k8s交付heapster，启动pod失败，发现是harbor仓库问题

应用资源配置清单后，heapster对应的pod始终没有启动。

[root@hdss7-22 ~]# kubectl get pods -n kube-system NAME                                    READY   STATUS             RESTARTS   AGE coredns-6b6c4f9648-ddlq8                1/1     Running            0          13d heapster-b5b9f794-bwz9z                 0/1     ImagePullBackOff   0          10m kubernetes-dashboard-76dcdb4677-x6r8f   1/1     Running            0          2d5h traefik-ingress-vpxr7                   1/1     Running            0          2d2h traefik-ingress-zxw69                   1/1     Running            0          11d

在dashboard，查看pod状态，报错如下：

Failed to pull image "harbor.od.com/public/heapster:v1.5.4": rpc error: code = Unknown desc = Error response from daemon: Get http://harbor.od.com/v2/public/heapster/manifests/v1.5.4: Get http://harbor.od.com:180/service/token?scope=repository%3Apublic%2Fheapster%3Apull&service=harbor-registry: dial tcp 10.4.7.200:180: connect: connection timed out

登录到harbor，报错返回502
