Extend documentation for new users

[tuxerrante]

Hi,
I'd like to try kubernetai to mirror some service from a remote cluster-2 to another one cluster-1 on AKS.

But we can't understand what are the steps and the implications from the documentation here.

Of course, for this to work, you will also need to ensure that Service Endpoint IPs are routable across the clusters, which is possible to do, but not necessarily the case by default.

Could you add some command to verify this?

After the cloning of the project and the makes, what should we do?

Is there a way to backup the current coreDNS, before deploying this?

Thanks!

Perhaps https://github.com/coredns/multicluster-dns can help answer some of your questions.
It's specific to GKE, but concepts would be similar to AKS.
