Hi Mark, I have already contributed to the findings below so I am not adding anything here. This reply is to add more tags to the subject to attract more attention from Ubuntu and Charms folks. Cheers! -yoctozepto On Fri, Feb 12, 2021 at 1:21 PM Mark Goddard <mark@stackhpc.com> wrote:
Hi,
We're working on adding Ubuntu support to Kayobe, and are at the stage of deciding on which tool to use for host network configuration. The Ansible role we use supports /etc/network/interfaces, but we're thinking it might be sensible to choose something more modern before we get locked in. There are 3 reasonable options, as far as we can tell:
* netplan: installed by default on 20.04 server images. Seems like a fairly simple solution, but I have read some reports of missing features.
* systemd-networkd: the default renderer for netplan. Standard systemd style interface. We might get around the missing features by using this directly.
* NetworkManager: the default on Ubuntu desktop, but have heard it can be a bit heavy and does too much without being asked to. I've also heard that more recent versions are improved. The main reason we would go this route would be for consistency with CentOS/RHEL.
Any feedback of experience with these and their suitability for use in OpenStack cloud infrastructure would be appreciated.
Thanks, Mark
