安装KubeSphere最好的方法就是参考官方文档,而且官方文档是中文的。官网地址:https://kubesphere.com.cn/

https://github.com/kubesphere/kubesphere/blob/master/README_zh.mdKubernetes(K8S) kubesphere 介绍安装提前条件:使用 Kubeadm 部署 Kubernetes(K8S) 安装--附K8S架构图使用 Kubeadm 部署 Kubernetes(K8S) 安装 -- 持久化存储(NFS网络存储)Kubernetes(K8S) 安装 Metrics-Server

# 检查 K8S 版本,低版本需要升级[root@k8smaster kubesphere]# kubectl version

如果出现下面错误,需要安装 storageclass、persistentVolumeClaim

TASK [preinstall : KubeSphere | Stopping if default StorageClass was not found] ***fatal: [localhost]: FAILED! => {    "assertion": "\"(default)\" in default_storage_class_check.stdout",    "changed": false,    "evaluated_to": false,    "msg": "Default StorageClass was not found !"}
# 删除[root@k8smaster kubesphere]# kubectl delete -f kubesphere-installer.yaml[root@k8smaster kubesphere]# kubectl delete -f cluster-configuration.yaml# 安装完 storageclass  后,重新安装[root@k8smaster kubesphere]# kubectl apply -f storageclass.yaml[root@k8smaster kubesphere]# kubectl apply -f persistentVolumeClaim.yaml[root@k8smaster kubesphere]# kubectl apply -f kubesphere-installer.yaml[root@k8smaster kubesphere]# kubectl apply -f cluster-configuration.yaml
