Kubernetes: resolve external DNS from pod

Archive Rancher 1.x
1

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.
Maybe related to https://github.com/rancher/rancher/issues/5041 ?
