I have an interface I want to bring up at boot but otherwise leave unconfigured. No DHCP, no static IP. Is there a way to do this with Netplan in 18.04?
I tried the following (where
enp10s0f1 is the device in question) but it still just leaves the interface down:
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: enp10s0f0: dhcp4: yes enp10s0f1: dhcp4: no
The reason this matters is I have LXD containers using that interface via macvlan bridging, so the interface needs to be up, but it doesn't need (and I'd rather not have) an IP address on the host. I'd really prefer not to need to remember
ip link set up enp10s0f1 when I reboot.
I found this bug report in Netplan's Launchpad that looks related, but as best as I can tell, it's for the opposite case: tell Netplan to configure an interface but don't automatically bring it up. However, it does sort of suggest that what I want to do isn't possible yet either. Is that the case? Is there any workaround besides abandoning Netplan?
