无法通过Kubectl代理打开服务

如何解决无法通过Kubectl代理打开服务

➜ kubectl get svc  
NAME                     TYPE           CLUSTER-IP       EXTERNAL-IP                             PORT(S)    AGE
airflow-flower-service   ClusterIP      172.20.119.107   <none>                                  5555/TCP   54d
airflow-service          ClusterIP      172.20.76.63     <none>                                  80/TCP     54d
backend-service          ClusterIP      172.20.39.154    <none>                                  80/TCP     54d

➜ kubectl proxy

xdg-open http://127.0.0.1:8001/api/v1/namespaces/edna/services/http:airflow-service:/proxy/#q=ip-192-168-114-35

并且失败

Error trying to reach service: 'dial tcp 10.0.102.174:80: i/o timeout'

但是，如果我通过kubectl port-forward公开该服务，则可以在浏览器中打开该服务

kubectl port-forward service/backend-service 8080:80 -n edna
xdg-open HTTP://localhost:8080

那么如何通过该长网址打开服务（类似于我们打开kubernetes仪表板的方式？

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/overview?namespace=default

如果我使用CURL查询API，则会看到输出

➜ curl http://127.0.0.1:8001/api/v1/namespaces/edna/services/backend-service/

    }
  },"spec": {

        "protocol": "TCP","port": 80,"targetPort": 80
      }
    ],"selector": {

}  

解决方法

代替您的URL：

http://127.0.0.1:8001/api/v1/namespaces/edna/services/http:airflow-service:/proxy

尝试不使用“ http：”

http://127.0.0.1:8001/api/v1/namespaces/edna/services/airflow-service/proxy
