Glad that helped. I'm confused as to why cloud-init doesn't add the mac
addresses - it does in my VMs. Let's ask them; I'll add them to the bug.
** Description changed:
+ == cloud-init query ==
+
+ Cloud-init isn't adding MAC addresses in the match stanza for various
+ network interfaces in /etc/netplan/50-cloud-init.yaml, which is leading
+ to unexpected results. Is there any reason this would happen?
+
+
+ == Original Description ==
+
Running nplan 0.30 on Ubuntu 17.10. From what I can tell, the
ethernets/interface/mtu field isn't applied when testing against a
private ethernet adapter.
Using a netplan yaml file (/etc/netplan/10-ens7.yaml):
---
network:
- version: 2
- renderer: networkd
- ethernets:
- ens7:
- mtu: 1450
- dhcp4: no
- addresses: [10.99.0.13/16]
+ version: 2
+ renderer: networkd
+ ethernets:
+ ens7:
+ mtu: 1450
+ dhcp4: no
+ addresses: [10.99.0.13/16]
---
Then running "netplan apply" (or rebooting), yields the following:
---
6: ens7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
group default qlen 1000
- link/ether 52:54:00:2a:19:bc brd ff:ff:ff:ff:ff:ff
- inet 10.99.0.13/16 brd 10.99.255.255 scope global ens7
- valid_lft forever preferred_lft forever
- inet6 fe80::5054:ff:fe2a:19bc/64 scope link
- valid_lft forever preferred_lft forever
+ link/ether 52:54:00:2a:19:bc brd ff:ff:ff:ff:ff:ff
+ inet 10.99.0.13/16 brd 10.99.255.255 scope global ens7
+ valid_lft forever preferred_lft forever
+ inet6 fe80::5054:ff:fe2a:19bc/64 scope link
+ valid_lft forever preferred_lft forever

Is this a bug in netplan, or am I misunderstanding the YAML syntax?
Best,
Andrew
