尝试在我的 kubernetes 集群上使用 helm。helm init一切顺利，但尝试安装或只是helm list给出这个错误。
$ helm list

我已经在 Google 上搜索了好几个小时，但似乎没有办法解决这个问题。以下是我的集群信息：

- 我尝试过的：
- 重启所有节点
- 删除 Calico 并重新安装
- 更新 Calico
- 在“默认”命名空间中安装 Helm
- 头撞在桌子上
答案1
我可以通过使用不同的 CIDR 重新启动集群来解决这个问题（之前使用与主机虚拟机相同的 CIDR（192.168.0.0/16）。我使用了 172.16.0.0/16 并且它立即起作用了。
