This patch provides an initial firewall configuration that provides complete isolation of the cluster from the outside world. The only way to access the cluster is through the load balancer on ports 6443 (api), 443 (https), 80 (http) and currently 22623 (ignition). Sadly, we can't automatically apply these firewalls to hosts, since the hcloud terraform module has a bootstrapping problem[1], so this has to be done afterwards manually using the Webinterface or CLI. Since all instances are tagged already, it should be trivial to apply the right firewall rules based on the tag. Note on 22623, exposing this port through the loadbalancer permentently to the internet is not ideal and should be changed. However, I haven't come up with a better solution. This will be sorted out in the long run. [1]: hetznercloud/terraform-provider-hcloud#336
