If you want to provision master or node VMs that don't use floating ips, write on a `my-terraform-vars.tfvars` file, for example:
```
number_of_k8s_masters = "1"
number_of_k8s_masters_no_floating_ip = "2"
number_of_k8s_nodes_no_floating_ip = "1"
number_of_k8s_nodes = "0"

This will provision one VM as master using a floating ip, two additional masters using no floating ips (these will only have private ips inside your tenancy) and one VM as node, again without a floating ip.

if you choose to add masters or nodes without floating ips (only internal ips on your OpenStack tenancy), this script will create as well a file `contrib/terraform/openstack/k8s-cluster.yml` with an ssh command for ansible to be able to access your machines tunneling through the first floating ip used. If you want to manually handling the ssh tunneling to these machines, please delete or move that file. If you want to use this, just leave it there, as ansible will pick it up automatically.
