kubernetes部署dashboard

1. 简介

Dashboard 是基于网页的 Kubernetes 用户界面。 你可以使用 Dashboard 将容器应用部署到 Kubernetes 集群中，也可以对容器应用排错，还能管理集群资源。 你可以使用 Dashboard 获取运行在集群中的应用的概览信息，也可以创建或者修改 Kubernetes 资源 （如 Deployment、Job、DaemonSet 等等）。 例如，你可以对 Deployment 实现弹性伸缩、发起滚动升级、重启 Pod 或者使用向导创建新的应用。

Dashboard 同时展示了 Kubernetes 集群中的资源状态信息和所有报错信息。

2. 版本兼容性

k8s和dashboard版本存在兼容性关系，版本配套可以到下面的网页查询：https://github.com/kubernetes/dashboard/releases/

以下是部分配套关系：

Kubernetes version	dashboard version	备注
1.18	v2.0.0	完全支持
1.19	v2.0.4	完全支持
1.20	v2.4.0	完全支持
1.21	v2.4.0	完全支持
1.23	v2.5.0	完全支持
1.24	v2.6.0	完全支持
1.25	v2.7.0	完全支持
1.27	v3.0.0-alpha0	完全支持
1.29	kubernetes-dashboard-7.5.0	完全支持

本文使用的k8s版本为1.23，使用dashboard v2.5.0版本部署。

3. 安装

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.0/aio/deploy/recommended.yaml

如果yaml无法下载，可以手动打开网页拷贝到文件中。以下是v2.5.0版本文件内容。
