etcd成员没有leader
Etcd member has no leader
我是 Kubernetes 的新手，目前正在 CentOS 7 上设置 Kubernetes 集群，其中包含 1 个主节点和 2 个小节点。我正在遵循位于 here.
的 Kubernetes 官方设置指南
我根据文档配置了 etcd，然后 运行
etcdctl mkdir /kube-centos/network
我收到以下错误
Error: client: etcd member http://0.0.0.0:2379 has no leader
谁能帮我解决这个问题？我整天都在里面，但我还没有头绪。
下面提供etcd.conf和flanneld配置文件供参考：
** etcd.conf **

非常感谢您的帮助！

我强烈建议你试一试。那个实际上适用于 CentOS 7。没问题。
