Question

我在/ var收到錯誤消息/ log/messages中，當試圖建立與命令 「kubeadm初始化」 集羣：

我的Linux版本是：

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

碼頭工人的版本是：

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

Kubernetes版本：

[root@master ~]# kubeadm version

而CNI已安裝：

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

任何人面對similiar問題？

Answer 1

您只需安裝某種（第三方）Pod網絡，如指南中所述。

就我個人而言，我正在使用Weave或Flannel。例如，您可以安裝編織這樣：

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

也就是說，還有很多其他的波德網絡供應商以及見http://kubernetes.io/docs/admin/addons/。

Kubernetes的重點本身並不是網絡，而是暴露了第三方解決方案的接口，如Weave和Flannel。
