У нас есть настройка кластера с несколькими узлами, теперь попробуйте установить панель мониторинга.

Я запустил команду kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.4.0/aio/deploy/recommended.yaml , и она развернула все ресурсы.

Я проверяю, создана ли служба.

 # kubectl get services -n kubernetes-dashboard NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE dashboard-metrics-scraper ClusterIP 10.103.75.109 lt;nonegt; 8000/TCP 4m53s kubernetes-dashboard ClusterIP 10.106.194.108 lt;nonegt; 443/TCP 4m53s  

Затем попробуйте получить доступ к URL-адресу службы.

Затем я выполняю действия по преобразованию ClusterIP в NodePort ,

Обслуживание перед конвертацией.

 # kubectl -n kubernetes-dashboard describe service kubernetes-dashboard Name: kubernetes-dashboard Namespace: kubernetes-dashboard Labels: k8s-app=kubernetes-dashboard Annotations: lt;nonegt; Selector: k8s-app=kubernetes-dashboard Type: ClusterIP IP Family Policy: SingleStack IP Families: IPv4 IP: 10.106.194.108 IPs: 10.106.194.108 Port: lt;unsetgt; 443/TCP TargetPort: 8443/TCP Endpoints: 192.168.211.130:8443 Session Affinity: None Events: lt;nonegt;  

Service after edit using kubectl -n kubernetes-dashboard edit service kubernetes-dashboard command.

 # kubectl -n kubernetes-dashboard describe service kubernetes-dashboard Name: kubernetes-dashboard Namespace: kubernetes-dashboard Labels: k8s-app=kubernetes-dashboard Annotations: lt;nonegt; Selector: k8s-app=kubernetes-dashboard Type: NodePort IP Family Policy: SingleStack IP Families: IPv4 IP: 10.106.194.108 IPs: 10.106.194.108 Port: lt;unsetgt; 443/TCP TargetPort: 8443/TCP NodePort: lt;unsetgt; 32358/TCP Endpoints: 192.168.211.130:8443 Session Affinity: None External Traffic Policy: Cluster Events: lt;nonegt;  

тогда curl https://10.106.194.108:32358 -k никогда не возвращайте данные :(.

Я проверяю IP-адрес модуля, и он работает.

Как проверить, почему он не работает после перехода на NodePort ?

служба k8s nodeport работает следующим образом :

это означает, что ваша действительная конечная точка будет

 http://{NODE_IP}:{PORT}
