Private DNS Configuration

Internal DNS resolution for the OSMO UI service running on an internal LoadBalancer.

[!NOTE] Part of the Deployment Guide. Return there for navigation and deployment order.

📋 Prerequisites

• Platform infrastructure deployed (cd infrastructure/terraform && terraform apply)
• VPN Gateway deployed (VPN Gateway)
• OSMO UI service running with internal LoadBalancer IP

🚀 Usage

Get the OSMO UI LoadBalancer IP from your cluster:

kubectl get svc -n osmo-control-plane osmo-ui -o jsonpath='{.status.loadBalancer.ingress[0].ip}'

Deploy the DNS zone:

cd infrastructure/terraform/dns
terraform init
terraform apply -var="osmo_loadbalancer_ip=10.0.x.x"

⚙️ Configuration

Variable	Description	Default
osmo_loadbalancer_ip	Internal LoadBalancer IP	(required)
osmo_private_dns_zone_name	DNS zone name	osmo.local
osmo_hostname	Hostname within zone	dev

💡 How It Works

1. DNS zone (e.g., osmo.local) is linked to the VNet
2. A record (dev.osmo.local) points to the LoadBalancer IP
3. VPN clients use the Private DNS Resolver to resolve internal names
4. Access OSMO UI at http://dev.osmo.local when connected via VPN
