Docker on ubuntu nested on Hyper-v

Hi all.

Totally new to docker, and I have an issue I hope some one can help me with.

Running some Server 2016 Hyper-V hosts, i installed an VM with Ubuntu and i tryes Debian too. Install runs fine on both, but when make an container E.g. Rancher is getting no Ip address.

Short term, how do I fix that?

Ubuntu have full access to network and internet.

Cheers.
