Kubernetes(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 

安装

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
