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

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

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,
