一、安装之前准备

andy@ThinkPad:~$ kubectl get storageclass

二、安装KubeSphere

复制代码

$ kubectl create namespace kubesphere-system

$ helm install kubesphere kubesphere/ks-installer --namespace kubesphere-system -f values.yaml
NAME: kubesphere
LAST DEPLOYED: Thu Oct  2 21:04:13 2025
NAMESPACE: kubesphere-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
1. Get the application URL by running these commands:
  export NODE_PORT=$(kubectl get --namespace kubesphere-system -o jsonpath="{.spec.ports[0].nodePort}" services ks-console)
  export NODE_IP=$(kubectl get nodes --namespace kubesphere-system-o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT


$ kubectl get pods -n kubesphere-system -w

kubesphere/ks-installer:v3.2.1 镜像不存在或已被移除（KubeSphere v3.2.1 是旧版，社区已转向 v3.4.x）。此外，KubeSphere 官方 Docker Hub 镜像源已下架（项目闭源影响），导致拉取失败。

解决方案：更换国内资源，包括：

Docker Hub 镜像加速器：加速从 Docker Hub 拉取镜像。
KubeSphere 镜像仓库替换：使用阿里云等国内镜像源替换官方镜像（registry.cn-beijing.aliyuncs.com/kubesphereio/）。
Helm 仓库：官方 Helm repo 已不可靠，可切换到阿里云镜像或手动下载。
