KubeSphere版本信息

尚未安装kubesphere，用的是 3.2.0版 kk， 准备分步骤安装：

1. 只安装kubernetes –with-kubenetes

2. 安装kubernetes dashboard

3. 安装rook-ceph

4. 安装kubesphere

   目前只安装了第一步以后，发现集群有问题。

问题是什么

1. kubectl describe pod calico-kube-controller -n kube-system

   Events:

   2. kubectl logs -n kube-system calico-kube-controllers-68586cd975-zqb7v

   3. coredns也是类似的报错信息。

BTW： 我在安装的时候，纯内网环境，用httpproxy 和 https_proxy利用另一台主机作为正向代理机下载的images.
