  # Kubernetes Dashboard
Kubernetes Dashboard 是 Kubernetes 集群的基于 Web 的通用 UI。它允许用户管理在群集中运行的应用程序并对其进行故障排除,以及管理群集本身。
由于 Kubernetes API 版本之间的重大更改,某些功能可能无法在仪表板中正常运行,这也导致了 kubernetes-dashboard 的兼容性问题比较严重,最好一个版本使用一个版本最稳定的 dashboard。

# kubesphere
官方地址:https://kubesphere.io/zh/
KubeSphere 愿景是打造一个以 Kubernetes 为内核的云原生分布式操作系统,它的架构可以非常方便地使第三方应用与云原生生态组件进行即插即用(plug-and-play)的集成,支持云原生应用在多云与多集群的统一分发和运维管理。
# 本地存储动态 PVC
# 在所有节点安装 iSCSI 协议客户端(OpenEBS 需要该协议提供存储支持)
yum install iscsi-initiator-utils -y
# 设置开机启动
systemctl enable --now iscsid
# 启动服务
systemctl start iscsid
# 查看服务状态
systemctl status iscsid
# 安装 OpenEBS 
kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml
# 查看状态(下载镜像可能需要一些时间)
kubectl get all -n openebs
# 在主节点创建本地 storage class
kubectl apply -f default-storage-class.yaml
