kubernetes 安装 kubernetes-dashboard 7.x

kubernetes 安装 kubernetes-dashboard 7.x

介绍

Kubernetes仪表板是Kubernetes集群的通用、基于Web的UI。它允许用户管理集群中运行的应用程序并对其进行故障排除，以及管理集群本身。

从7.x版开始，不再支持基于Manifest的安装。现在只支持基于Helm的安装。由于多容器设置和对Kong网关API代理的严重依赖 要轻松支持基于清单安装是不可行的。

安装

# 添加源信息
helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/

# 默认参数安装
helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kube-system

# 我的集群使用默认参数安装 kubernetes-dashboard-kong 出现异常 8444 端口占用
# 使用下面的命令进行安装，在安装时关闭kong.tls功能
helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --namespace kube-system --set kong.admin.tls.enabled=false
