安装dashboard
k8s-1.25.0对应dashboard版本为v2.7.0，查看合适版本。
找到合适版本后apply，执行指令后可以看到新增的内容。
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
新增的内容
修改service/kubernetes-dashboard的暴露服务类型为NortPort
这时候访问暴露的dashboard端口能看到，需要使用token登录。
创建dashboard管理用户
cat > dashboard-svc-account.yaml <<-EOF
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: dashboard-admin
namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: dashboard-admin-cluster-role
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: dashboard-admin
namespace: kubernetes-dashboard
EOF
kubectl apply -f dashboard-svc-account.yaml
生成token后填入登录即可看到界面。
kubectl -n kubernetes-dashboard create token dashboard-admin
k8s-dashboard
