一、最小化部署 kubesphere
1、在已有的 Kubernetes 集群上部署 KubeSphere，下载 YAML 文件:
wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.0/kubesphere-installer.yaml
wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.0/cluster-configuration.yaml
2、执行以下命令部署 kubesphere：
kubectl apply -f kubesphere-installer.yaml
kubectl apply -f cluster-configuration.yaml
二、中途遇到的报错及解决方法
说明：这里基本所有同学都不可能成功安装，因为我们使用的Host Storage存储，因此需要手动创建存储类，会出现以下报错信息：
fatal: [localhost]: FAILED! => {
"assertion": "\"(default)\" in default_storage_class_check.stdout",
"changed": false,
"evaluated_to": false,
"msg": "Default StorageClass was not found !"
}
解决方法如下：
1、创建文件storageclass.yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
2、创建文件persistentVolumeClaim.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: local-pve
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 20Gi
storageClassName: local-storage
3、修改sc为默认标识为default
kubectl patch sc local-storage -p '{"metadata": {"annotations": {"storageclass.beta.kubernetes.io/is-default-class": "true"}}}'
## local-storage 是 sc 的名称
三、重新部署 kubesphere
1、重新执行以下命令即可 kubesphere
kubectl apply -f kubesphere-installer.yaml
kubectl apply -f cluster-configuration.yaml
2、检查安装日志：
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f
3、安装完成后，您会看到以下消息：

4、查看pod是否正常运行
[root@kubernetes-master ~]# kubectl get pod,svc -n kubesphere-system
NAME READY STATUS RESTARTS AGE
pod/ks-apiserver-b7ddc4f5c-ss4kz 1/1 Running 0 26h

service/ks-controller-manager ClusterIP 10.103.231.3 <none> 443/TCP 26h
四、登录 kubesphere 控制台
