description |
I'm facing issues with OpenStack VMs built from Ubuntu 18.04 cloud image and configured with multiple NICs. I have a solution working on 16.04, which doesn't do any more since the introduction of netplan.
Requirements:
- Multiple interfaces connected to different networks.
- All NICs configured via DHCP to ensure IP address, but also parameters like MTU adapt to the environment automatically.
- Default route is supposed to use one specific NIC and network.
The solution on 16.04 was customization of /etc/dhcp/dhclient.conf, such that all unique parameters are retrieved from only that interface. Example with ens3 being the intended authoritative interface:
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
send host-name = gethostname();
request subnet-mask, broadcast-address, time-offset,
netbios-name-servers, netbios-scope, interface-mtu,
rfc3442-classless-static-routes;
interface "ens3" { request routers, domain-name, domain-name-servers, domain-search, host-name,
dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers, ntp-servers; }
This does no longer work with netplan. I couldn't figure any netplan properties to configure DHCP client to that granularity. And /etc/dhcp/dhclient.conf no longer seems to be honored. As I can see in VM startup console log, each interface is getting default route assigned and the system remains unresponsive most of the times.
How am I supposed to solve this on a netplan managed system? |
[Impact]
DHCP configurations where custom settings (routes) need to be applied. This is a subset of the changes presented in bug 1759014.
[Test case]
1) Configure netplan for the particulars of the network by configuring an appropriate dhcp{4,6}-override stanza:
network:
version: 2
ethernets:
engreen:
dhcp4: true
dhcp4-overrides:
use-routes: false
route-metric: 3333
Additionally, if so required, add a custom routes to the configuration. e.g.
routes:
- to: 10.0.0.0/16
via: 13.4.55.78
(See https://netplan.io/reference#dhcp-overrides for the available options)
2) Run 'netplan apply' or reboot to have the configuration applied.
3) Validate that the routes / DNS are properly ignored and/or replaced by the defined values.
[Regression potential]
Minimal; this adds new values to the configuration generated for networkd or NetworkManager. Existing configurations will remain unchanged, but new configurations using the dhcp{4,6}-overrides fields will benefit from additional flexibility.
