus

2. Remove the etcd member using etcdctl

3. Delete the Node object using kubectl (if you don't want the Node around anymore)

1 and 2 apply only to control-plane nodes.

希望这会有所帮助 - 如果您正在处理主节点，我很乐意包含要运行哪些命令的示例。
