| Ingress | *.<shturval_cluster_name>.<base_domain>. | Wildcard record for access to management cluster application functions |
| API server | api.<client_cluster_name>.<base_domain>. | A record for the client cluster application programming interface |
| Ingress | *.<client_cluster_name>.<base_domain>. | Wildcard record for access to client cluster applications |
- <base_domain> – organization DNS zone;
- <shturval_cluster_name> – management cluster name;
