因为我旧有的k8s集群，已经部署了不少服务，所以考虑直接在该版本安装KubeSphere
不知道是否能够兼容

    有人知道怎么降级把k8s从v1.21.1降级到v1.20.X吗

    MephistoLynn

    Get “https://10.96.0.1:443/api?timeout=32s”: dial tcp 10.96.0.1:443: i/o timeout

    很明显 集群网络有问题

      我的1.21.x安装也失败了，redis-ha-server初始化失败。

      4 天 后

      可以安装的，但是日志组件不兼容containerd，需要自己改下
