Configure domain to point to Public Cloud Swarm cluster

Hello there !

I am building a public cloud infrastructure on OVH. This infra is based on openstack and docker swarm.
I would like to know if there is an automated way to configure my OVH domain name to point to my swarm cluster (via public IP) and would like to avoid having to make it point myself manually (I might reset the whole cluster from time to time).

Also, is there a way to access to the cluster non using the IP but via a custom domain name (something like [MY_CLOUD_ID].cloud.public.ovh.com?

Thanks a lot !
Ben
