kube-apiserver: Error: --etcd-servers must be specified

启动 kube-apiserver 失败，

查看状态：

systemctl status kube-apiserver

cat /var/log/messages|grep kube-apiserver|grep -i error

 

 

提示：Error: --etcd-servers must be specified

kube-apiserver.conf 也有配置  --etcd-servers 服务器列表, 可能kube-apiserver.conf格式有问题：

查看配置：

cat /usr/local/kubernetes/cfg/kube-apiserver.conf

多次尝试之后发现问题，kube-apiserver.conf 文件的每一行后面多个了空格，去掉就可以了：（注：必须每一行的末尾空格都要去掉，有一个都会报上面的错误）

 

 去除空格之后重新启动，状态如图：
