Can'；t修改Kubernetes静态吊舱的ETCD清单

我想将etcd pod修改为侦听0.0.0.0（或主机IP），而不是127.0.0.1

我正在进行从单主机到多主机kubernetes群集的迁移，但我遇到了一个问题，在使用正确的设置修改/etc/kubernetes/manifests/etcd.yaml并重新启动kubelet甚至docker守护进程后，etcd仍在127.0.0.1上工作

在docker容器中，我看到etcd以--listen client url=而不是主机IP开始

cat/etc/kubernetes/manifests/etcd.yaml

首先检查kubelet选项--pod清单路径，将正确的yaml放入该路径

要确保已删除

etcd

pod，请将yaml文件移出

pod清单路径

，等待该pod已被

docker ps-a

删除。然后将正确的yaml文件放入

逐步查看我的自动化脚本，发现我已在扩展名为.bak的同一文件夹中执行了etcd yaml备份。看起来kubelet daemon会上载清单文件夹中的所有文件，而不管文件扩展名如何

请发布您正在使用的清单嗨，@jaxxstorm在上面的帖子中添加了etcd.yaml清单内容和运行pod yamlh的片段奇怪的是，当我上次手动执行此过程时，一切都很好，我成功地将etcd成员加入集群。但是现在我无法使用主机IPTM远程登录etcd。在做了更改后，你是否杀死了pod？是的，我也删除了pod和docker容器，重新启动了docker和kubelet守护进程，甚至重新启动了主节点，但仍然是相同的请发布你正在使用的清单HI，@jaxxstorm在上面的帖子中添加了etcd.yaml清单内容和运行pod yamlh的片段奇怪的是，当我上次手动执行此过程时，一切正常，我成功地将etcd成员加入集群。但是现在我无法使用主机IPD远程登录etcd。在做了更改后，你是否杀死了pod？是的，我也删除了pod和docker容器，重新启动了docker和kubelet守护进程，甚至重新启动了主节点，但仍然是sameHi@menya，我甚至将
