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。
