K8s安装仪表盘-最新简明教程

1. 创建服务

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

# 查看服务，此时的Type为ClusterIP,无法对外提供服务
kubectl get svc -A

查看recommended.yaml, 其中已包含了ServiceAccount, ClusterRoleBinding项，即默认的「用户」和「角色」，

如需自定义用户角色，可参考kubernetes-dashboard官方文档。

2. 修改端口配置

export KUBE_EDITOR="vim"
kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

修改如下两处配置项：

apiVersion: v1
kind: Service
metadata:
spec:
  clusterIP: 10.104.42.244
  clusterIPs:
  - 10.104.42.244
  externalTrafficPolicy: Cluster
  internalTrafficPolicy: Cluster
  ipFamilies:
  - IPv4
  ipFamilyPolicy: SingleStack
  ports:
  - nodePort: 30001   # 自定义的外部端口(30000+)
    port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: NodePort      # 改为NodePort
status:
  loadBalancer: {}

---

3. 获取令牌

# 先获取token名称，再获取令牌信息
kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret|grep admin-user|awk '{print $1}')

---

4. 浏览器查看

使用上一步获得的token，访问任意集群节点，⚠️ 如：https://10.0.0.11:30001

kubernetes-dashboard

---

5. 删除服务

# 用于服务异常或其他原因
kubectl delete service kubernetes-dashboard -n kubernetes-dashboard

---
