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

[Xu, Chenjie]

Hi Yatindra,

To enable DNS you need to create a yaml file and then override helm:
cat > neutron-overrides.yaml <<EOF
conf:
neutron:
   DEFAULT:
     dns_domain: wrs_dns.com
plugins:
   ml2_conf:
     ml2:
       extension_drivers: dns
EOF

# update the neutron overrides and apply to stx-openstack
source /etc/platform/openrc
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:
https://docs.openstack.org/mitaka/networking-guide/config-dns-int.html#config-dns-int-ext-serv
You need to use helm override to change the configuration.

Best Regards,
Xu, Chenjie

Hi All,

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.

Mit freundlichen Grüßen/ with best regards,
