containers - etcd成员没有leader

Question

我是 Kubernetes 新手，目前在 CentOS 7 上设置 Kubernetes 集群，其中包含 1 个 master 和 2 个 minions。我正在关注位于 here 的 Kubernetes 官方设置指南.

我根据文档配置了 etcd，并且在我运行之后

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

谁能帮我这个？我花了一整天的时间，但我还不知道。

下面提供 etcd.conf 和 flanneld 配置文件供引用:

** etcd.conf **

下面是小黄人上的法兰绒配置

# Flanneld configuration options

# etcd url location.  Point this to the server where etcd runs
FLANNEL_ETCD_ENDPOINTS="http://node1:2379"

# etcd config key.  This is the configuration key that flannel queries
# For address range assignment
FLANNEL_ETCD_PREFIX="/atomic.io/network"

# Any additional options that you want to pass
#FLANNEL_OPTIONS=""

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。没有汗水。
