Hi

In my pod, I need to be able to requests external resources, using globally known DNS.  
Unfortunately, no external DNS seems working in my pod deployed on a Rancher Kubernetes cluster.

Any help ? Is it possible to define which external DNS could be used for a pod ? Or as fallback for the Rancher DNS ?

Thanks.

I used base image `alpine`. I don’t have this problem with an `ubuntu`.
