What is the concept of renderer in a netplan configuration file?
What practical difference does it make between choosing a networkd and a NetworkNamager renderer?
Can anyone (in the second case) proceed with nmtui or nmcli?
The difference the renderer makes, is the decision to run either systemd-networkd or NetworkManager. This distinction is identified by a file in /etc/netplan/*.yaml.
networkd is normally used in server installations, where the network environment is fairly static.
NetworkManager is normally used in desktop installations, and was used in all prior versions of Ubuntu. NetworkManager is easier to use in environments where network requirements change a lot... like in wireless networking. nmcli/nmtui/etc are NetworkManager commands.
To use NetworkManager, your /etc/netplan/*.yaml file should look like:
network:
version: 2
renderer: NetworkManager
sudo netplan --debug generate
sudo netplan apply
reboot

1so if I opt for
renderer: NetworkManager, then I can runnmcli/nmtuito configure my network? what if I run nm and provide configurations that are conflicting with the ones in thenetplan.ymlfile? which one (the config entered via nm or theyamlsettings) prevails? – pkaramol Mar 3 '19 at 17:24 -
2@pkaramol once you specify
renderer: NetworkManageryou're done with all .yaml files, and all normal NetworkManager commands can be used. All conflict or error scripts will need to be rectified via NM. – heynnema Mar 3 '19 at 17:28
