Create managed cluster using VPC IP addresses #40

Open halindrome opened 2 years ago

halindrome commented 2 years ago

The latest changes to gmd work really well on DigitalOcean. Thanks!

I cannot seem to find documentation about how to tell the cluster that it should communicate between the nodes using the internal (VPC) IP addresses of the various hosts instead of their public IP addresses.

Also, it would be great if there were a way to define a DigitalOcean droplet tag (or tags) for any new droplets created, since that would be a good way to enforce firewall rules and policies. Is there a possibility of this?

Just to be clear, the reason I am asking this is that transfers among droplets at DO on their private network interfaces do not count toward the transfer allowance for nodes - they are effectively free. Transfers on the public interface do count against the allowance, so it would be much better to have the Galera nodes coordinating with one another on the private interfaces.

We currently do not support data transfer using internal IP addresses for any cloud provider we support. However, this will be addressed in one of the future releases (though, no estimations yet).

As for the labels thank you for the proposal, I will put it on our list.
