do you mind provide a full log for the netplugin on node kube-dns is running ?

It was a proxy configuration problem in my environment. I added netmaster to no_proxy and it succeeded cleanly. I will close the issue.

Hi I have the same problem. you added netmaster to no_proxy ,Does it means your netmaster the way to access the Internet？ @moonek
