[Starlingx-discuss] DNS resolution of instances enablement in the StarlingX

To enable DNS you need to create a yaml file and then override helm:
cat > neutron-overrides.yaml <<EOF
# update the neutron overrides and apply to stx-openstack
system helm-override-update stx-openstack neutron openstack --values neutron-overrides.yaml
system application-apply stx-openstack
I notice that you have already changed the configuration. Could you please check the configuration by following command:
kubectl get pod -n openstack | grep neutron-ovs
kubectl exec -it -n openstack $neutron-ovs-agent bash
cat /etc/neutron/neutron.conf | grep dns_domain
cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep extension_drivers
Could you please attach some logs for failing to attach the port to the VM. (like nova-conductor, nova-compute, nova-scheduler, neutron-server, neutron-ovs-agent, openstack server show vm)
For Designate component provide DNS, the following guide can be referenced:
You need to use helm override to change the configuration.

Subject: [Starlingx-discuss] DNS resolution of instances enablement in the StarlingX
Can somebody tell me how to enable DNS in the starlingX to resolve the instances name.
I saw in the openstack documentation https://docs.openstack.org/mitaka/networking-guide/config-dns-int.html but unable to associate a port to VM, it fails.
I had changed the configuration file in neutron helm and added as below
1. dns_domain = stx-mu.org
and also added the DNS external driver in ml2 plugin as below.
extension_drivers = port_security,dns
While researching more about the DNS configuration in the Openstack, I found that Designate component provide DNS as service. Do we have it in StarlingX or any plan for it.
