Some Port Properties Cannot Be Set

[Ayhan ilhan]

Hi,

Some port properties like dns-name cannot be set. We got mismatch error in some tempest tests as below. I debugged it and i saw that the dns-name properties cannot be set when creating a port. I checked with openstack cli commands and i saw dns-name properties cannot be set. I can set this properties in wallaby version.

Openstack version: Zed
Openstack cli version: 6.4.0

Some Tempest Tests:

Hi,

These tests pass in our gate. Do you have your system configured correctly? For example, have you defined a dns_domain value in neutron.conf?

Here's a link to a recent job, if you search for 'dns' you will see all the things it sets:

https://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_4ee/905755/2/check/neutron-tempest-plugin-openvswitch/4ee7626/job-output.txt

fyi, that output will not be around forever, but you can look at any recent neutron patch and find a similar job.

Hello:

In order to be able to define the DNS records of a port, you need to enable the extension driver "dns":
  $ cat /etc/neutron/plugins/ml2/ml2_conf.ini
  [ml2]
  extension_drivers = ...,dns

You should also define a DNS domain different from the default one "openstacklocal.". This should be set in the neutron configuration:
  $ cat /etc/neutron/neutron.conf
  [DEFAULT]
  dns_domain = fistro.

Then you'll be able to define a DNS name per port.

Regards.

Hi,

I didn't define dns_domain value in neutron.conf at zed version. But i defined wallaby version.

Wallaby Version:
# cat /etc/kolla/neutron-server/ml2_conf.ini
[ml2]
extension_drivers = ...,dns

Zed Version:
# cat /etc/kolla/neutron-server/ml2_conf.ini
[ml2]
extension_drivers = ...,subnet_dns_publish_fixed_ip
