console-conf does not allow to set up dns for static ip

[Federico Gimenez]

[Impact]
subiquity and other nplan users may need to include DNS information when setting up a system.

[Test case]
1) set up a system with a netplan configuration including the nameserver: key for an interface, such as the following:

network:
  ethernets:
    enxb827ebd3f20f:
      addresses: [192.168.0.200/24]
      nameservers: 192.168.0.10
  version: 2

Verify that the nameserver settings are properly installed to the system (see /etc/resolv.conf or /run/systemd/resolve/resolv.conf)

[Regression potential]
Existing configurations that do not include nameserver configs should continue to work as-is; without nameserver data if using static addresses, or with the nameserver data retrieved from DHCP.

[Original bug report]
There's no way to setup DNS info for static IP configuration, which leads to broken name resolution:

fgimenez@localhost:~$ cat /etc/netplan/00-snapd-config.yaml
# This is the network config written by 'console-conf'
network:
  ethernets:
    enxb827ebd3f20f:
      addresses: [192.168.0.200/24]
  version: 2
fgimenez@localhost:~$ ping www.ubuntu.com
ping: unknown host www.ubuntu.com
fgimenez@localhost:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

Selecting DHCP config from console-conf all works fine:

fgimenez@localhost:~$ cat /etc/netplan/00-snapd-config.yaml
# This is the network config written by 'console-conf'
network:
  ethernets:
    enxb827ebd3f20f:
      addresses: []
      dhcp4: true
  version: 2

I don't think netplan supports this yet :(

[Martin Pitt (pitti)]

I'm working on this since this morning.

[Martin Pitt (pitti)]

In xenial, specifying search domains when using networkd does not work. I filed bug 1635256 about this. Other than that, things look good in both x and y.

Frederico, Michael, is this working/sufficient for you? If so, please mark as verification-done so that we can release this.

[Federico Gimenez (fgimenez)]

Hi Martin, I can confirm that this works now, verified on amd64, core v16.04.1 r324.

Thanks!

Hello Federico, or anyone else affected,

Accepted nplan into yakkety-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/nplan/0.23~16.10.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

[Mathieu Trudel-Lapierre (cyphermox)]

Verification done for yakkety:

Preparing to unpack .../nplan_0.23~16.10.1_amd64.deb ...
Unpacking nplan (0.23~16.10.1) over (0.12) ...
Setting up nplan (0.23~16.10.1) ...

Verified that nameservers can be set via netplan in yakkety-proposed; used the configuration below:

network:
  version: 2
  renderer: networkd
  ethernets:
    ens4:
      dhcp4: yes
      nameservers:
        search: [ 'cyphermox.net' ]
        addresses: [ 10.10.10.1 ]

The correct nameservers are used by systemd-resolved, but /etc/resolv.conf will not include the values directly (because it gets 127.0.0.53, as a side-effect of the use of systemd-resolved behind resolvconf.
