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
