Docker [kubeadm]更新cni配置时出错

尝试使用命令“kubeadm init”设置集群时，我在/var/log/messages中收到错误消息：

我的Linux版本是：

[root@master ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core) 

[root@master ~]# docker -v
Docker version 1.12.5, build 7392c3b

Docker版本为：

[root@master ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core) 

[root@master ~]# docker -v
Docker version 1.12.5, build 7392c3b

Kubernetes版本：

[root@master ~]# kubeadm version
kubeadm version: version.Info{Major:"1", Minor:"6+", GitVersion:"v1.6.0-alpha.0.2074+a092d8e0f95f52", GitCommit:"a092d8e0f95f5200f7ae2cba45c75ab42da36537", GitTreeState:"clean", BuildDate:"2016-12-13T17:03:18Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}

docker容器：

CNI已经安装好了：

[root@master ~]# yum list |grep kubernetes-cni.x86_64 
kubernetes-cni.x86_64                      0.3.0.1-0.07a8a2            @kubernetes

有人面临类似的问题吗？

你只需要安装一个第三方Pod网络，就像指南中所说的那样

就我个人而言，我使用的是编织或法兰绒。例如，您可以通过以下方式安装Weave：

kubectl apply -f https://git.io/weave-kube

也就是说，还有许多其他Pod网络提供商，请参阅

Kubernetes focus并不是网络本身，而是为第三方解决方案（如Weave和Flannel）提供了一个接口
