Dashboard 是一个基于网页的 Kubernetes 用户界面，允许用户在 Kubernetes 集群中部署和管理容器应用。它提供排错、集群资源管理、运行应用概览以及 Kubernetes 资源（如 Deployment、Job、DaemonSet 等）的创建与修改功能，是一个用户友好型 UI。接下来，我将介绍如何部署仪表盘，希望对您有所帮助！

  • 操作系统：CentOS Linux 7 (Core)
  • Containerd：1.6.33
  • Kubernetes：1.30.1

1、部署 Kubernetes - Dashboard

# 下载 recommended.yaml 文件
wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml# 提前下载需要的镜像（可选）
crictl image |grep kubernetesui# 修改 recommended.yaml，为 service->kubernetes-dashboard 配置为 NodePort 类型，并指定端口为 31313
vi recommended.yaml
...
kind: Service
apiVersion: v1
metadata:labels:k8s-app: kubernetes-dashboardname: kubernetes-dashboardnamespace: kubernetes-dashboard
spec:ports:- port: 80targetPort: 9090nodePort: 31313                # 可配置其他可用端口，或集群自动分配selector:k8s-app: kubernetes-dashboardtype: NodePort
...# 应用 recommended.yaml
kubectl apply -f recommended.yaml# 查看部署成功
kubectl get all -n kubernetes-dashboard# 为 serviceaccount->kubernetes-dashboard 创建 token，用于登录 dashboard 界面
kubectl create token kubernetes-dashboard -n kubernetes-dashboard# 浏览器访问 dashboard 界面,使用指定的 31313 端口，输入上方获取的 token 即可登录
https://x.x.x.x:31313

2、完整内容 recommended.yaml（已按上方步骤修改）

3、配置 Dashboard 拥有更多权限

# 给 serviceaccount->kubernetes-dashboard 绑定 clusterrole->cluster-admin 角色，赋予更大的权限（可选，可根据实际使用自定义 clusterrole 进行绑定）
kubectl create clusterrolebinding kubernetes-dashboard-admin --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:kubernetes-dashboard# 也可使用下方 yaml 创建，vi kubernetes-dashboard-admin.yaml
...
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding

subjects:
- kind: ServiceAccountname: kubernetes-dashboardnamespace: kubernetes-dashboard
...
kubecrl apply -f kubernetes-dashboard-admin.yaml# 重回浏览器访问 dashboard 界面，即可看到更多的 resources，并且能执行更多操作
