I am currently using Newton with ubuntu 16.04 and would like to migrate to Rocky over Ubuntu 18.04. But I discovered that Ubuntu 18.04 is using netplan instead of ifupdown to manage the network ressources. I realize that it is more an Openstack question but since Openstack required quite a bit of complexity in the networking I think posting the question here is more adequate.
I have the following interfaces file for ubuntu 16.04 and looking on documentation on how to convert that setup to netplan ?
Any body can help ? Thanks
Here is my current ifupdown configuration
