Public bug reported:
Running a v2 network-config through cloud-init's net-convert we can see
that we're not passing it through, but importing and re-rendering lossy.
% cat simple-v2.yaml
network:
version: 2
# comment above ethernets
ethernets:
ens0:
dhcp4: true
match:
macaddress: 00:11:22:33:44:55
set-name: ens0
switchports:
# all cards on second PCI bus; unconfigured by themselves, will be added
# to br0 below
match:
name: enp2*
mtu: 1280
% PYTHONPATH=`pwd` ./tools/net-convert.py --network-data simple-v2.yaml
--kind yaml --output-kind netplan -d target
% cat target/etc/netplan/50-cloud-init.yaml
network:
version: 2
ethernets:
ens0:
dhcp4: true
switchports:
mtu: 1280
We lose comments and matching.
Also note, ./tools/net-convert.py has a bug, the order of parameters to
the rendering class changed.
